Here are some tips to follow when replacing a spark plug.
Every time a spark plug fires, the spark burns a few molecules of metal off the plug’s electrodes. Over time, this eats away the electrodes and rounds off their sharp edges. The erosion gradually increases the gap between the electrodes, which, in turn, increases the firing voltage required to generate a spark. Eventually, the point is reached where the ignition system fails to produce enough voltage and the plug misfires.
OBDII connectors serve as the main communication point between the technician and the vehicle.
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.
ABS is the foundation of the ESC system. ESC systems add software and multiple sensors to keep the vehicle under control.
New cooling systems anticipate and influence changes in coolant temperature.
Look at the condition of the additive package and the freezing point to justify coolant replacement.
