How To Maintain A New Car

May 25th, 2017

So you got a new set of wheels – congratulations! You’re going to want to hang onto it as long as possible, so you’ll want to keep it maintained as well as you Car Maintenancecan. Here are some suggestions:

First, read the owner’s manual carefully and stick to manufacturer’s recommendations for service intervals. There are certain things that are critical enough that failure to adhere to recommendations can void a new car warranty. Don’t let that happen!

For instance, just about every manufacturer recommends synthetic oil for their engines; it provides better protection in just about every respect, and it’s more stable at high and low temperatures. If your owner’s manual prescribes a 10,000-mile oil change, stick with that and be sure to use the bra ...[more]

Spark Plugs – How Often Should They Be Replaced?

April 27th, 2017

In the old days, a tune-up was necessary about every 35,000 miles. It would usually consist of setting the ignition timing, replacing the mechanical breaker points in the ignition, cleaning and adjusting the carburetor and replacing the plug wires and spark plugs. Today, of course, the carburetor’s job is done by fuel injection and the ignition timing and spark are controlled by the engine computer. Few vehicles still have plug wires anymore either, as the distributor was replaced by the computer and a coil-on-plug design which delivers a spark at each spark plug.

But what about the spark plugs themselves, though? How often do they need to be replaced now?

Manufacturers tout an 80k-100k mile service interval on spark plugs now, thanks in part to improvements in plug design and materials. That might be stretching it, however. Remember that if you have a 100,000-mile spark plug, its electrode is worn down 4/5 of the way at 80,000 miles. A worn ...[more]

Things To Look For When Buying a Used Car

September 15th, 2016
Buying a used car is somewhat less of a crapshoot than it was at one time. You can get detailed information on a vehicle's history via the CARFAX report, and a Car for saletechnician can use onboard diagnostics to get a good picture of what's going on under the hood and what problems might be coming up. 
 
It's always a good idea to get a mechanic to look over any prospective purchase, but there are things you can get a look at yourself before you spend the money for a professional inspection. These are things which will give you a pretty good idea of the kind of use and maintenance a vehicle has seen before you got it. 
 
-- Put your head against a fender and sight down the side of the vehicle with one eye. Look out for ripples or ...[more]

What's Leaking From My Car?

July 14th, 2016
You go out to your car, start it up, pull out of your parking space and see a puddle of...something...where you were parked a moment ago. This is never a good feeling. What could it be? 
 
Fortunately, some automotive fluids are dyed different colors to make this a little easier to narrow down. 
 
Does it appear to be water? Were you recently running your A/C? Chances are that's just condensation from the A/C system, which drips out through a rubber tube and is perfectly normal. No worries there. 
 
For years, antifreeze was dyed a bright green to make it easy to identify. Today, other antifreeze formulations can be colored pink or orange, but it's still not hard to figure out -- antifreeze has a swe ...[more]

A/C Problems Demystified

June 30th, 2016

Believe it or not, the A/C system in your vehicle is fairly simple in principle and design. Like your refrigerator, it operates on a cycle of compression and expansion of a gas, known as refrigerant. The compressor turns the gas into a liquid, and as the gas evaporates it provides cooling. Like your refrigerator, its main components are: 
 
  • Compressor
  • Condenser 
  • Receiver/dryer
  • Thermostatic expansion valve
  • Evaporator
  • Refrigerant
  • Blower 
The good news is most automotive A/C systems have become very robust and reliable compared to cars from a generation ago. Most of the time, poor performance is due to low refrigerant levels due to lea ...[more]

Regular, Synthetic or Blend...What Kind of Oil Do I Need?

May 26th, 2016

At one time, there were only a couple of choices for motor oil. Today, that is no longer the case, and hasn't been for quite some time. Here's a quick breakdown of what you need to consider when it's time for an oil change:

  • Viscosity: Viscosity is how thick your oil is, and how it retains its pour properties at various temperatures. In this respect, synthetic oil is far superior. Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. Check your owner's manual -- many newer models require a thinner, lower-viscosity oil, which also helps the engine run more efficiently. Viscosity is expressed as a numerical value -- the lower the number, the thinner the oil. Many are designed to work a ...[more]
