Air Conditioning Maintenance at Gilmore's Auto Service in Walnut Creek

Warm weather or cold, Walnut Creek drivers still need to think about their vehicle's air conditioning. Most Walnut Creek people don't service their air conditioning until after it fails. At Gilmore's Auto Service, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at Gilmore's Auto Service in Walnut Creek.

The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Walnut Creek vehicle owners know that air conditioning repairs can be costly. At Gilmore's Auto Service, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Walnut Creek drivers need to be aware that there's one more thing that isn't directly related to air conditioning service but does impact the quality of the air in your vehicle. And that's your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that come from the heater and air conditioner. The cabin air filter needs to be replaced when it's dirty. If you don't, it'll start to smell. Not all vehicles have one, so ask your Gilmore's Auto Service service advisor to check your cabin air filter at the same time they're doing your air conditioning service.

Strutting Your Stuff (Shocks and Struts)

Ever wonder how your vehicle is able to move over bumps, potholes and other irregularities in the road and you hardly feel a vibration in the cabin? It’s your shocks and struts doing the hard work along with the rest of your suspension and tires.  They keep the ride smooth and are important for your vehicle’s safe operation. 

So, how do you know when your shocks and struts are wearing out? One way is to look at the surface of your tire (where the rubber meets the road—where the tread is).  You might see some little indentations in certain spots, known as tire cupping.  If your vehicle takes longer to stop than it used to, takes a dive when you hit the brake pedal or bottoms out (scrapes) on a big bump in the road, that’s another sign, as are loud, odd noises.

You may also notice your vehicle sways more than it used to. Every once in a while, look around at your shocks to see what shape things are in.  If you see the rubber cover cracked or worn out or see a fluid outside your shocks, those are signs to bring your vehicle in to us so we can see what’s going on. 

Since shocks and struts contribute to the safe operation of your vehicle, this service is important. Shocks and struts are what help your tires stay in close contact with the road and help stabilize your vehicle. They also help electronic safety systems work properly, including anti-lock braking, stability control, and collision avoidance.  Bad shocks and struts are just going to get worse with time.

It's best to have regular maintenance done before anything goes wrong with your struts and shocks.  Your vehicle’s manufacturer has guidelines for how long those intervals are.  If you do start to see some of the warning signs, head on over so we can evaluate any problems.  We’ll replace the parts your vehicle needs and have you strutting your stuff once again.

Don't Blow a Gasket! (Valve Cover Gasket Replacement)

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs.

While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak.

You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out.

In some vehicles, taking off the valve cover and replacing the gasket is a relatively easy job. In some models, though, other engine parts are located near that part of the engine and must be removed to get at the gasket, so repair costs can vary widely.

The technician will measure to make sure the valve cover isn't warped so it can be reused. If it is warped, they'll recommend replacing it with the gasket.  

While the technician has that area of your engine accessible, they will also check to see if other components need replacing at the same time, which could save you money.  And because valve cover gaskets usually fail in older vehicles, the technician will check for other oil leaks then, too. 

One of the best ways to be sure your valve cover is doing its job is to have your vehicle regularly maintained.  The technician will periodically look over your engine compartment and make sure you know when things are showing signs of age and wear BEFORE they fail and leave you stranded.

That Squeal is Telling You Something (What Causes Squealing While Steering)

If you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong.  After all, it never made that noise before, right?  The sound  you hear may becoming from a few sources.  Let's take a look (or a listen) to some of the possibilities.

First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically.  For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. 

Sometimes that fluid gets low because of a leak or some other problem.  The belt could wear out and start squeaking, and you might feel the steering start to become harder.  Your service repair facility can figure out the problem and offer some solutions.

Another cause could be in your suspension.  Some components may not be getting lubricated like they should.  Or you may be hearing your tires squealing when you are turning. 

Properly working steering is a huge safety factor for your vehicle's operation.  Your steering affects handling, vital to your well-being as well as that of drivers around you.  So take your vehicle over to your repair facility and have it checked out.  You'll be doing everyone on the road—including yourself—a big favor by listening to your vehicle. When it comes to steering, silence really is golden.  Get that squealing repaired and get back to safe driving.
