Signs of Car Engine Trouble

Signs of Car Engine Trouble Sundance Automotive DenverKnowing the signs of car engine trouble can save you a great deal of money and time. Here at Sundance Automotive in Westminster, we want to help you save your engine so that your car troubles won’t break the bank.

Check Engine Light

Though a check engine light can mean so many things, it is never a good idea to ignore it. Hooking your car up to a scan tool is an easy way to quickly determine what the problem might be. Sometimes the trouble is something easy like the gas cap is not screwed on properly, but your check engine light can be a sign that something has gone much more wrong and needs immediate attention.

Jerking, Surging, Misfiring, or Hesitating

When your engine is functioning properly, everything runs smoothly. If your car surges or misfires, it may be a sign that your engine is running too hot. If there is hesitation when you press on the gas, you could have trouble such clogged fuel lines, bad spark plugs, or dirty air filters. Additionally, if your engine is revving high when it should be idling or if you experience sudden acceleration, you have an issue that should not be ignored.

If you are experiencing signs of car engine trouble, contact us at Sundance Automotive to make an appointment. We can get your engine running right so that you can avoid a more costly problem.

Odd Noises

If your car has started making odd noises, it is important to get them checked out right away. Grinding, tapping, or popping sounds are among the noises that can mean your engine is experiencing a problem. Try to track down where the noise is coming from as well as when it seems to occur so that you can relay specific information to your mechanic.

Strange Smells

It is never a good sign if a strange smell has made it to your car’s interior. Odd smells can be an indication of leaking from what is normally the closed loop system of your engine. Rubber and exhaust smells can also spell engine trouble. It is best to get those unexplained smells check out directly.


Smoke is never a good sign and most people understand that. If you notice smoke that looks like it is blue, this likely means you have an oil leak somewhere, whereas white smoke from your tailpipe means that antifreeze or water condensation is mixing with your fuel. To avoid overheating or other more significant problems, get your car to a mechanic quickly.

Excessive Oil

If you need to provide your vehicle with more oil regularly, you could have an oil leak and a potentially more serious problem as well. Getting your vehicle checked is a good way to avoid more trouble.

If you are experiencing signs of car engine trouble, contact us here at Sundance Automotive in Westminster for an appointment. We can get your problem solved and get you back on the road quickly with a car that is running properly.

Basics of Car Brake Repair

Basics of Car Brake Repair Sundance Automotive DenverKnowing the basics of car brake repair can be helpful when you have a brake issue. Here at Sundance Automotive in Westminster, we want to help our customers better understand their brakes. There are five main components of your brakes, knowing a bit about what each one does can help you understand when you have a problem.

Brakes Lines and the Master Cylinder

Today’s brakes work hydraulically. This means fluid is used to transfer the power of your foot on the brake pedal to the actual brakes on your wheels. The master cylinder is where it all begins. If your master cylinder is not functioning properly, it may not be able to push fluid to your brakes. This is why checking your brakes lines and master cylinder for damage is a good idea.

Calipers, Pads, and Rotors

The calipers, pads, and rotors all work in conjunction with each other to bring your vehicle to a stop. When you press your brake pedal, the master cylinder pushes fluid to your brake calipers. The calipers squeeze together, placing pressure on your brake pads. When the calipers press together, the brake pads clamp down on your rotors which in turn causes your car to slow down. If your calipers are damaged they may not be able to squeeze together effectively.

It is also important to check your brake pads for wear. If your brake pads are worn down, they will not be able to connect smoothly. This uneven connection can damage your rotors and these can be expensive to repair.  Most brake pads today include wear indicators. These indicators squeal as a way to let you know it is time to get your pads replaced.

Stick to Your Maintenance Schedule

Use the guidelines in your owner’s manual to make sure regular maintenance and checks are performed on your brake system to avoid costly repair. If you are unsure about replacing the pads or brake fluid, you can stick to the basic guideline of checking every 12,000 miles.

If you are in need of brake system maintenance on your vehicle, contact us at Sundance Automotive to schedule an appointment. We can make sure your brakes are working properly and effectively.

Maintenance Cost

Regular maintenance is one of the basics of car brake repair and an excellent way to save you money. Getting your pads and fluid replaced regularly is much more cost effective than needing to replace the rotors or a full brake system repair. Preventative maintenance really can save you a great deal of money over time. Servicing your brake pads and replacing the fluid can cost you less than $100 (depending on the specific service needed) while needing rotor replacement may be ten times as much. It is an excellent idea to keep to the maintenance schedule for best results.

The basics of car brake repair are fairly straightforward. If you need your brakes serviced, contact us here at Sundance Automotive in Westminster for an appointment. We will help keep your brakes in good shape to help you avoid more expensive repairs.

Causes of a Failed Emissions Test

Causes of a Failed Emissions Test Sundance Automotive DenverToday, the car experts at Sundance Automotive in Westminster want to cover the causes of a failed emissions test. This assessment checks for pollutants produced by the engine of a car. When a vehicle fails the test, it can be a source of frustration and even worry. We get a number of questions from stressed out customers who bring their vehicles in after failing this important test. However, knowing the common causes can help you better understand what may need to be done to get your vehicle to pass the emissions test.

Emissions Test Basics

Generally, in an emissions test, there are three different vehicle inspections that could point to a wide variety of causes of a failed emissions test.

  • The Acceleration Simulation (ASM) checks for dangerous gases like carbon monoxide.
  • The On-Board Diagnostics (OBD) monitors the performance and status of the emission control equipment and the ignition system.
  • The Two-Speed Idle (TSI) tests emission gases on older vehicles (those vehicles from 1995 or before).

Gas Analyzers

There are five gases that are monitored during emissions tests: carbon monoxide, carbon dioxide, hydrocarbon, oxygen, and nitrogen oxides. A gas analyzer is put in a vehicle’s tailpipe to measure the emission of these gases. There are also portable gas analyzers which use infrared to measure the temperatures of the various gases. Additionally, diesel analyzers are used to monitor emissions for diesel engines.

DLC Scanner

The Diagnostic Link Connector (DLC) Scanner works with a Diagnostic Link Connector monitor. Sometimes a vehicle needs to be driven a distance in order for all the monitors of the DLC Scanner to work properly. This means that a car owner will be asked to drive an additional distance before returning so that the DLC Scanner can work properly.

Additionally, the DLC will check if the Malfunction Indicator Lamp (MIL) light is on or off. The MIL light is a signal warning for problems and malfunctions in the engine so it is very important that it be in proper working order and good condition. The MIL light uses the Check Engine Light (or other warning light) to help determine the engine’s status. Usually, the MIL light is turned on when the vehicle’s engine is causing issues that result in excessive emissions. The DLC Scanner also gets any fault codes that the vehicle currently has.

Emission Standards in the US

The US has different standards for each gas that is being monitored. Here are the levels that are used in your car’s emissions standards tests.

  • Hydrocarbons—In the atmosphere, hydrocarbons react to the nitrogen oxide and sunlight. The combination produces ozone. On the ground, ozone is a part of smog which is one of the worst offenders of air pollution. Smog can cause breathing problems, damage lungs, irritate eyes, and has even been found to cause cancer.

The amount of hydrocarbons from a passenger car that is a transitional low emission vehicle (TLEV) must be less than .156 g/mi. An ultra-low emission vehicle (ULEV) must have a level that is lower than .055 g/mi.

  • Nitrogen oxide—When oxygen and nitrogen combine a high pressure, nitrogen oxide is formed. Engines can be very high producers of nitrogen oxide. Nitrogen oxide is the primary cause of acid rain. The maximum nitrogen oxide level for emissions is .6 g/mi for a TLEV and .3 g/mi for a ULEV.
  • Carbon monoxide—When fuel is not completely oxidized to carbon dioxide, carbon monoxide forms. Carbon monoxide is toxic to human beings and it is one of the primary emissions from vehicles. The maximum amount of carbon monoxide for a TLEV is 4.2 g/mi and for a ULEV the maximum amount is 2.1 g/mi.
  • Carbon dioxide—This gas is one of the main greenhouse gases that contribute to the increase in the earth’s overall temperature.
  • Additional emissions—Some of the emissions are created by evaporation that occurs at higher temperatures. For example, gas vapors are vented at higher temperatures. For emissions testing, the emissions of gas vapors must be less than 2.0 g/test hour.
  • Additional standards—Each state has additional standards that must be met for emissions tests.

Common Failure Reasons

There are several causes of a failed emissions test. Here are a few of the more common reasons. If you need to have an emissions test or need a repair to pass your emissions test, contact us at Sundance Automotive in Westminster to make an appointment.

  • Fuel metering specification. Your vehicle could have a faulty computerized engine control, fuel injections unit, or carburetor that can cause your vehicle’s fuel metering to not meet specifications.
  • Faulty oxygen sensor. A faulty oxygen sensor is very common and can lead to other problems such as higher emissions, overheating, and loss of acceleration.
  • Defective ignition system. Generally, this means your car is emitting high amounts of hydrocarbons. It can be an indication of defective spark plug wires, worn out spark plugs, a worn distributor cap, or an ignition-timing problem.
  • Vacuum leaks. The MAP sensor not working properly can lead to a leak and be one of the causes of a failed emissions test.
  • Rich fuel mixture. A rich air/fuel mixture can be caused by a number of issues such as leaky injectors or excessive fuel pressure. This will cause high carbon monoxide levels as well as high carbon dioxide emissions.
  • Malfunction in the air injection system. This system reduces the emissions of hydrocarbons and carbon monoxide. The air injection system forces air into an engine’s exhaust. If this system is not working properly, the vehicle can emit large amounts of carbon monoxide and hydrocarbons.
  • Faulty evaporative emission control system. The evaporative emission control or EVAP system prevents gasoline vapors from being released into the atmosphere. Leaks in system hoses and vents are common reasons for this system to be problematic. It could also be related to a defective purge valve or a faulty gas cap.

Hopefully, now that you know the causes of a failed emissions test, you’ll be better prepared and a little less worried if and when your car experiences an issue. Most importantly, you can always bring it to Sundance Automotive in Westminster to get the repairs handled by the pros. Contact us today for your appointment and we’ll make sure your car aces the test next time around.

Does a Nail Puncture Require New Tires?

Does a Nail Puncture Require New Tires Sundance Automotive DenverNew tires can be expensive, so does a nail puncture require new tires? Here at Sundance Automotive in Westminster, the first step in answering this question for you is to perform an assessment. We’ll look at where the puncture is and how much damage has been caused before determining next steps. If a new tire is needed, you can trust our shop to give you a great price for quality tires and installation.

The Nail Location

If you're wondering does a nail puncture require new tires, it's all about location. Unfortunately, if a screw or nail has punctured the sidewall, you will need new tires. These types of punctures simply cannot be repaired. If the nail or screw is along the shoulder of the tire, that also will require a replacement. However, if the center of the tread is where the nail or screw entered, you are in luck, and we can provide tire repair services.

Exceptions that will typically require tire replacement:

  • Cuts, slices, or larger punctures, regardless of location
  • If your tire has been patched at some other time
  • Any tire that no longer has a tread depth of at least 2/32”

Leaking Puncture

If the puncture is slowly leaking or if it is not yet leaking at all, you should be able to drive it to the shop to get your tire repaired. If the air is quickly escaping, then driving on the tire is not recommended. You could wind up creating all new problems.

Put your hand on the area that is punctured and feel for air. You can also spray soapy water on the puncture. If it bubbles, air is escaping. You may even hear the air leaking. If you can hear the air escaping, you should not drive any further on the tire. Additionally, if your car has a tire pressure monitor, you may be able to see how quickly air is escaping by watching the monitor. Do not drive until you’ve performed an assessment and only found a slow leak.

Flat Tires

If your wheel appears to be resting on the fold or if your tire is clearly flat from a puncture, do not drive on it. If you drive on a completely flat tire, it will be damaged internally and the tire will need to be replaced regardless of where the puncture is. If you have a spare tire, you should change it before proceeding to a repair shop or tire store.

Your vehicle may be equipped with “run flat” tires. Run-flat tires are intended to support the weight of your car when your tire is flat or punctured. With a run-flat tire, you may not even realize that your tire has lost all its pressure. The sidewalls of run-flat tires have been reinforced so that the tire’s internal structures are not quickly ruined while driving with a flat tire. You can drive around 50 miles at a maximum of 50 mph, depending on your run flat tire. It is best to check the specifications on your tire to know for sure.

When You Can’t Drive on a Tire
  • Donuts or Space-Saver Tires

Donut tires or space-saver tires are much like run flats. They are not designed to travel very long distances. In general, an average space-saver tire or donut will also travel 50 miles at 50 mph. Just make sure you get to Sundance for tire repair or replacement services.

  • Spare Tires

Full-size spares are just like your normal tires so they can be driven any needed distance. You will still want to get the original tire replaced as soon as possible because it will not wear at the same rate as your regular tires. This can eventually lead to unsafe handling while driving your vehicle.

A Few Items to Note if You Have Tire Trouble

Not a DIY Project

Tire repair involves fixing the hole from the inside, as well as the outside. The wheel must be taken from the vehicle and the tire must be removed from the wheel. The process also involves special tools, so tire repair should be left to professionals. If you have a tire puncture that needs repair, contact us here at Sundance Automotive in Westminster. We can get the repair done and get you back on your way.


General vehicle warranties do not cover your tires. There are third parties that sell tire specific warranties. If you purchased one of these warranties, be sure to have proof of your coverage with you. New cars also offer tire insurance and warranties and insurance may be available to you when you purchase new tires.

Be Prepared

It is always best to be prepared for life’s little annoyances and a flat tire from a nail or screw can be quite frustrating. It is best to be prepared for such an event. First, it is important to know whether you have a spare, a replacement tire, or a run-flat. Finding out when you experience an issue can be a huge inconvenience.

Additionally, some cars have an air pump that may also be able to pump a fix-a-flat chemical. These chemicals have expiration dates and will not work on larger holes. Also, if left in your tire for an extended period, these chemicals can damage your Tire Pressure Monitoring System (TPMS) if you have one on your vehicle. If you know what you have with you ahead of an emergency, you will be better prepared for an actual emergency.

If your car is not equipped with a spare, you may want to carry one for such a situation. It is also good to understand how to use the equipment that is included with your car. Additionally, everyone should know how to change a tire in emergency situations, particularly, if you get stuck in a location without cell service. Though less and less common, there are many locations where you may not be able to get roadside assistance due to a lack of service or due to your location. It is important to prepare for a variety of situations.

Does a nail puncture require new tires? It all really depends. But if you need your tires repaired, contact us at Sundance Automotive in Westminster for your tire repair needs.

Understanding Your Shocks and Struts

Understanding Your Shocks and Struts Sundance Automotive DenverHere at Sundance Automotive in Westminster, we think understanding your shocks and struts is important to the overall care of your vehicle. Shocks and struts ensure that your ride is smooth and that your vehicle has greater stability. Here’s a guide to help you know more about your shocks and struts and to know when they are starting to fail.

What are They?

When your vehicle rides over a rough surface, your shocks and struts absorb the impact and dampen the effect of potholes and bumps. They prevent excessive bouncing, which is unsafe and can change the way a vehicle handles. Shocks and struts keep your vehicle on the ground by helping the tires stay on the road, which keeps everyone safer. This is why you need to replace your shocks and struts when they start to fail.

How are Shocks Different from Struts?

Understanding your shocks and struts starts with knowing more about each component.

  • Shocks are simple cylindrical parts that help absorb impact from your vehicle’s leaf springs. Their sole function is to keep your car from bouncing. Shocks are usually found in the front suspension while struts are usually in the rear.
  • Struts are a part of a complete suspension system and are encased in a complicated coil mechanism system. The struts absorb the shock from coils springs.

People use the terms shocks and struts interchangeably, but really the two parts are quite different. Trucks will frequently have shocks in both the front and rear suspension systems. Shocks are generally less expensive and simpler to replace. Struts can be much more complicated to replace.

If you want to get your shocks and struts checked, call us at Sundance Automotive. We will check out your shocks and struts for you and get them replaced quickly so that your vehicle doesn’t develop other issues and you can drive without safety concerns.

Signs of Failure

When it comes to understanding your shocks and struts, it’s important that you recognize a problem early so that you have an opportunity to get your car to a mechanic before there is real trouble. Here are a few indications to look out for:

  • Bottoming Out: If the rear end of the vehicle hits the pavement when the vehicle hits a rough spot, it is an indication that your rear shocks or struts are failing. If your car does this when you have extra weight in the trunk or extra people in the back seat, this is also a sign your shocks or struts may need replacement.             

Bottoming out can cause other problems for your vehicle if you fail to replace the shocks or struts. It can damage the body of your car, while further damage continues to the shocks and struts.

  • Forward Plunge: If your vehicle plunges forward when you come to a stop, this is another sign that your shocks or struts may be worn. This happens because your shocks or struts are not absorbing enough to help keep the weight of your car from traveling forward when you come to a stop.

The effect is hard on your brakes and is also a driving hazard. The forward plunge makes your vehicle more difficult to handle and steer. If you avoid caring for this issue promptly, you may find you will need to replace your brake pads as well.

  • Rock and Roll: If your vehicle rolls or rocks side to side when you turn corners, your shocks or struts may be to blame. You may notice that taking fast curves or turns is becoming more difficult as a result.

This is a potential hazard because the weight of your car could cause your wheels to leave the ground. This could, in turn, cause your car to roll. This is why you should have your shocks or struts replaced as soon as possible. Understanding your shocks and struts, as well as issues like this, are key to your driving safety.

  • Bumpy Ride: If riding in your vehicle seems particularly bouncy or bumpy, you may have a shock or strut problem. Rough roads and surfaces will feel bumpier while riding over them because the vibrations are not being absorbed. Additionally, your car will seem louder and your car will have decreased handling and tire performance. 
  • Unpredictable Handling: If your shocks or struts are failing you may find that you vehicle pitches unpredictably. Again, it is a good idea to get them checked out and replaced immediately. 
  • Poor Steering: If you notice that your steering is stiffer or noisier, this is another sign of a shock or strut problem.

You or your mechanic can check your shocks and struts for leaking. They can also be checked for visible damage. Unusual wear patterns on your tires can also be a sign that your shocks or struts may have issues. A tire cupping wear problem, for example, can be a wear pattern that indicates shocks or struts as the root issue.

Generally, shocks and struts may start to exhibit some of the above signs and symptoms around 50,000-60,000 miles. Depending on the type of driving you do and the general road conditions you experience, you may need to replace them sooner. Additionally, they may last longer if driving conditions are generally easier. Understanding your shocks and struts will help you better determine when to bring your car or truck for repairs.

Don’t Do It Yourself

While shocks are fairly easy to replace, you may think you could take care of the strut replacement as well. This is not a job that is generally recommended for a do-it-yourself job. The spring that encases the strut requires special machine compression to perform any repairs or replacement. Trying to do this yourself, with the wrong equipment especially, can result in serious injury.

Understanding your shocks and struts is an excellent way to better understand caring for your vehicle. If you need to have your shocks and struts inspected, repaired or replaced, contact us here at Sundance Automotive in Westminster. We can take good care of your vehicle, so you are safe when you are on the road.
