Automotive Tips from KPS Princeton Garage: Air Conditioning ? Common Problem

Your auto air conditioning system cools and conditions the air in your passenger compartment when you are driving around Princeton. It also removes moisture from the air to keep your windows from fogging up.

A common A/C problem for Princeton drivers that visit KPS Princeton Garage is contaminated refrigerant (the gas that cools the air). The inside of the A/C hoses deteriorates over time and tiny fragments of rubber clog passages. This makes the system less efficient and overworks various components.

Leaks can develop at seals and gaskets and may reduce the amount of refrigerant, causing the system to work too hard to compensate. Dirty components can have the same consequences.

Ask your KPS Princeton Garage service advisor for an air conditioning system inspection to make sure everything is up to spec.

Move it or Lose It (Dormant Vehicles)

When it comes to your vehicle, driving it too much can cause some issues.  But what about not driving a vehicle enough? That has consequences as well.

Here are a few things that can happen if a vehicle isn't driven enough.  When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it.  And oil that sits around breaks down over time.  In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. 

You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles.  But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit from driving your vehicle at its optimal operating temperature for a while.

Spark plugs can deteriorate unless they are fired up.  The gas tank can rust from the inside if the metal is exposed from not having fuel in it.  Rodents and insects may see a sitting vehicle as a luxury hotel.  Brakes can rust after sitting around without being used.  Seals and gaskets can dry out.

One wise thing to do is check the operating manual. Some will spell out a maintenance schedule for vehicles that aren't driven regularly. 

One suggestion? Discuss your vehicle's maintenance with your service advisor. Let him or her know how often you drive the vehicle and what you use it for.  Then, you can come up with a maintenance schedule tailored for you, one that might not be covered in the owner's manual. 

If you do have a vehicle that's been sitting around for a long time, it may be wise to have it towed to your service facility rather than trying to drive it with brakes that may not work, spark plugs that may not fire reliably and other systems that may compromise your safety and those of others on the road. 

You may think it's great to have a low-mileage vehicle that you've barely driven, but a complicated, sophisticated machine such as a car, SUV or truck needs regular attention to keep it running safely… and reliably.

Don't Do It Yourself (Perils of DIY Vehicle Repair)

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, air bags and fuel injection just a small sample of the new technologies. 

Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of  much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s.

Today's most highly-trained technicians are able to keep up with how to perform the latest repairs and service by continuing education about their craft.  When once an auto repairman could do fine with a lift and a good set of tools, now specialized electronic analysis equipment and tools are must-haves when it comes to vehicle repair.

Because of how fast technology changes, access to the latest repair databases and manuals is also important.  Manufacturers require certain service procedures to be performed precisely, and any other way can leave a vehicle compromised when it comes to performance and safety. 

Your vehicle is capable of traveling at high speeds on challenging surfaces with ever-increasing traffic issues and unpredictable obstacles.  You need your vehicle to be working up to its engineered potential.  That's why you should leave repairs and service to professionals.  They work on vehicles every day, and years of experience with hundreds of repairs equip them to deal with the unexpected as well as the routine. 

When you develop a trusting relationship with a reputable service facility, you can have confidence that the maintenance, service and repairs are being done by people who know what they're doing.  Your safety and your vehicle's performance and reliability are well worth it.

Steer Me Right! (Failing Power Steering Hose)

Most drivers love how easy it is to turn their vehicles, and they have power steering to thank.  Engineers have figured out a way to take some of your engine's power to help you turn. Without it, steering can be quite a chore.  New power systems are electric, but there are still plenty of the older hydraulic power steering systems out there, and it's wise to keep them working the way they should so you don't find yourself stranded without power steering.

Those hydraulic power systems use a fluid under pressure that is pumped to a device that helps you turn your wheels more easily.  It's that pressure that presents the challenge.  After your vehicle's seen a few years on the road, you may find your steering isn't quite as easy as it was.  You may hear a groaning or humming sound when you turn. 

One component that can fail is the pressure hose that carries that fluid from the power steering pump to that turning assist mechanism.  The hose is made of rubber and can leak, crack, get damaged by heat and debris or just get too old.  If yours is ten years old or older, it's likely getting close to the end of its life.

If you think you can just wait until it fails completely, think of these possible consequences.  If the hose or a coupling fails, power steering fluid can blow all over the hot engine.  That fluid is flammable and can start a fire.  Or if you've been driving for a few weeks with low power steering fluid, that could ruin your power steering pump. Replacing the pump is an extra expense you can probably  live without.

A technician will replace the necessary parts and make sure air and contaminants are bled or flushed from the system.  Then, he or she will check for leaks.  Just think how important a properly working power steering system is for safe operation of your vehicle.  Make sure you keep yours in top shape for your safety's sake and the safety of others on the road around you.

A Head Start on Starting (Battery Testing)

If your vehicle isn't starting or doesn't sound like it used to when you crank it, the culprit may be the battery.  You may have left a light on, or something plugged into one of charging ports.  Maybe you accidentally left your vehicle in the "on" or "accessory" position when you last got out. Maybe you've left it in the garage or driveway for a long time without starting it.  That can spell the end for a vehicle battery.

It's also possible that your battery is just simply too old. There's no standard lifespan of a battery, but 3-5 years is about average, even though some people only get 2 and heavier duty batteries may last many more. It's possible your battery is defective, too.  And it could be your vehicle's charging system isn't recharging the battery. 

Whatever the cause, if you're having problems with your battery, it's a good idea to bring it in and have us perform a thorough battery test.  With state-of-the-art testing equipment, a technician will see if there's a bad cell in the battery or if it can be recharged.  We will also look at the date it was made. 

At the same time, the technician will look at the whole charging system, including the alternator, starter, cables, and connections.  From there, the service advisor can go through your options. 

Your best chance of not getting stranded by a dead battery is to have your system checked as part of a regular maintenance plan.  That should give you a head start on dependable starts.
