  1. Thanks! I’ll check it out when I get back for vacation. Happy 4th everyone!
  2. I had the condenser out 2 weeks ago when converting R12 to R134. Its clean and can see through easily. No excess dust, grass or mud.
  3. 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.
  4. Go for it, more information isn’t going to hurt anybody.
  5. 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.
  6. 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.
  7. 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.
  8. 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?
  9. 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.
  10. 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.
  11. 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.
  12. The listing had expired, but I renewed it in case anyone wasn’t able to see the wheels before.
  13. 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!
