Uh Oh…My Check Engine Light Is On

March 30th, 2017

So you come out to start your car one morning and the Check Engine light on the dashboard comes on…and doesn’t go back off again. You can’t really notice any difference in the way the car runs and drives, but it’s on anyway.

What does it mean?Check Engine Light

Since the late 80s, most engine functions have been controlled by a central drivetrain computer. This includes emissions controls, fuel metering and delivery, ignition timing, shift points and many other elements of drivability and performance. The drivetrain computer relies on information from a chain of sensors that monitor exhaust composition, camshaft position, throttle position and many other factors.

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]

Questions You Shouldn’t Be Afraid to Ask Your Auto Repair Tech

March 17th, 2016

Often, drivers are mystified by how their cars actually work. It’s to be expected. Even an older car is a complex machine with many sub-assemblies that all work together to move it down the road.Car questions? Ask them!

As a result, drivers tend to be a little intimidated by auto repair and often tend to not inform themselves by asking the necessary questions of a tech or a garage. Too often, that ends up being a big mistake. Here are some examples of the kinds of things you really should know before any auto repair work starts:

  • Does your shop work on any kind of vehicle? Of course, most shops can service a product from GM, Ford, Chrysler, Nissan, Toyota and the other leading makes. Some makes, however, require a lot more training and experience, o ...[more]
