Air Conditioning Maintenance At Pella Car Care

Tuesday, February 28th, 2012

Warm weather or cold, Pella drivers still need to think about their SUV’s air conditioning. Most people don’t service their air conditioning until after it fails. At Pella Car Care, we can advise you on your vehicle manufacturer’s preventive maintenance for air conditioning service, just as we do for transmission service, oil changes and so on.

air conditioningMaintaining 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 Pella Car Care.

The refrigerant also contains a special 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 car owners know that air conditioning repairs can be costly. At Pella Car Care, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Corrosion is what leads to many air conditioning system failures for Pella motorists. The small leaks mentioned earlier also mean that air and water can leak into the air conditioning system. This can lead to rust and dirt in the internal workings of the air conditioning components. This greatly accelerates wear and, ultimately, failure.

Air conditioning service at Pella Car Care starts with a visual inspection of the components for signs of damage or leaks. The compressor is driven by a belt from the engine, most often the serpentine belt, so it’s inspected for cracks or wear. The air conditioning compressor and other components are checked for proper operation. Then comes the leak test. If a leak is detected, often in a hose or connection, it’s repaired and the system is retested.

Then the old refrigerant is evacuated and the system is recharged with clean, fresh refrigerant. A final test insures that the vehicle’s air conditioner is working, and you’re on your way.

How often this should be done varies from vehicle to vehicle. Your owner’s manual will have the manufacturer’s recommendation and, of course, your Pella Car Care service advisor can tell you.

If you’re not getting enough cool air you know something’s wrong. Also, if you hear strange sounds when you turn the air on, there might be a problem with the compressor and you should get it checked out at Pella Car Care. Replacing a bad A/C clutch is cheaper than waiting for it to ruin the compressor.

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 comes 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 Pella Car Care service advisor to check your cabin air filter at the same time they’re doing your air conditioning service.

Serpentine Belt Service At Pella Car Care

If you’ve ever heard a squealing sound under your hood, chances are it was your serpentine belt. Your serpentine belt is a long belt that’s driven by your engine. It winds around several accessories that power important automotive systems in your SUV. Let’s go over them.

First, the serpentine belt drives your air conditioning system. It spins the compressor that makes the cool air that takes the edge off the summer heat in Pella.

. The alternator creates electricity that’s used by your SUV’s electrical systems and also charges your car battery. Without the alternator, the battery will go dead in a few miles.

The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).

And, on most vehicle’s, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. On some cars, the water pump is powered by the timing belt instead of the serpentine belt.

When they understand what it does, Pella drivers realize that if it breaks, it affects a lot of systems. That’s why manufacturers have recommended that it be changed every so often so that it doesn’t fail.

At Pella Car Care, we can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon. If the belt has more than three or four cracks every inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.

If it has lost a significant thickness, it also needs to be replaced. There’s a special spring-loaded pulley attached to the engine called the tensioner pulley. Its job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip. The spring can become worn and no longer provide the necessary pressure to keep the belt tight. At Pella Car Care, we often recommend that the tensioner be replaced at the same time as the serpentine belt.

As mentioned, a squealing sound could be a sign that the serpentine belt needs to be replaced. It may be loose if you hear a slow, slapping sound when idling.

All in all, the serpentine belt’s an important part for the function of your vehicle. And it’s not that expensive to replace at Pella Car Care – so it’s good to do so before it fails.
