Generally speaking, a 50/50 mix of water and “antifreeze” is the recommended norm. However, when mixing concentrated antifreeze with water, avoid using tap water, as this may contain excess calcium or other materials which can promote corrosion. Use only distilled/deionized water for the mix. Granted, some coolants are available as 50/50 pre-mix that eliminates the need to add water.
There is no worse feeling for a tech than to have performed a straightforward, uncomplicated brake job and see the vehicle return with a concern or a complaint. The customer can raise his concerns immediately after the repair or in the weeks or months following.
On a business trip several years ago, I was in a country that has no emissions regulations. The hotel parking lot was filled with late-model rental cars, but cars parked on the street were much older and obviously well past their best years. The strong smell of gasoline on those sun-baked streets made it obvious that a functioning evaporative emission control system (EVAP) was not important there.
I hope I’m not alone in this. One of my pet peeves is the all-too-common misuse of the term “turbocharged.” It seems as though manufacturers of just about any product feel that they can freely apply the term to promote the benefits of a host of consumer offerings.
Rather than covering programming and relearn procedures, a subject that has been addressed in select previous issues, this article focuses on common (and uncommon) concerns that a technician may encounter, along with tips to avoid mistakes.

The typical wheel bearing grumbles are about strange noises, rumbling feelings or an anti-lock brake (ABS), electronic stability control (ESC) or traction control system (TCS) system light or issue.
Most of the normal service and repair required by a hybrid vehicle is the same as other cars. They all need fluid changes and brake service, they all have oxygen sensors and EVAP systems and they use the same generic OBD-II fault codes as their non-hybrid cousins.
Ah, the lowly fender cover. It was born with a single life mission: to protect the painted surface of a front fender from nicks and scratches while underhood work is being performed.
Let’s take a look at various suspension parts inspections, including ball joints, wheel bearings, wheel hub units, control arm bushings and more.
General Motors’ EcoTec3 family of engines is a familiar sight under the hoods of many GMC and Chevrolet pickup trucks and SUVs. It is available in three versions: 4.3 V6, 5.3 V8 and a 6.2 V8. General Motors debuted this new engine design on the 2014 model year trucks and although the 6.2 V8 versions look comparable to the GEN 5 V8 LT of the Corvette and Camaro, they are uniquely individual engines.
