How do you change the spark plug wires on a chevy 1990 lumina 31 engine?
I have a 1990 Lumina Euro, 3.1 and there are 2 ways to change the plugs and wires. The first is what some mechanics do, by rotating the engine forward and blocking it that way while they change the plugs, which is the way they changed mine the other day. The other way, is the way I change them, which is to remove the alternator and then you can get to the back plugs fairly easily without having to go through the hassle of rotating the engine forward. I prefer this way myself and I usually chane my own plugs, but I had to have some other work done on mine so I let them change the plugs and wires since I need it worked on while I was working. The front plugs and wires are easy to get to. Use sparkplug pliers to get the wires off the plugs. Hope this helps.
