Tech Tip: Maintaining Belt Tension is Critical
Most late-model engines have serpentine belt drives for the engine-driven accessories. And most people know that belts are a maintenance item and eventually have to be replaced. But many don’t know the spring-loaded automatic tensioner that keeps a serpentine belt tight is also a wear item. Consequently, the automatic tensioner may also have to be replaced when the time comes to change the belt.
Diagnostic Solutions: Fuel System Pressure & Volume Checks
For maximum efficiency, modern import fuel injection systems require that fuel be delivered at a specified volume and pressure. Because the fuel injector’s job is to mix fuel with the intake air charge, it must produce a finely misted, conical spray pattern through the fuel injector nozzle. Lower-than-specified fuel pressures not only fail to provide
Computers: Why You Can’t Do Business Today Without Them
It’s hard to imagine any automotive repair shop doing business today without the benefit of multiple computers.

Tech Tip: Diagnosing a Worn Wheel Hub Bearing
Signs of a worn wheel hub bearing vary in severity. Some may be difficult to detect, leading to damage before corrective action can be taken. The time frame in which damage occurs is linked to driving conditions and/or the mechanical practices that were followed at installation. Noise is a classic sign of a bad wheel bearing or wheel hub bearing.
Chevy AVEO Timing Belt Service
As a rule, General Motors uses timing chains rather than timing belts on most of its engines. Timing chains are long-lived and reliable, and do not have a recommended replacement interval. Not so with timing belts. One GM engine that does use a rubber timing belt is the 1.6L E-TECH II engine in the 2004
