pontiac735 Posted December 17, 2005 Report Share Posted December 17, 2005 Hey there....I have a crack in one of my coils,which I can see arcing when it's dark.I was gonna change it but as usual,the little bolts that hold the coil pack is corroded :x ....so I guess I'll have to take the whole thing out,which I've never had out before.So is it only 2 bolts that hold it on?And 2 harness clips?Hard to see down there without getting under it.90 STE is the car.Thanks in advance.

Regal_GS_1989 Posted December 17, 2005 Report Share Posted December 17, 2005 The ICM, which is the base that all of the coil packs are attached to, acutally has 3 bolts holding it on to the motor. there are 2 on the sides, and one on the bottom, a little to the left of the center. I know on mine, there was a coolant hose in the way, but once i put it back in, i only put in the 2 bolts on the sides, so it will be a lot easier for me to remove next time. and yes, there is only 2 wire harnesses. One on the left, and one on the right Quote Link to comment Share on other sites More sharing options...
Crazy K Posted December 17, 2005 Report Share Posted December 17, 2005 the bolts use a funky 5.5 mm socket. If you can get one, try that before you bother taking all three bolts out. Additionally, it you pull both bolts from all three coils, they are the only thing holding the module in as well, so it's faster to do it remove it that way than to fight the three bolts.

pontiac735 Posted December 18, 2005 Author Report Share Posted December 18, 2005 Thanks for the replies...I wound up having to take the whole assembly out....those bolts on the coils were in hard shape,so I had to take it all out.It's finally back to normal.

joey b Posted December 19, 2005 Report Share Posted December 19, 2005 2 harnesses? There is one that feeds 12V with ignition, one with a signal from the crank sensor and one from the ECM. --3-- Quote Link to comment Share on other sites More sharing options...
