Alternator Problems and Repair

Alternator Problems and RepairGiven that we see a number of alternator issues at Sundance Automotive Repair in Lakewood, we want to share some information on alternator problems and repair that would be helpful to you as a vehicle owner. Issues with an alternator are common enough that at some point during the life of your vehicle, it will probably need a replacement. The alternator is part of your car’s charging system, which is essential to the workings of all things electric in your car. If it’s not working properly or fails, you will likely find yourself stranded on the side of the road.

Basics of How Your Alternator Works

The alternator helps maintain the battery of your car. Essentially, the alternator uses the engine’s power to create electricity then sends it to the battery to keep the battery charged.

The engine’s power arrives at the alternator via the serpentine belt, also known as the engine drive belt. Because of this, it is important to keep the belt tight and running well. This is also why you should replace this belt as soon as a new one is needed. Most people don’t realize that your car uses a great deal of electrical power: windshield wipers, lights, the radio, and other parts rely on and use a lot of electricity, especially when combined. If all these things are operating at the same time, it would drain the battery in your car fast. The alternator stops the battery from being run down and keeps it fully charged at all times.

Signs Your Alternator Might Have a Problem

It can be hard to diagnose an alternator problem without any tools. Problems with the battery are very similar to problems with the alternator and vice versa: for example, the car doesn’t start, your battery goes dead, the battery light goes on and the serpentine belt squeals. Other signs include: having to jump-start your car frequently and dimming lights while operating the vehicle. These are the most common signs that you might have an alternator problem or a potential battery problem. It is important to take care of this quickly because it can create problems and failures with other systems in your car.

Check Your Alternator Voltage

To confirm that the issue is a faulty alternator and not the battery, you will need to use a digital voltohmmeter or DVOM. The DVOM is also called a voltmeter. This tool will allow you to check quickly and easily to find out how much voltage your alternator is putting out.

  • The first step is turning your engine off. You will need to restart your vehicle later for another test, but for now, it needs to stay off.
  • The red lead of your voltmeter should be placed on the positive post of your battery and the black lead should be placed on the negative post.
  • Set your voltmeter to read DC volts if it is not already at this setting. The reading should be above 12.65 volts. This reading would confirm that the battery is fully charged. If the reading is less than 12.65 volts, then either your battery or alternator has an issue.
  • Next, take the leads off and start your car. Then, return the leads to the appropriate posts on your battery, being careful not to catch the leads on the serpentine belt or any other engine part. If you get a 13.5 to14.5-voltt range, then the alternator is probably not the issue. It is possible that the alternator is intermittently bad. That does happen on occasion, in which case, you would need to perform the test several times. If the volt range is consistently good, then you have a battery problem and it is time to get your battery tested.


Repairing a Defective Alternator

You can bring your vehicle and alternator into a repair shop, such as Sundance Automotive Repair in Lakewood, or you can perform the repair yourself if you have a bit of knowledge about your and car repairs in general. While swapping out your alternator for a new one isn’t very difficult, putting the serpentine belt on correctly definitely requires a diagram to ensure you replace it right. If it isn’t replaced just right, you’ll continue to experience issues with your electrical system, even damage or destroy the belt.

Diagnostic and repair information for your specific vehicle is imperative to alternator repair, as well as maintaining, troubleshooting, and fixing your vehicle yourself. To get the diagnostic and repair details specific to the year, make and model of your vehicle, ALLDATAdiy is a good online resource that will help you locate information for your vehicle. It’s also less expensive than buying a factory manual. Additionally, the site offers detailed diagrams and step-by-step instructions that are more thorough than what is available in most printed manuals.

To replace your alternator:

  • First, you need to disconnect the battery.
  • Next, take out the serpentine belt (be sure you have that diagram).
  • Finally, loosen and remove the bolts for the alternator and take off the wiring connectors.
  • To reinstall the new alternator, connect the wiring to the alternator and replace the bolts holding the alternator in place.
  • Follow the serpentine belt diagram carefully to replace the serpentine belt. Double check that the belt is put in place correctly.
  • Finally, reconnect the battery.


Alternatively, if you decide to have an auto-repair shop perform alternator repair, it is generally not one of the more expensive repairs and does not take very much time.

Ultimately, knowing more about how the alternator in your vehicle works in conjunction with the battery will help you understand better how to troubleshoot issues with your electrical system. Knowing more about alternator problems and repair will also help you determine if this is a project you want to undertake yourself or if it is something you would rather leave to the experts at Sundance Automotive Repair in Lakewood. If you decide to bring it to us, you can rest assured that we’ll provide quality work at a fair and honest price.

For Summer Oil Changes, Do You Need a Heavier Weight?

For Summer Oil Changes, Do You Need a Heavier Weight?For summer oil changes, do you need a heavier weight? With winter behind us, it’s time to get your car tuned up at Sundance Automotive Repair in Lakewood and this is a question we get often. And while using the right oil for your car is important, let’s look at whether there really are any benefits to using a heavier weight oil in the summer.

According to a Popular Mechanics article, the old wisdom for changing oil was to use a lighter oil weight in the winter and a heavier weight in the summer. But that was back when the oil formulations only had one viscosity, and the oil would thin out if it was heated in the summer weather. When it got cold in the winter the oil would become thick and the pumps couldn’t properly lube the engine. To fix the problem, a lightweight oil such as 10-weight was used for cold weather, so it would flow. Then a heavier 30- or 40-weight oil was used in the summer months to stop the oil from breaking down in the hot weather.

But this is no longer the case when you come in for an oil change. You do not need to change your oil’s weight for the summer and winter because we now have multi-viscosity oil that flows when it’s cold, then thickens and protects better when it’s hot. This handles the needs of both weather types and prevents the need for seasonal oil changes.

Not only has the oil become effective across temperatures, but new engines are also designed and tested to work specifically with only the type of oil listed in your owner’s manual. If you have an older car you can still use the newer and better oils. In deciding which of the newer oils are best for the older cars, base the first viscosity on your climate, and use the original oil spec for the operating weight. Most older cars can perform fine with 10W30.

Newer synthetic oil has better and longer-lasting performance in all the critical areas. Synthetic oil gives better performance in extreme temperatures which makes cranking easier in the cold and gets lubrication to critical components faster. It flows better at freezing temperatures than conventional oil. It is more chemically stable and doesn’t evaporate as easily or break down in the high heat from your vehicle engine. This lets it resist turning into sludge, which can cause engine problems. Synthetic oil has less evaporative loss, a higher viscosity index (resistance to thinning as temperatures rise is the viscosity index), and greater resistance to oxidation thermal breakdown and sludge problems.

While synthetic may cost more, it lasts longer so your vehicle doesn’t need an oil change as often. Your car may actually be able to last up to 7,000 to 10,000 miles between oil changes. Synthetics also have complex additive packages for improving performance in both normal and extreme conditions.

While you should always follow the manufacturer’s suggestions on what oil to use in your car, the answer to the question, for summer oil changes, do you need a heavier weight, is no. Bring your car into Sundance Automotive Repair in Lakewood for all your oil changes and tune-ups. We’ll take great care of your vehicle all year long, no matter the season.

Common Car Electrical Repairs

Common Car Electrical RepairsIf your vehicle needs some complicated but common car electrical repairs, bring it into our experts at Sundance Automotive Repair in Lakewood. Electrical systems are complicated and control everything in the car from the windows to starting the engine.

Let’s look at some typical problems you might experience with your vehicle’s electrical system.


If your car has trouble starting, it could be a defective component in the electrical system that’s draining your battery and stopping the starter from cranking the engine. You may notice the check engine light will be on in these circumstances.

Do you hear a clicking noise when you turn the key? If you do, it often means that the starter can’t get enough current flow in order to engage. Your starter may be the problem. If you hear a grinding noise while it’s cranking is may be caused by a bad starter or a flywheel ring gear.

The chance that the problem is the rotating electrical parts going bad increases if you have an older the car and higher mileage. Hard starting can also signal a problem with fuel injection delivery during cranking. Sometimes a regular fuel injection and throttle body cleaning will help get your engine started.


Your vehicle’s electrical system depends on the battery which stores the electrical energy for later use. You should replace a car battery every four years so your electrical system is always running at its best. Without a good battery, you may get stranded and need a tow. We can get you a new battery and recycle your old one. We can inspect your battery tray and cable terminal ends and evaluate the battery’s charging and starting system.

Our team at Sundance can check your electrical system instead of just the battery because it could be a bad battery cell or alternator that isn’t charging properly and stopping the car battery from staying charged fully which shortens the battery life.

We can check your battery’s cables for corrosion and to make sure there is a tight fit at the terminal ends. Corrosion creates resistance that stops the power from flowing through the electrical system. If they are corroded, we will remove them and clean them.


Do your headlights or brake lights dim? If so, it could be an indication of a charging malfunction, resistance in the electrical system, loose wires, a severely discharged battery or a problem with the alternator belt. A loose or cracked alternator belt can stop your alternator from working efficiently and maintaining the battery’s voltage.

It could also mean you have low system voltage. If that happens and the voltage drops below a certain level, then your safety systems like traction control may disable and eventually, your car will stop running altogether.


If you smell the odor of melting plastic or electrical insulation bring your vehicle into us. Every electrical circuit can carry a certain amount of current and when a wire or component shorts, the circuit draws more power than it can handle. We can fix these vehicle electrical problems before they become dangerous.


If a fuse is blown then an electrical device or wiring has drawn too much current. We need to find the problem that caused it to blow, then replace the fuse.

If you have any of these problems, we can take care of these common car electrical repairs, just bring it into our experts at Sundance Automotive Repair in Lakewood. Our goal is to handle problems before they become bigger problems.

Car AC Repair

car ac repairIf you need car AC repair or a performance check, bring your car, truck or SUV to our expert technicians at Sundance Automotive in Lakewood. We’ll help you get it taken care of before the heat of summer descends on Colorado, because there’s nothing worse than sitting in traffic and dripping with sweat while your fellow commuters are relaxing and enjoying their ice-cold AC.

Of course, the best protection from problems is prevention, including a complete air conditioning performance check by our technicians. If you skip your check-up, here are just a few problems that you may encounter, all of which require car AC repair.

Repair Problem 1: Black Death

Auto technicians describe what they call Black Death, which is the breakdown of the refrigerant-lubricant causing extreme wear inside the air conditioning compressor. This sends metal particles through the system, contaminating other components. When this happens, it will at least require a complete flushing and perhaps a replacement of the air conditioning system.

How it happens. It’s normal for a small amount of wear to occur inside the compressor because of the contact with all the moving metal parts. The refrigerant-lubricant reduces wear. The amount of wear increases when the compressor is operated on a low charge of the PAG (Poly Alkaline Glycol) oil or mineral oil which is recommended for specific air conditioning systems.

When an air conditioning system is operated under low-charge conditions, loose wear particles are circulated throughout the system which can produce damage. They lodge in various system components and frequently impede or even block the flow of the refrigerant-lubricant. If a new compressor is installed in a system that hasn’t been completely flushed, it’s likely that the new compressor will fail again, which could void the warranty and be a very expensive repair.

For the air conditioning system to be able to remove heat from the car’s interior, all the main system components need to be working and efficient. The contaminants from Black Death reduces the system’s efficiency and will eventually lock up the compressor or block the flow of the refrigerant-lubricant. Since refrigerant gives lubrication to protect the engine, if there is a breakdown with the refrigerant it will result in damage to the compressor.

The metal particles made during the compressor breakdown move through the rest of the air conditioning system, damaging the whole system. Symptoms of trouble include:

  • Your compressor is noisy during operation.
  • In turning the compressor clutch, you may feel hard spots.
  • The compressor may be totally frozen or locked up.
  • The orifice tube or the inlet and outlet ports may show signs of contamination when the hose manifold is removed.

Depending on how bad the damage is and the extent of the contamination from Black Death, car AC repair will require flushing the air conditioning system with solvents. During the flushing process, segments of the system have to be cleaned individually.

A new compressor, accumulator/drier and expansion device needs to be installed after the flushing. There are other components that also require replacement, including an accumulator, manifold, liquid line, condenser and orifice tube.

The Black Death gunk bonds to the components in the system. It’s hard to flush out because it’s inside. A flush gun, attached to your air compressor is not powerful enough to get rid of the Black Death material from components. Even a closed loop flush machine isn’t always enough.

An expensive flush machine called the Rotunda is strong enough to break down the Black Death material into a flushable material. Many times, the best thing to do is just replace the whole AC system.

Repair Problem 2: Weak Airflow

If you notice your air conditioning has weak airflow, you should bring it to Sundance Automotive before any damage to your air conditioning system occurs. There are several reasons for weak airflow, including:

  • Mold or mildew is in the evaporator core caused from the residual moisture during the cooling process and air can’t reach your air vents.
  • A loose hose, usually the hose that supplies air to the blower unit.
  • The ventilation fan is broken.
  • Core case seals, blower house seals or evaporator core case seals have opened and compromised the system.

Repair Problem 3: Not Very Cold Air

If you notice that the air is too warm for air conditioning, let us take a look at it and provide car AC repair. It could be caused by several things, including:

  • A Freon leak from by a failed o-ring, seal, hose, or component.
  • A clogged expansion tube or refrigerant charging hose.
  • A failed compressor or compressor clutch.
  • A failed blower motor or blower motor resistor.
  • A failed or damaged condenser or evaporator.
  • A vacuum leak.
  • A broken switch, fuse, relay, control module, blend door or solenoid.

Repair Problem 4: AC Leaks

If your air conditioning system has a leak, it’s called an open system. If a leak isn’t repaired quickly moisture will enter the system and cause damage.

Here are some possible causes. When moisture and refrigerant mix, corrosive acids destroy seals and components, leading to a leak. Rubber seals and hoses can also lose their elasticity over time and break down allowing Freon to escape and moisture to enter your vehicle’s air conditioning system.

Once moisture is present, it can damage the accumulator, receiver or drier because these things remove moisture from the air conditioning system and break when they are exposed to a leak or a crack.

Repair Problem 5: Cooling then Warming

If your air loses its cool temperature quickly you could have a number of problems, including:

  • A clogged expansion valve.
  • A faulty compressor clutch.
  • A blown fuse.

Repair Problem 6: Bad Smells

If the air smells like a musty gym locker several things could be causing it, including an old air cabin filter. It could also be a moldy evaporator case. If water sits in the evaporator case because the case’s drain is blocked, mold can grow.

If you need car AC repair or a performance check, bring your vehicle into our technicians at Sundance Automotive in Lakewood. Get it taken care of before the hot summer comes. It may save you from problems like Black Death, weak air flow, a leak, warm air, and a bad smell.

What is My Car’s TPMS system?

What is My Car’s TPMS system?Good tires that are inflated correctly are vital for your safety. If you have a newer car, you’re in luck because it probably has a tire pressure monitoring system or what is known as a TPMS. You might wonder what is my car’s TPMS system? A TPMS is an electronic system located inside your tire that actually monitors the air pressure in your tires. Our Sundance Automotive technicians in Lakewood can make sure your tires are inflated correctly because having the correct tire pressure is important for braking, gripping the road, and the longevity of your tires.

If your tires are incorrectly inflated, the TPMS will send an alert with a warning light on your car’s dashboard. If there is a steady warning light, you need to get your tire pressure checked, but if the warning light is flashing, it means your TPMS may not be working right.

According to a Popular Mechanics article, a Department of Transportation study from 2001 reports that 60 to 80 percent of cars on the road are driving with tires that are under-inflated by as much as 10 percent. It also reports that 20 to 50 percent of cars have tires that may be under-inflated by as much as 20 percent. But here’s what you want to consider, your TPMS warning light will only go on when your tire pressure is less than 25 percent. And that may be too late. When it gets to that level, it will reduce your car’s fuel economy, not be able to grip the road (particularly in wet conditions), and the tires may run hotter. So even if your car has TPMS, you should bring it to our auto technicians to make sure the tires are inflated correctly.

The Popular Mechanics article also explains how your vehicle may have either a direct-reading or an indirect TPMS. Let’s take a look at the difference between the two.

Indirect TPMS

An indirect TPMS system uses software and readouts given by the car’s wheel-speed sensors from the vehicle’s antilock brake system. If all of the tires are inflated properly, they will rotate the same number of revolutions. However, if one tire rotates more, then the sensor knows it has a shorter rolling radius because of low tire pressure. This system is cheaper because it just has a display on the dash and some extra code in the operating system.

This can be a concern if your tires are unevenly worn, or if you replace only two tires instead of all four tires. You can try to reset the system to allow for wear when all the tire pressures are correct. TPMS warning lights can be triggered after a normal tire rotation, or if you’re replacing tires of a different size from the previous ones.

The TPMS senders are generally attached to the valve stem or the wheel’s drop center. The metal stem of the sender is usually made of aluminum which can strip the threads if its overtightened. So, bring your vehicle into our trained auto technicians so the senders don’t get damaged from tire mounting machines.

Direct-Reading TPMS

This type of TPMS comes from a more expensive technology that is used to monitor tire pressure, however, it is usually more effective.

These battery-powered sensors are mounted inside the tire and communicate with the TPMS through small antennas in each wheel well. They receive a tire pressure reading and transfer the message to the in-car display. The individual senders have a unique serial number that transmits it to the vehicle so it reads the right tires. Some vehicles even have a sender on the spare tire.

You should resynchronize the TPMS if you rotate the tires or you get a flat. You will need a special tool to communicate with the vehicle and the senders. That’s another reason why it’s important to let us do it for you.

Want to know about maintaining proper tire pressure and driving safely? Bring your car in and our Sundance Automotive technicians in Lakewood can answer your questions about what is my car’s TPMS system more fully and examine your tires to make sure they are inflated correctly. It’s an important safety check that shouldn’t be forgotten.

How a Radiator Flush Helps Your Engine’s Cooling System

How a Radiator Flush Helps Your Engine’s Cooling SystemToday, Sundance Automotive Repair in Lakewood wants to share with you how a radiator flush helps your engine’s cooling system. If you didn’t know, cooling systems fail more often than any other mechanical system and it’s usually because of neglect. Lucky for you, our ASE-certified technicians have the knowledge, experience, and proper cooling system equipment to quickly diagnose and repair your vehicle’s cooling system problems.

Why do you need to maintain your cooling system?

Your cooling system is not maintenance-free. In many vehicles, when coolant breaks down, it can cause rust. These rust particles can then become electrically charged and cause the coolant to become highly corrosive. This sometimes results in major damage to the engine and cooling system. To avoid such a catastrophic issue, your system needs to be flushed.

Why are antifreeze leaks bad?

If you notice an antifreeze leak, you need to pay attention. If you’re parked on the street or your driveway the leaking antifreeze could get into the storm drain and make its way into your town’s water supply. In addition to the health and environmental problems, a leaking radiator can also cause a cooling system failure. If it’s the radiator that has a leak, it can burst open and spew the rest of the coolant. If it’s a hose leak, it may cause the hose to blow out. Our technicians’ advice is to fix the leak early to prevent dealing with a bigger, more expensive problem down the line.

What do you do when you see your car is overheating?

Cooling an engine involves coolant flow and airflow across the radiator. So instead of pulling over and turning off the engine if your car overheats, you should increase your car’s speed to allow more coolant flow and more airflow. Believe it or not, another thing you can do if your car overheats is to turn your heater on full-blast. Yes, it really works, because the heater is basically a cooling coil that dumps heat from the engine inside the cabin of the vehicle.

Follow the manufacturer’s recommendations on antifreeze.

You should always check your vehicle manufacturer’s warranty because sometimes your warranty is void if you don’t use the recommended antifreeze. It also needs to be filled to the correct specifications. If you live in a cold weather location, your antifreeze can actually freeze if it gets cold enough. One solution is to mix the antifreeze with water. This actually lowers the risk of your coolant freezing. You should also keep the coolant level full.

Because your coolant will eventually break down you will need to put a coolant flush on your maintenance schedule. Our Sundance Automotive Repair specialists can help you.

What is really involved in a cooling system flush?

A cooling system flush, or what is sometimes called a radiator flush, completely removes the fluid from the coolant system. If it’s a normal cooling system service, the coolant is drained and then replaced, but this process only removes about 50 percent of the fluid from the radiator. It also doesn’t help clean out the built-up scale deposits and debris.

Your vehicle may need a full flush, which uses specialized flushing equipment to fully clear the system of fluid. This is known as a cooling system transfusion. Any accumulated water and the coolant are flushed out of the system.

During a coolant flush, the built-up contaminants in the coolant system are also removed. This means all the scale deposits, rust, and particulates are completely cleaned out and the entire system is cleaned out with an engine-safe detergent and protective conditioner.

Bottom line, your cooling system is a complex component that ensures your car, truck or SUV runs smoothly. It’s important to keep your cooling system well-maintained and full of high-quality coolant to protect your car against corrosion and future engine damage. It’s also vital to have a coolant flush service completed for true protection and to keep your car running longer.

When you come to Sundance, our automotive technicians will use flushing chemicals to scrub the coolant system clean. Then additives and a conditioner are added to prolong the life of the system and protect against corrosion. Lastly, the system is refilled with fresh, premium coolant.

What are the benefits your vehicle receives from a coolant flush?

The biggest benefit is removing old coolant before it has a chance to become acidic. Coolant breaks down over time. Antifreeze specifically can become acidic if it is not replaced periodically. If not properly serviced, old and broken down coolant can cause other parts of the vehicle to break down, wear prematurely, or cause corrosion.

A coolant flush also helps lengthen the life of your cooling system. The additives and protective lubricants in the coolant are designed to protect the water pump and radiator. As these properties age, they’re less able to do their job. By flushing the system, you’re making sure clean additives are flowing through your engine.

When do you need a cooling system flush?

Check your manufacturer’s recommended service but generally, your cooling system should get a full maintenance service every 30,000-60,000 miles. We will make sure you get a complete cooling system test. Based on those results, we may recommend a complete system flush.

At Sundance Automotive Repair, our goal is to offer the best services available at affordable prices so you stay safe and your car runs well. Our team of experts offers these cooling system services and repairs for foreign and domestics vehicles, cars, trucks, and SUVs:

  • Complete cooling system diagnostic
  • Repair and service cooling systems
  • Replace thermostat
  • Radiator service

  • Replace antifreeze
  • Replace radiator hoses and fan belts

Now you know how a radiator flush helps your engine’s cooling system. So, bring your car, truck, or SUV into Sundance Automotive Repair in Lakewood. Our ASE-certified technicians take care of your cooling system so it can keep working well for the life of your car. Putting in a little bit of maintenance really does go a long way.

Synthetic Oil Change For Your Car

Synthetic Oil Change For Your CarIt’s important to follow the manufacturer’s recommendations for the type of oil and frequency of oil changes in order to keep your car running in prime condition. However, if you’re not sure whether to go with a conventional or synthetic oil change for your car, just visit the experts Sundance Automotive in Lakewood and we’ll point you in the right direction.

Synthetic Oil

Are you wondering what synthetic oil is? Synthetic oil is man-made. Sometimes it uses a petroleum base that’s been modified and sometimes it is totally synthesized from other materials (full synthetic oil).

Synthetic oil must pass stringent tests. It is made from chemical compounds that offer better protection and performance for your car’s engine than conventional oil, including less evaporative loss, a higher viscosity index (resistance to thinning as temperature rise is the viscosity index), greater resistance to oxidation thermal breakdown and sludge problems.

Synthetic also offers better performance in extreme temperatures. It flows more freely at freezing temperatures and provides greater chemical stability at high temperatures. It won’t easily evaporate or break down from the heat of your vehicle engine. This allows it to resist turning into sludge, which can cause engine problems.

Costs More

Yes, a synthetic oil change for your car will cost more than conventional oil. It goes through a more involved manufacturing process, which makes the price higher. So if an oil change with conventional oil costs around $20, then an oil change with synthetic oil would cost about $80. But consider that synthetic oil lasts longer, so you don’t need an oil change as often. If your car doesn’t need synthetic oil then conventional oil is fine.

Just be aware that certain manufacturers are using full synthetic oil in their high-tech engines. If your car maker requires you to use it and you don’t, it may risk damage to your engine damage and void your vehicle warranty. Corvettes and many Mercedes vehicles come with synthetic oil as a factory fill.

Synthetic Blend Oil

There is also a synthetic blend oil. This is a blend of synthetic and conventional oils and is between them in price and protection. Synthetic oil is more slippery than conventional oil and that means less friction in your engine. This allows your engine to run cooler, have less wear, and last longer. It can also give you a boost in power. If you do a lot of towing, off-roading, or severe use driving like in heavy traffic, you might want to consider using a synthetic or synthetic blend.

Oil Filter

Don’t forget to get an oil filter specifically built for the longer lasting service life of synthetic oil.

The rule of thumb is to always follow your car manufacturer’s recommendations on what type of oil to use and how often to bring it in for a change. It’s one of the most important things you can do to ensure better vehicle performance and greater longevity. So, when it’s time for a synthetic oil change for your car, come to Sundance Automotive in Lakewood. We’re the oil change experts, whether conventional or synthetic. Call or contact us today for an appointment.

Vehicle Winterization Tips

Vehicle Winterization TipsIt’s December and that means cold weather in Colorado. It also means it’s time to bring your car into Sundance Automotive in Lakewood to get it ready for winter if you haven’t already. Our technicians know the best vehicle winterization tips. A article offers some suggestions as well, so let’s check those out as well.

It’s Time to Replace and Refill All Fluids

Your car’s fluids are important. We will check them and fill them up or replace them so your vehicle can run it’s best in the cold weather, including oil, coolants, and wiper fluid.

  • Oil: Switching to a thinner oil may be a consideration if you live where the temperature dips below freezing. We can take a look at what kind of car you have and where you live, particularly if you spend any time in the mountains, and make some suggestions for you.
  • Coolant: The right antifreeze will help prevent fluid from freezing in your radiator.
  • Wiper Fluid: When the winter storms hit you will want your freeze resistant wiper fluid to be filled up so you can keep your windshield clear. 
  • De-icing: Sometimes it’s so cold it can freeze car door locks. What if you can’t get the door open or your key breaks off in the lock and you don’t have any warm water to help melt it? You might want to get glycerine to use as a de-icer, just don’t keep it in your car where it can get locked in.

Don’t Forget to Check Your Tires

When it comes to vehicle winterization tips, your tires are very high on our list. You need to make sure your tires are in good shape and possibly replace them with something more conducive to the cold. 

  • Pressure and Tread: When the roads get slick from snow and slush you need to make sure your tires are not too worn out and the air pressure is not too low in order to get the best traction. We will check your PSI and make sure your tires are inflated properly.
  • Snow Tires: You might want to consider getting snow tires if you live in an area of Denver metro that may not see snow plows come through often. Snow tires increase traction in the snow and keep you safer on the road. You could also go with snow tires with studs, just remember to change them when spring comes. We also carry all-season tires that can function in all weather.

Can Your Battery Handle the Cold?

As you know, your car’s battery is very important for starting your car in the winter and battery capacity is reduced when the weather is cold. We’ll take a look at your battery, check the cables for cracks and breaks and make sure the terminals have no loose connections. We’ll also look at the battery fluid level and fill it up if needed. Finally, we’ll test the battery’s level of charge.

For more vehicle winterization tips, as well as last-minute preparations, simply bring your car, truck or SUV to the experts at Sundance Automotive in Lakewood. We’ll provide the right fluids and recommend the right tires. Need any other work or repairs? You got it. Call or contact us today for an appointment.

Brake Repair and Disc Brake Maintenance

Brake Repair and Disc Brake MaintenanceHave you had your brakes inspected lately? A regular brake check should be on every car’s maintenance list. If you need brake repair and disc brake maintenance, bring your vehicle to our certified technicians at Sundance Automotive in Lakewood. We can inspect, diagnose and repair brake related problems for any car, truck or SUV – foreign or domestic.

The reason for brake repair and disc brake maintenance is obvious, your car needs to be able to stop, especially in case of emergency. But, how much do you know about this crucial system? Here we’ll give you a quick look at its inner workings and parts so that you can better understand your vehicle.

How Disc Brakes Work

The wheel hub keeps your wheel on the vehicle. Inside the hub, the brake disc (also called the rotor) turns with the wheel as you drive. Straddling the disc is the caliper which houses pistons that apply the necessary pressure to the brake pads. So when you step on the brake pedal, these pistons cause the pads to clamp down onto the disc and slow down the wheel. When the brakes are released, the pistons retract, removing the pads from the caliper.

Of course, there’s a lot more to a car’s brake system than this, as well as another vehicle braking system known as drum brakes. For a complete dissertation on brake repair and disc brake maintenance, come chat with a tech at Sundance Automotive in Lakewood, and they’ll talk your ear off.

How Brakes Wear Out

Your vehicle’s brake pads start to wear the moment you use the brakes. So, eventually, the pads will need to be replaced. Newer vehicles typically have sensors that will trigger a dash warning light when it’s time to swap out your brake pads.

If you don’t replace your pads, the metal parts of the brake will grind against the brake disk/rotor and carve grooves in the surface. While we may be able to smooth it out on a lathe, deep grooves and a warped or cracked rotor will need to be replaced. Like many auto repairs, the longer you wait, the more damage you create and the more expensive it will be for brake repair and disc brake maintenance.
