FAQ for Spark Plug Repair
Q: What's the installation procedure for the spark plug?
A:
The installation procedure is to measure the spark plug gap on the spark plugs to be installed, compare the measurement to the gap specifications, install the spark plugs to the engine, and connect the spark plug wires to the spark plugs.

GM Specialist
01/11/2022Q: How do you inspect for a broken, worn, or loose center electrode?
A:
You can inspect for a broken, worn, or loose center electrode by shaking the spark plug, and a rattling sound indicates internal damage while a loose center electrode reduces the spark intensity.
By Bob
GM Specialist
01/11/2022Q: What should be done before using the spark plug?
A:
You will need to ensure that the correct spark plug is installed. An incorrect spark plug causes driveability conditions. And you need to ensure that the spark plug has the correct heat range. An incorrect heat range causes the conditions such as spark plug fouling-colder plug and pre-ignition causing spark plug and/or engine damage-hotter plug.
