R&R Coil
First remove the ignition coil module and heat sink located right above the coil. Then use a small sharp chisel and hammer to cut off the rivet heads holding your old coil on, cut them off flush with the bracket face, then use a drift punch to knock the rivets through the holes and out the bottom.
IMPORTANT: when you re-install the iginition coil module and heat sink, don't wipe off the white silicon grease between the mounting faces. The silicon grease is for heat transfer and is very important for proper cooling of the ignition coil module. I picked up a new small tube of this grease at Radio Shack and re-coated the assembly prior to re-insatlling it.
Hope this helps, captbob33

coil module
couldn't get rivets out with module still attached but got it out of the car and got every thing replaced. going back in the stud that holds the power steering resivoir only went in 1.5 turns and tried to strip and i stopped there. only way i can see to complete repair is to remove everything on the passenger side between the head and radiator to get enough room to move around. i thought that buying a factory manual would help in these repairs but it looks like that the author didn't talk to the engineers that designed the car.

Gotta ask - where do you live?
I've got a ton of car projects for this weekend so I'll be working on them all weekend. I've done this exact same job on my 92 soo many times I can do it with my eyes closed.
If you are close by you could come over and I can show you the "easy" way to change it. Its really tough to describe.

tooooooo far, I'm outside Atlanta.
OK couple of tricks, if you follow the powersteering resevior mount near the bottom of the engine you'll find the second bolt for it. IIRC I take it all the way out then remove the nut on the upper part of the mount. Now you can move the resevoir out of the way enough to use a deep socket to remove the stud holding the heatsink/icm/coil assembly. I use a socket and a logn extension on the bolt on the other side.
When mounting a replacement coil I used a dremel to shorten the mounting screws. I had to play with orientation to get them in so they wouldn't interfere.
The last time when I just needed to replace the ICM I was able to get a real small socket on both of the small bolts holding it on.
When replacing the ICM - BE SURE TO USE HEAT SINK COMPOUND between the ICM and heat sink.
