Serpentine Belts: Inspecting And Replacing
A technician’s senses are often the most valuable tools in helping assess what repair or replacement parts are needed on a given job. Specifically, the ability to visually inspect parts for wear and tear to know when it’s time for replacement is the calling card of any successful technician.

Vacuum Power Assist Service
Most late-model vehicles use a vacuum booster to help apply the brakes. The booster is usually located behind the master cylinder on the firewall. A leak in the vent valve can cause a reduction in the performance of the booster and increase pedal travel. A manifold vacuum of 20 inHg or greater can be achieved during deceleration. The booster chambers can be evacuated and retained at this pressure by a properly operating check valve.

The Science Behind Precious Metal Spark Plugs
The higher melting point of iridium and platinum allows spark plug manufacturers to reduce the diameter of the center electrode. The smaller the diameter of the center electrode, the lower the voltage needed to start the spark. The finer point means that the electrode can absorb heat easier and faster, leading to improved acceleration, fuel consumption and smoother idling.
