Just installed a new ZJ fan clutch a few days ago, definitely not that. Anyone know a way to test the water pump flow? The water pump will be a ways down the list of things to try due to cost. That being said, do they make a high flow pump? I’d prefer to keep it on the belt and not switch to electric.

Go for it, more information isn’t going to hurt anybody.

Approx. 150K miles. Engine is clean aside from some oil in driver wheel well due to PS hose that was leaking. Where did you find an 18psi cap? Most of what I’m seeing is 13psi, with the occasional 16psi. I have a 9x11 transmission cooler that I’m gonna hook up later this week. We will see if that helps. The efan is pretty much on all the time because of the AC. Yes, PO replaced rad. and water pump. I’m assuming he delt with the same stuff I am because he claims it never over heated on him. I kinda believe him because i installed the xj gauges, he only had dummy lights.

The rad cap looks to have been replaced when the PO replaced the radiator. I don’t know the “pop-off” pressure of the cap (to use a carb term). When I got home today, the truck was registering 195-210. I parked it and let it idle to see how hot it would get with no ac and a pretty cool day (for TX). It got up to the third tic-mark again after several minutes so I opened the hood, wondering if it would help to get the hot air out of the compartment. It did not. Later tonight I’ll put it on an incline and try top burp the system without getting into the t-stay again.

It’s not a Mopar, but I did replace it with a brand new Mr Gasket 195* t-stat last week when I did the flush. I’m hearing some bubbles when I turn it off so I think I will try to burp the system and see if that does anything. Thanks for all the input so far.

Do you think that is enough of an upgrade? This doesn’t happen sometimes, it happens every time I drive it. Once it gets up to operating temp, even just stopping at a red light it will climb 10-15 degrees. Is there a way to check the engine for blockages? Could the PO have installed the water pump wrong?

Yes

Hey guys. Ive been pouring over this website (and others) for a couple months now looking for tips on bringing down engine temps. On the highway, the trucks stays around 195 just like it’s supposed to. When I kick the A/C on it will jump up to 210, no big deal. Once I hit traffic it will climb pretty quickly, faster with the A/C on of course. It’s never spewed, but it will hover between the final tic-mark and the red area (I’m assuming ~250ish). It has a new 2 core aluminum radiator, new ZJ fan clutch, new 195 t-stat, e-fan works great, new GMB water pump, new Zerex coolant with 60% water because I live in TX, and new coolant sensors front and back. I flushed the coolant recently even though it was super clean, thinking it could have had a blockage somewhere. I backflushed the heater core and pulled the t-stat so that everything got properly cleaned. I’m at a loss of what to do now. Would hood vents do the trick by evacuating the hot air? Do I need to go 3 core + triple e-fans? I just got back from a test run after installing the ZJ fan clutch and the same thing happened. It’s only 83 right now and overcast. If it’s heating up now, I don’t stand a chance once it’s in triple digits and sunny. Is there a way to tell if any passages in the block are sealed without tearing the engine down? I’m all ears. Thanks everyone.

You can smell it from a ways off. I left it open to air out for days and it didn’t help much with the smell. I need to open it back up, clean it with some soap and water and let it air out again. It’s supposed to be mighty hot and dry this week so maybe I’ll do it sooner rather than later.

I just finished converting my ‘92 over to R134 yesterday if you want some help on the write-up. I pulled all the hoses and the condenser, flushed everything including the evaporator and installed new expansion valve and accumulator. I also drained the SD709T compressor and replaced it with Ester oil which is cross compatible. Rented a manifold, vacuum pump and flush gun for the project and got it all vacuumed down and refilled without problem.

Cool, thanks Pete. First is the camper when I picked it up in Denver. Second is when I got it home and started cleaning it. And last is me airing it out. I’m waiting to roll on some Raptor Liner in the bed before I put the camper on. I’ll update once I do!

Does anybody have tips on how to bastard pack it so I can gain about 2-3 inches? I would maintain a better ride with longer leads correct?

Looks like this really could be an MT pack.

Ok thanks. I’ll take a pic in a couple hours.

Should have arranged the pics better, sorry about that. Pic 1: track bar Pic 2: adjustable track bar? Pic 3: UCA perch & slag from torch Pic 4: LCA drop bracket?

Hi everyone, Ive been lurking for a long time and getting a bunch of questions answered so this will be my first question. This first part is just some back story if you want it, otherwise skip ahead. I’ve been debating on which lift to get for my Manche (3.5 or 4.5). While under the truck doing some homework, I saw a few things that look out of place. It appears that it has had more suspension work done than I previously thought. I knew it had WJ L and UCA’s and a WJ sway bar plus a 2” lift puck. What I’m seeing now is the UCA perches have been hacked up and the LCA may have a drop bracket. I attached some pics so hopefully someone can school me if I’m an idiot. I’m looking for some pics and/or specs for stock suspension components along with some answers. Is my UCA perch mangled for a reason? Is that really a drop bracket on my LCA? Is my track bar factory or adjustable aftermarket? Whats the drop on an OEM pitman arm? How can you tell the difference between a leaf pack with an AAL vs an MT leaf pack? And finally, does this make sense to anyone or am I just rambling? Thanks!

Oh man, I almost forgot! I finally found a Wildernest! I drove from Austin to Denver to pick it up. It’s in good shape, but I want to do a solid update to it before I put it on the Jeep. While that’s going on I’ll spray in a bedliner and swap my tailgate out with a spare I have. I’m trying to upload some pics. It I’m sized out. I’m on my phone and can’t shrink the photos so it’ll have to wait.

Finally, I ordered a Smittybilt front bumper and winch from Quadratec. It was a pretty decent deal when bought as a package, bumper, bull bar & winch all together. Sure it’s not a Warn, but it was cheap. And finally got the windows tinted (a necessity in TX). The Jeep has OME shocks from the P.O., but suspension wise it’s ZJ coils with 2” spacers and ZJ lca’s, uca’s and sway bar. My next plan is to get some RE 3.5” coils and install some 1” shackles in the rear to level it out. I found some Jk wheels on CL I want to get as well with the factory 255/75r17 mud terrains. So in the near future I’ll hopefully get some proper springs and level out the lift, get some adapters & install the wheels and, if I need to, trim a little around the fenders.

I also ordered a hitch from Krusty and installed it. Looks great and is more heavy duty than I expected. I put it on by myself but having an extra set of hands would have been nice. I found an HO cluster from an XJ in the tool box along with a bunch of spare parts so I swapped it over. Having a ‘92 does have its perks; no speedo cable! I swapped over 2 pigtails and it worked great (aside from replacing the temp & oil sensors). I gained 50k and lost my gear indicator though.

So I’ve been doing a few things to the Jeep, with a few more planned ahead. I pulled the interior out, cleaned the carpet, doors and panels, laid down some Noico sound dampener and installed 6.5” speakers front and rear.

Austin. Just bought my 1st Manche a few weeks ago and loving it. ‘92 Pioneer 4x4 4.0. Paint is faded but getting everything else the way I want first.

Thanks for the heads up 89, a bedliner is not my first choice because of cost. I’ve also been thinking of “industrial” paint for tractors and such, just don’t know where to get that done and am never painting my own rig again. Anyways, here’s some pics. Nothing special.

Hi everyone. I just bought my first MJ 2 days ago and I’m pumped. I live in Austin TX and wanted a cool, fun project to take off-roading, camping, haul the canoe, etc. I had been looking for a few months but everything around me was a short bed and I wanted a lwb. Tangent: I couldn’t find anything locally so I looked abroad. Found someone selling a wildernest in Spokane and a lwb 4x4 in Missoula. I figured I could fly into Missoula, buy the Jeep, drive to Spokane, stay with my family, buy the wildernest and then drive home. The MJ wasn’t perfect, but it was what I wanted and I REALLY wanted the wildernest. But I got distracted and took one last look locally. That’s when I saw it.... Continue story: I got on CL and finally found my unicorn in south TX. 1992 Pioneer lwb 4.0 4x4 auto (my wife refuses to drive standard). I wouldn’t have to deal with renix, there’s 0 rust in south Texas, body was pristine; I must have it. So we took a trip to the beach and, on the way home, would detour inland to check it out. It was beautiful! Original paint is well worn but there, no dents, no dings, no rust, great interior, AC, cruise control, 155k original miles, turbine wheels, it was more than I could have hoped for. I looked underneath and it kept getting better. OME lift, MT springs, no leaks and again, ZERO rust. I had to have it but I wanted to get a good deal so I played ignorant, like I didn’t know what this guy had. I started low, knowing he would say no. He stayed strong but I eventually got him down below what I was expecting to pay. I was elated. We signed all the paperwork and I was on my way. Quick stop to fill up, back on the hwy, cruise set to 70 and off we went for the 6 hour trip home. Now is time for the fun to start. Its in great shape but needs a few things, so I’m gonna start cheap and work my way up. AC needs a recharge because summer is coming quick in TX. Might also get the windows tinted. Soon though will hopefully be some new tires, bumpers and a paint job. I really dig the eggplant color it has but I’m also interested in bed lining the whole thing for durability (open to suggestions). Photos to come later. Thanks for any feedback. TL:DR bought my first MJ!
