Air Conditioning

How did we ever get along without air conditioning in our cars? It's a feature we take for granted until, suddenly, it's blowing hot air.

In the past few years, many owners have discovered that fixing an inoperative air conditioner can cost a few hundred dollars or more, depending upon the make and model of vehicle. The reason is that the old standby R-12 refrigerant, trade named DuPont Freon, has been replaced by R-134a. Touted as being environmentally safer than its predecessor, R-134a has been standard since 1994.

Thanks in part to advancements in health care, our 65 and over population, presently at 13% of the total, will be 20% by 2030 (source Washington Post). Technology has worked wonders in extending the life of our vehicles, too. Median car life has nearly doubled to more than 9 years. “As a result of technology the quarter million mile vehicle no long is a miracle,” says Rich White of the Car Care Council. Engines and drive trains are superbly refined, as are fuels and lubricants. Equipment developments and the personnel training to go along with them have added to this formula for long life.

A fairly common household disaster is flooding of the laundry area due to a split hose on a washing machine. Also vulnerable to a similar disaster is your car. A bulging radiator hose, carrying hot water (coolant) under pressure, can rupture.

It was among travelers’ worst nightmares and a very expensive trip for this motorist. His beloved pickup blew the engine and had to be towed 250 miles home. The temperature gauge didn’t work, nor did the check engine light. By the time he realized the engine was overheated the damage was done.

Changing the many fluids in a vehicle is always a change for the better. Dirty engine oil, transmission fluid or anti-freeze are bad news for a car. But what about brake fluid? Many motorists know that this fluid should be topped off, but changed?

The Car Care Council’s short Gas Saving 101 Quiz is a reminder to all motorists that the number of miles per gallon (mpg) a car gets is directly related to driving behavior and vehicle maintenance.  

“Motorists can very easily save money on gas by driving smarter, and keeping an eye on a few of the vehicle components that affect fuel economy,” said Rich White, executive director, Car Care Council.

Q. 1 – Properly inflated tires improve gas mileage?  

You’ve just made your last car payment. Should you keep the car or trade it in for a brand new vehicle? According to the Car Care Council, keeping your car rather than buying a new one is the way to go, especially if your goal is to save money.  

“People who keep their cars, treat them as valuable investments and commit to regular vehicle maintenance, end up saving a lot of money,” said Rich White, executive director, Car Care Council.  

Losing a belt today can mean big trouble for the engine because serpentine belts are used on most engines to turn the water pump, alternator, power steering and air-conditioning compressor. If a belt snaps, everything is lost and you may be stranded. Older cars use individual V-belts for these various accessories. A blown hose could result in an overheated engine and can cause additional engine damage.

“My customer asked me how much he’d have to spend for a pair of shocks,” said a repair shop owner. “I told him there are ‘good, better and best’ prices, but I install only the good and, preferably, the best. Labor is the same.”

His customer agreed that the minimal cost difference did not justify opting for less than the best. What price is peace of mind? It’s a factor that plays a big part when investing in auto repairs. Once a component is installed you’re likely never to see it unless it fails.

Worn out tires and windshield wiper blades are symptoms of neglected vehicle maintenance that put drivers and passengers at serious risk during the typically rainy months of spring.

Thin tire treads create hazardous driving conditions when water builds up on the roadway, according to the Car Care Council. Deep tread accommodates accumulated water; thin tread does not. Thin tread causes the tire to hydroplane – ride up on a film of water, losing contact with the pavement, similar to driving on ice.
