Simple Answers: Water Pump

by

The cooling system in an engine has five components:  the radiator, the radiator cap, the hoses, the thermostat and the water pump.  The water pump is literally the heart of the system.  Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.

The water pump is driven by a belt, chain or gear and only operates while the engine is running.  It has a limited life span and sooner or later will have to be replaced.  You can check your owner’s manual to find out how long your water pump should last.  Some can fail at only 40,000 miles, but almost all of them fail by 100,000 miles.

Water pumps can fail in two ways; they can spring a leak or their bearings fail.  Leaks can come from a cracked pump but usually develop at the gasket where the pump attaches to the engine.

If you hear a low-pitched grinding sound coming from the water pump, it’s time for a new one.  If you see coolant leaking in the area near the pump, it needs to be replaced.  Also, coolant on the driveway could indicate water pump failure.  Many water pumps aren’t visible because they’re under a plastic cover, so you may have to take your vehicle to an auto repair shop to know for sure if the water pump has failed.

If your water pump is run by the timing belt, then it should be replaced when you replace the belt.  Most timing belts need to be replaced at around 60,000 to 90,000 miles.  The labor for replacing a timing belt is about the same for replacing a water pump, so it’s cost-effective to take care of them both at the same time.

Also, if your water pump develops a leak (if it’s powered by a timing belt), you have to replace the timing belt as well since contamination by coolant fluid damages the belt.  It just makes sense for drivers to replace both of these parts whenever either one needs it.

Replacing a water pump is a car care issue that almost all of us face eventually.  They don’t last forever.  On the other hand, we can extend the life of most of the components of our vehicle through preventative maintenance.  Just as exercise and diet keep our heart healthy, regular inspections and fluid changes will keep our vehicles healthy.

Fuel Saving Tip: Check Engine Light

by

How long have you been enjoying the romantic glow of your Check Engine Light?  Hey, it isn’t there to create ambiance in your vehicle;  it’s a warning  that says something is wrong.

Fuel saving tip:  Many conditions that cause the check engine light to come on can affect your fuel economy, some very dramatically.  In newer vehicles it might be a problem with your gas cap not being screwed on tight enough (or a worn gas cap), causing the vehicle to fail the self-diagnostic evaporative emission test.  Always make sure you tighten your gas cap until it clicks.  A loose gas cap can cause a false sensor reading that will make the check engine light come on.  So if you verify that the gas cap is tight and that’s the problem, the light will turn off and everything will be fine within one or two days.

We advise drivers to resist the temptation to have someone “clear” the codes to turn off your vehicle check engine light.  This erases important diagnostic information that your service technician needs to diagnose the underlying problem for the check engine light or any other pending problems that may be stored in the computer.

So if your date’s eyes are smoldering in the reflected glow of the Check Engine Light, take this fuel saving tip and bring it in and have us check it out.

Springtime Vehicle Maintenance

by

Springtime is the perfect time to go through a vehicle maintenance checklist and get your car ready for the months ahead.  We’ve put this one together so you know what should be checked out.

  • Regular oil changes are very important for vehicle maintenance.  Clean oil in the engine keeps your vehicle running smoothly, so if it’s been a while, now is the time to change it.
  • Your vehicle’s cooling system needs maintenance.  Not only does it keep the engine from overheating but it also keeps it from freezing.  And since we experience springtime weather that can have both extremes, it’s important to have the system flushed and replaced with fresh coolant.
  • The terminals and cables on your battery should be inspected for wear or damage.  The battery fluid should also be checked along with the batteries ability to hold a charge.  If you’ve had the same battery for 4 years or more, you might want to have it replaced.
  • The tires on your vehicle should be checked to make sure they are in good condition and will provide the proper traction you need for springtime (rain, snow) driving.  Checking for proper tire pressure is another thing that will need attention.
  • Windshield wipers should be inspected and replaced if they are worn out and also refill the washer fluid reservoir.  With spring storms and dirt on the roads, sometimes we use our wipers more often than we thought we would.
  • If your car was built in the last decade, chances are good it has a cabin air filter.  This filter needs to be checked because it screens out dust and debris out of the air that’s entering your vehicle’s passenger compartment.  To improve the quality of the air you breathe while you drive, your cabin air filter should be changed.
  • Finally, the brakes on your vehicle should be checked.  If you haven’t had them checked in the last six months, now is the perfect time, because there’s no perfect time for the brakes to fail.

Vehicle maintenance can and should be done all the time, but if you haven’t started yet, springtime can be the perfect time for a new beginning.

Spark Plugs

by

Good news!  The days when drivers had to change their spark plugs every couple of years has ended.  Back in the day, spark plugs really did wear out that often.  Now, a couple of things are different…

First, spark plugs have a better design and are made of better materials that last longer for drivers.  The second reason spark plugs used to have to be changed more often is because carbon deposits would build up in them when fuel wasn’t burned completely and foul them up.  But with modern engine management controls that doesn’t happen as often.

Engine control computers precisely time when fuel is injected into the engine and when the spark plugs fire.  Unless something is wrong, spark plugs just don’t misfire as often now.

Electricity from the battery goes into a coil that allows power to build up to anywhere from 12,000 to 45,000 volts, depending on the vehicle.  The engine management computer tells the coil when to release the power to the spark plug.  The electricity travels through a wire from the coil to the spark plug.  At the tip of the plug, a spark jumps between two electrodes and ignites the gas in the combustion chamber.

Some engines have more than one coil.  Coils wear out and need to be replaced occasionally.  Also, spark plug wires can wear out and need to be replaced.  Modern engines in vehicles are delivering more power and better fuel economy all the time.  That’s largely credited to fast engine control computers, advanced sensors, electronic ignition and improvements to the lowly spark plug.  It will be interesting to see where future developments take us.

One last thought…it’s important to have the right kind of spark plug for your vehicle.  Because engines are designed to run with different internal temperatures, spark plugs have different designs that work properly within those temperatures.  Your service adviser at Express Car Care will be able to get the right plugs for your vehicle and be able to advise you as to when you should replace your spark plugs as well.

Tire Service in Denver

by

For most people buying tires can be a big deal, so play it safe and consult with your friendly and knowledgeable tire professional about the proper size, type and grade for your driving needs.  He can help you balance load requirements, performance, durability and cost.

It’s always best to replace both tires on the same axle when purchasing new tires, in order to keep the rolling diameter as close as possible.  Drivers with four-wheel drive vehicles should replace all four tires at the same time because they can run into problems if the tires have different rolling diameters due to wear or different types of tires.  Four-wheel drive vehicles should have all tires very close to the same rolling diameter to avoid binding and wheel hop between the front and rear axles.

Tire manufacturers also recommend that if you are buying just two new tires that they be installed on the rear for safer slippery road traction – regardless of which wheels drive the vehicle.  Express Car Care has you covered for all of your tire service in Denver needs including tire repair, tire mounting, and wheel balancing.

Simple Answers About Alignment

by

Question:  How do I know when I need a wheel alignment?

Express Car Care Answer:  When Denver drivers wheels are properly aligned, they point in the same direction.  When they are out of alignment, most drivers notice a couple of things.  First, the vehicle pulls to one side when driving.  It can be slight or pretty severe.  If your wheels have been out of alignment for a while, you’ll also start to see uneven tire wear – the shoulder on either the outside or inside of the tire is worn down more than the other.

There are many steering and suspension components that are joined together.  Everyday driving can cause a drivers wheels to go out of alignment over time just from the joints loosening up.  That’s why a simple alignment check is recommended every couple of years.  Depending on where you live or the conditions you drive in ( off-road driving, harsh winter conditions, poor pavement, etc.) an alignment inspection every year may be necessary.

Suspension and steering components wear over time as well, which can lead to alignment issues for drivers.  Of course, hitting a curb or pothole can knock a wheel out of alignment or damage a steering or suspension part.

Your friendly and knowledgeable service adviser will check your tires for uneven wear.  The type of wear provides clues to what might be wrong.  Parts located under the car are inspected for wear or damage.  An alignment machine will provide a reading of how each wheel is aligned.  The reading is compared with the alignment settings and then makes the necessary adjustments and repairs to bring your wheel back into alignment.

Due to the size of our shop, we don’t have the equipment to provide alignment service, but we can recommend quality shops that do provide this necessary service.

Putting off a wheel alignment can be dangerous because of tire wear, a bad alignment can chew through a tire pretty quickly.  If you see uneven tire wear, or if your steering wheel is off center, or your vehicle pulls to one side, ask your service adviser about getting an alignment check.

Finding Vehicle Recall Info in Denver

by

No matter how well they’re made, vehicles will have design or manufacturing problems.  And when the government thinks a problem is  really serious, they require the manufacturer of the vehicle to issue a recall notice and to repair the vehicle at no charge to the owner. The manufacturer has to try to contact everyone who owns that type of vehicle so they can get the recall work done.

These recalls always affect the safety of the drivers, so Denver residents should always take them seriously.  It’s not a difficult process to see if a vehicle has a recall.

The US government has links on its websites, such as http://www.nhtsa.gov 

There are many websites with free recall information and searches. To name a few:   carfax.com, autobytel.com and dmv.org.

Recalls are serious, but not all that common.  Sometimes there are less significant issues….when these occur a Technical Service Bulletin , or TSB, is issued.  This tells Denver auto service centers how to repair a frequent or difficult problem.

The automotive pros at Express Car Care in Denver get updated information through subscription plans, which can also be available in consumer versions for a reasonable cost.

So if you find yourself with a vehicle recall, get the work done at Express Car Care and keep you and yours safe.

 

 

New Fuel Filter?

by

Hello Denver drivers.  Today’s Express Car Care auto care post is focusing on your fuel filter.  Is it time for a new fuel filter?

When the fuel your engine is getting isn’t clean, your fuel injectors can start to become clogged and the engine on your vehicle may not get the proper amount of fuel at the correct pressure to run efficiently.  This hurts your fuel economy as well as your vehicle’s performance and can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

This is the reason why all vehicles sold in Colorado come equipped with a fuel filter.  The job of the filter is to clean out the small pieces of dirt and contamination.  Of course, the filter will eventually get clogged up and need to be replaced.  Fuel filters for diesel cars need to be replaced more frequently than those that run on regular gasoline.

If your fuel filter is clogged, the engine can’t get all the fuel it needs, and it may sputter at high speeds or quick acceleration.  These could be signs you might  need a new fuel filter.  You may also find that you need to get a new fuel filter more frequently as your vehicle ages.  Over the years, additional sediment and rust accumulates in your fuel tank and can be drawn into the fuel system.  Your fuel filter is the part that stands guard at the gates to your engine, to protect parts and to maintain performance and fuel economy.  If you would like more information on this subject, call us at Express Car Care at 303-691-2760.

Question on Your Transmission

by

Express Car Care Tech Question:
My name is Suzanne.  We were taking a camping trip at our favorite state park over a three day weekend.  About halfway to our campsite, the transmission went out on our vehicle.  It took all weekend to get it towed out and to get back home.  What can I do to prevent transmission problems in the future?

Express Car Care Answer:  Transmission repairs can be expensive at auto service centers.  On top of that, Suzanne was in the back country, her vacation weekend turned into three days of car repairs.

First of all, vehicle transmissions are tough and durable.  All that needs to be done to maintain them is to replace the transmission fluid on schedule.  The fluid gets contaminated with bits of clutch plates and metal.  Dirty transmission fluid under pressure acts like liquid sandpaper, eating away at important gaskets and seals.  Then your transmission doesn’t shift as well.  It can start to leak and overheat, and then you could end up in a situation like Suzanne.

Another thing to consider:  if you carry heavy loads, or are towing a trailer on the highway or up mountain passes, your transmission is working much harder and running hotter than under normal conditions.  Your transmission fluid may need to be changed sooner.  Check your vehicle’s owner’s manual for your severe service schedule or talk with your helpful and knowledgeable pros about when you should have your transmission serviced.  If you’re planning a trip that you know you will be doing some towing or other severe driving, make sure to have your transmission fluid checked before you head out.  It’s always better to be safe, rather than sorry.
