VIDEO: Hot Or Cold Spark Plug Torque

We discuss how and when spark plugs should be installed. This video is sponsored by Autolite.

A technician should never install a spark plug when the engine is hot.

When the engine is hot it can change the relationship between the threads on the spark plug and the cylinder head. This can change the torque readings from the torque wrench. In this video, Andrew Markel covers when and how spark plugs should be installed. This video is sponsored by Autolite.
