Oh I am absolutely happy with the time I took to source the parts and install it. Actually only took me a weekend to install everything. I had several factors to keep me with the 2.5L. An uncommon engine, everyone swaps to the 4.0L because it’s better, not a lot of knowledge out there and I decided a year into my build to keep my MJ stock so I only stuck to doing things right and the factory way. Overall, keep invested and that little engine will take you for a long time.

Yes, but the vehicle has to have the factory set up as there’s a dealer installed set up as well that looks like a bunch of small bracket pieces cobbled together to have the AC in the system. Unfortunately the catalog I have access to only shows the bracket I have only lets me see vehicles to 84 and it says the bracket was used from 83-90 in the XJ, CJ, YJ and MJ. As long as it’s factory installed, you’ll find the brackets.

Here’s what the AC bracket looks like. It’s missing the rear compressor support piece but I found them at a now defunct Jeep yard.

So it’s a two piece set up. The alt bracket and AC bracket go together. The diagrams I provided show all the pieces you will need for this set up. I had to spend a couple years hunting down my set up. I do actually have the AC portion of the bracket but I do not posses the alt pieces. Now this set up is shared by its cousin, the 4.2L AMC I6 which is kinda nice meaning the parts can be found. Unfortunately the 2.5L is such a hard engine to find accessory parts for because everyone hauled them off to the scrap yard in favor of the 4.0. So finding one fully loaded is a trick. The alt bracket you can possibly get fabricated but the AC bracket can not be.

That is because those are 4.0L HO(top) and 4.0L Renix(bottom) AC brackets. Here is the 2.5L: And what it looks like together:

Love seeing another 2.5L on the road.

Wonder who got it.

Yeah. I just want to make sure everything is right for this guy. What’s funny but I omitted before is he has the heater core completely eliminated for whatever reason so the hose from the water pump goes right to the intake manifold. Basically bypassing the non existent heater control valve which is fine. AC system is factory to this truck and has been disconnected for a bit. I recommended to the owner to get a new condenser due being open and exposed. I really do want to put the heater back into the system but some hoses are lacking at the moment to put that back in. But swapping the radiator is planned. I did examine the engine and didn’t see anything plugged up anywhere so we’re good there. Could be remnants of gunk in the system somewhere that was missed in the flushing. Supposedly the owners neighbor works on radiators and recommended to get a new radiator. Not sure if it was tested but I’m assuming this was based on a quick examination by the radiator guy.

NEW LISTINGColorado AMC Jeep Denver, Colorado CO Dealership Emblem (ebay.com) For you Colorado folks.

Reservoir was clogged. Well the main hose was that the cooling system would draw coolant from was. This radiator could be on its way out, it looks a bit underwhelming for how thin it is paired with the condenser. I felt air passing through the condenser when I was testing it and it was pulling through but I will still clean those fins. I did run vinegar through the radiator and the radiator only took half a bottle of a gallon of vinegar(which could indicate clogged pathways). I will swap radiators our for sure and this new one the owner got has the right lines for the transmission which 3rd time was the charm as the first 2 was wrong all the way around. Head was inspected and rebuilt by PHX cylinder head which I went through them when I rebuilt mine and they did a great job. I trust the job was done right and well.

Hey y'all. So I have had the pleasure to work on an 86 MJ with the 2.5L with an automatic trans hooked up to the trans cooler in the radiator recently and I'm kinda stumped with the cooling system at the moment. The owner never really took great care of it from what I can tell. So I had the owner get the head checked out because he overheated it and it is fine. here's what I have done: Cleaned radiator inside and out, put a new t-stat in due to the system not having one, Put in a new cluster along with sensors(will elaborate) Put in a NOS water pump due to wrong rotation water pump Cleared blockage from reservoir and cleaned it as well All that isnt new is the main lower and upper hose, I have bled the air out from the temp sensor and am still reaching over heating temps which kinda scares me but here is the deal with the cluster. I have a couple 5/6 clusters for the 86 year. I compared them all and installed the best one I had. Temp gauge works as I think it should because it pegs out both directions but seems to still climb. Climbs less rapidly than yesterday as I didnt have the system burped(oops) but now it mostly is and seems to still have an issue. Now here is where it gets weird, temp gauge climbs high and it seems the t-stat doesnt open up until what seems like it is past the point of no return. I do not have a digital thermometer to see what some of the temps are. It sounds like the water is boiling definitely but not traveling through at all and the radiator remains cool. I am wondering, is it the old main hoses caked with the bad crap thats failing?(lower hose has no spring in it) Air still trapped?(I didnt have this issue when I installed AC as the system is supposed to purge itself of air with the overflow) Bad radiator cap?(it is rated for 13psi but could not be holding any pressure). Any thoughts? I don't want to drop in the new radiator only to still have the same problem. And I also don't want the owner to throw more money at this but it seems possible for that to happen until this is correct.

Ew. Time stamp on the photos is very concerning for a year later and it looks to have been repainted from the lack of engine bay labels. Other than that it really is clean. Question is, what’s the underside look like?

Is the body ok though? Kinda looks like that corner is.

You’ll need an AX5 4wd trans to swap in place of your AX4. The only way you’ll get an AX15 behind your 2.5L is to find a Dakota with the same engine and swap that around.

Not necessarily. I’ll sometimes get this issue where I’ll be making a left hand turn and I want to get going and the engine will kinda stumble on itself until it finally gets the fact it needs to go.

How’s the TPS? Could be misadjusted and dumping more fuel in than the engine can adjust for.

That’s a spooooooky trip right there.
