Ignition Module Install
 

Finally got around to replacing the ignition module on the back of the distributor after my 1990 starting to act odd.

What do I use on the plate that mounts against the distributor? It had something on it from the factory, not sure if it was die-electric grease or what it was.

It runs much better, for a while... Specifically until it loosens and starts falling out because I lost BOTH screws. Im sure they are out of sight on the back of the motor somewhere! Gotta get new screws today, anybody know exactly what kind of screws I need, cause I never even got a look at them.

NOTE: Use a magnetized tool to get those screws out. Or pull the distributor like the manual says...

I think I have a distributor with a bad bushing that I could steal some screws from if you need them. I might not have the security torx, as I have never had a TFI go south on me yet (and I am not even use if they use secutiry torx on that dist). I will just have to see. Or take one with you and see what the hardware store has.

It needs thermal grease, to transfer heat - without it, you will be replacing it again soon.

I used di-electric grease, Im going to order a remote mount kit for it eventually. Ill pull it back off and use thermal grease instead until then.

I found the correct thread and got an allen head that was much longer than I needed (for easier handling) and used an aluminum spacer. Even if I didnt loose the screws, these were WAY easier to get in.

Hey, what ever holds it on there !! :)

The screws are hex head screws and they sell a short nut driver especially for this job. They are 7/32" hex retainer bolts as they are called on the AmPro Ford ignition Module Tool, I bought, and the AmPro part number is T71266. A 7/32" socket will work if you can get at it with a 1/4" drive ratchet.

I changesd several of these. On the last one, I added a piece of Aluminum flashing between the Ignition Module and the distributor to act like a heatsink. I let the "heatsink" extend out iinto the open at the bottom of the Ign Module. I coated both sides of the "heatsink" with "Artic Silver" computer processor heatsink paste. I got tired of messing with this "better idea of Ford" and putting up with the missing caused by heat. This was a big customer complaint and no doubt why Ford quit putting the ign module on the dist.
