Engine

Is there a secret to changing the spark plugs on a 2001 GMC 8.1 liter. The wires seem to come of very hard.

You have a plug wire then a metal shield. Does the wire pull straight off and then the shield come straight out? I don't want to do damage.

See this Spark Plug Wires
INSPECTION
REMOVAL & INSTALLATION
Label each spark plug wire and make a note of its routing.
Twist, then pull the spark plug wire from the spark plug and then from the coil pack.
