How to Change the Plugs in a 2000 Silveradoby Lee Sallings
The 2000 Chevy Silverado is equipped with a coil-over-plug ignition system that features individual coils mounted on the valve covers over each spark plug. This system allows the on-board computer to adjust the timing to optimize each individual cylinder. Replacing the spark plugs is a simple maintenance service that the home mechanic can easily complete in an afternoon. No special tools or skills are needed.
Remove the spark plug wire from the number one cylinder (front plug on the driver side) using the spark plug wire pliers and a twisting/pulling motion. Unscrew the spark plug from the cylinder head using the spark plug socket, a three-inch extension and the socket wrench. Repeat for the remaining three plugs on the driver side of the engine.
Coat the threads of a new spark plug with a light coating of anti-seize compound, and screw it into the spark plug hole by hand. Tighten it snugly with the spark plug socket and wrench. Reinstall the plug wire onto the spark plug by pushing until it snaps into place. Repeat for the remaining three plugs on the driver side.
Remove the air-filter housing located on the left (passenger side) of the engine compartment by releasing the latch and loosening the clamp that attaches the air duct to the throttle body. This allows access to the passenger side plugs. Remove and replace the spark plugs in the same manner as the driver side. Reinstall the plug wires, air filter housing and duct. Start the engine and test drive to verify the repair.
