GM parts on a Jeep
 
Had my Jeep for a few months. Had it tuned up, but had to get GM hoses to replace the old GM parts that were there so it would match up. Having some minor issues now, ordered a coil, but it had to be a GM coil to match up with the GM distributor. The guy even told me today that there weren't any Jeep parts on it, mostly GM. How can a Jeep (Chrysler) support parts from another make (GM)? Has anyone else run into anything like this?

stock radiator cap is a GM part as well.

HotRod90YJ 05-19-2011 05:19 PM

So this kind of thing is normal? I wasn't sure if this was common, or if the PO made a bunch of these changes, which could be the reason for the problems I've been having with my jeep.

last time I checked the YJ was an AMC product. the Mopar influence didn't hit until 92 and even then still mostly an AMC product. and being an AMC product they sourced a lot of GM

HotRod90YJ 05-19-2011 06:59 PM

Well, mine's a '90, so it would fall before the '92 Mopar influence. Thanks for the replies. The way the mechanic talked, this was out of the ordinary and not the way it was supposed to be.

Tony 76 05-20-2011 07:34 PM

Switch mechanic lol. Just kidding.

AMC means Any Motor Company. They used parts from anyone they could get their hands on. Some even used Motorcraft ignition parts. AMC was to poor to engineer their own parts. It was easier to rob from others.

Lol

This is very true. Not unusual to find GM or Ford parts in the AMC years.

This is common knowledge among a lot of YJ enthusiasts.Dont change mechanics but just do some Jeep homework and just learn for yourself when changes were made at Jeep corp.If you are a Jeeper for life then it can be a very valuable education,and being my own mechanic for 24 years I have found that Willy's/ Jeep CJ's ,YJ,TJ Wranglers etc... are some of the easiest vehicles you could work on .

Tony 76 05-20-2011 08:41 PM

S man I was just kidding when I said change mechanics.

superduty_5.9 05-20-2011 11:00 PM

Yes if it is a 2.5 4 cyl then it is a GM engine. Same one in the S-10's. Later 2.5's were different.

Yes, I'm a new Jeeper, so I'm learning all about the ins and outs of my YJ.

like someone said before the 2.5 aka is the iron duke by gm.. if u know of a cherokee from 84-86 and it has a 2.8 in it. thats the gm 2.8.... if u have a 4.2 then it should have the ford ignition... steering columns are pretty much out of like the old chevy trucks.. back in the day i believe they used a buick 3.8 in some of the cjs... and believe it or not the ax15 trans is the same as the toyota r150f except the input and output shaft are different. and the aw4 i believe is also a yota trans. just different parts so it bolts in the jeep... there is some examples that i can think of right now.

deathphoenix99 05-23-2011 06:40 AM

^Yea, the steering columns in the older jeeps is the Chevy truck column, I've grabbed parts from one in the junk yard once for my truck.

JODY HOWLAND 05-23-2011 09:28 AM

I have a 90 model also and I recently upgraded to hei ignition and it is a gm part

You are correct that AMC did source parts from other makers. Taken another way, it helps to keep costs down (and profit up) to use a distributor from GM or a Borg-Warner or Chrysler automatic transmission (both examples on late 60s /70s AMC) or later a Ford sourced ignition on the original YJs. Why engineer another part when you don't have to? Ask yourself why does Motorola supply alternators to many makers?

If AMC made a mistake, it was the 70s Matador coupe that sent the company down the tubes. Nice enough car (and I like Teague styled cars!), but it just didn't sell enough to justify the cost of producing it.

Another thing that really hurt AMC was the UAW. Yeah, that's not a PC subject to bring up in today as the U.S. races for equitable re-distribution of everything, but the UAW really bent AMC over. Those costs drove AMC into the arms of Renault and the rest is history.

With rare exception, AMC engines are AMC produced (Iron Duke 4-banger from GM for an exception). The 390 V8 was not a Ford engine, etc. The bodies were all AMC and they had many innovations (first all plastic interior is a weird example, but all cars are that way now).

Chrysler bought AMC in 1987 for one reason -Jeep. At least give AMC props for keeping Jeep alive after mismanagement by Kaiser.

I remember reading about the 2.8 chevy motors in cherokees,do you know if they used a borg warner tranny or did they use an AMC product ? Googling but not really finding anything on that .

Thanks man answered my question ,anyone know if anyone on here has transplanted a GM 2.8 into a YJ ? Just curious,because I have access to one.

deathphoenix99 05-26-2011 06:20 AM

I'm not saying don't put a 2.8 into your Jeep, but a lot of guys with the s10 that have 2.8's swap it out for the 3.4, which uses the same wiring harness and computer, just a bigger engine with more power. There's a few things they have to swap over...but if you already have access to a 2.8, it'd be better than a 4-banger.

shin 05-26-2011 09:24 AM

or why not go with a 3.8 supercharged out of a gtp...

Would a hemi work in a JK? Saw a charakee with one on YouTube and it sounded awesome!

Yeah I have owned s-10's with both the 2.8 and 4.3 ,the 2.8 was way better on gas and definitely has more power than my 2.5 .The 4.3 is basically a small block with 2 cylinders removed .Believe me I love HP as much as the next guy but she is my DD and I gotta try and keep the gas mileage in check .Just thinking it could be a good swap for me to do .

That would be sweet but I have a 2.8 at my disposal and all it may cost me is a 12 pack of beer .

I hear what you're saying. But one thing I have noticed with most newer vehicles, is that on the highway, the bigger engines do about just as good on gas mileage since they can run at lower RPM's and consume less fuel making them more efficient. In the city, especially in winter climates, yea the smaller engine will excel in gas mileage. but on the highways, it's not too much different.
I love the 4.3, that'd be a good swap in a Jeep too, and I know it's been done. The 4.3 is designed off of the small block 350, it uses the same bore even. I know quite a bit about s10's.
