how do i remove spark plugs from an 1987 firebird?

[Ryan W]

i thought it was with a 5/8 spark plug socket but that just doesn't go on. i don't know it that's the wrong size or if something is preventing the socket from going on. The 5/8 fits the spark plug replacement but doesn't go on the old ones, what's up with that?

should be 5/8, but i have run into the same problem, it turns out that NGK and Bosch platinum+4 plugs needed to use a metric socket, i think it was a 14 or 15 MM 12 point socket

you probably need to buy an older model plug wrench. And then double check to make sure you bought the right replacement plugs. And while you are there do yourself a favor and buy a tube of plug boot grease and use it liberally. it will be a lifesaver next time you go to change plugs.

double check too see if you got the right plugs....it may be a 13/16 socket..

First off if you can ,use a compressor and an air blow gun with a good reach tube and tip ,to blow out any dirt or grease or loose rust from around each and every plug and recess (especially if steel insulator tubes are protecting plugs ) This reduces the chance of debris in the threads and falling into the cylinder when plug is removed on any head .
You probably need a metric socket [15mm 6 point deep well] (this works well even on a rusty 5/8 Th's plug, and you can put the rubber cushion that protects the Porcelain of the plug from a 5/8 plug socket into it),definitely some dielectric grease to keep the boots and tip from getting stuck on the plugs .And be sure to thread the plug into the opening before ratcheting it in (to prevent a cross threading /stripping of threads from plug or head .
