Without more information about the type of engine, and the vehicle it is in, all you can expect to get is generic information. Generally, with the engine cold. You need to remove the spark plug wire from the plug, twisting while pulling on the "boot" not the wire! Next find the correct spark plug socket,(one that the new spark plug fits into, AND holds the spark plug. Now make sure the place that the old spark plug is screwed into is clean, using compressed air blow out around the old spark plug to keep dirt and sand from falling into the cylinders (scoring/scratching the life out of them!) Using a 3/8" drive rachet, an extention and the spark plug socket, put the socket in the hole that you removed the spark plug wire from and turn the socket counter clockwise until the spark plug is free. Inspect the spark plug for unusual wear, or deposits this could be a sign of engine problems. Take the new spark plug check the gap!! if it is correct place it in the socket and start theading it in the spark plug hole by hand, turning it clockwise. Tighten the plug firmly, but not till all the veins pop out of your face. Reinstall the sparkplug wire you should feel it snap onto the end of the spark plug. Continue on with each of the other spark plugs making sure to always put the exact same wire onto the plug you took it off of.

Note it is a good idea to put a small amount off anti-sieze compound on the threads of the new spark plugs to aid in the installation and removal. Also when reinstalling the spark plug wires use some silicone grease in the boot so that next time the boots will pull off easily.

I hope this is some help. Melvis

How do you change the spark plugs in a 1987 Chevy Celebrity?

To change the spark plugs in a Chevy Celebrity: 1. Give the spark plug boot a twist to free it up from the spark plug, then pull on the boot to remove the spark plug wire from the spark plug. 2. Use a 5/8" spark plug socket with an extension and ratchet or breaker bar to loosen then remove the spark plug. 3. Set the gap on the new plug to .045" then screw it back into the spark plug hole in the head. Tighten the spark plug and replace the spark plug wire.
