My kid bought his first car and bought an 01 Cherokee. Got it home and realized the coil pack is not bolted in at all. I’ve been trying to find out what size bolts do we need to get? Does anyone have the specs on these bolts?
So I did the Viper coil mod and decided to plug those four holes with bolts. M8X1.25X12 is what I used.
But the length is not correct cause I was just looking to fill the hole to keep crap from getting in there.
I figured I just looked up the bolt in my parts catalog. Not always but sometimes they give the specs.
Pretty sure this is the part number, 6102146AA, but no specs.
Could not find anything with a quick Google search either.
So while I can't remember for sure going to guess I just matched them up at the hardware store.
So here is a picture of one so you know what it looks like.
Now something else popped into my head.
Are you sure that is the original head on the Jeep?
Are there 4 holes in the head for the bolts to screw into?
Cause in '00's and '01's cause of the 0331 cracked head issue sometimes guys put a different head on the Jeep.
And not all heads have the bolt holes in them for the coil rail.
When guys do that they usually fab up some brackets for it.
This might explain why the coil rail is not bolted in on the Jeep.
So not in this instance but maybe in the future this might come in handy.
Might want to give it a quick read.
Thank you. Could you possible tell me the length of the one in the photo.
yes it’s the original head, it looks like the just forgot to put the bolts in, but I don’t have one to compare to. I searched for several hours on line for part numbers or specs.

I would have to find them.
I know have them. Cause I don't throw anything out, LOL, but where is a totally different story.
See what I can do and post the size if I can find them.
