1996 Chevy Blazer plug changing

When I do them anyways.

I first gap them and put a little anti-seize on the threads. This isn't for everyone.I just it it that way.

Pull one wire off carefully as you don't want to damage the wire. Grab it and turn it colocwise and counter clockwise to release the boot from the plug and pull the wire off. Remove the old plug. Turn the new plug in by hand. You can do this 3 ways safely. Use a peice of vacum line on the plug and turn it, turn it by hand if accessible or use the socket and extention to start it. Don't damage the threads. IF there is a washer install it before starting the plug. Snugly tighten the plug. There are specs for tightening if you aren't sure how tight. Spray some di-electric grease in the plug wire boot. And reattach the plug wire
