  3. XJ Cherokee Technical Forum
    Not sure if this is related, but my XJ has been acting weird since I replaced a damaged exhaust header. 1999 XJ 4DR, 4WD, 4.0 with 150,000 miles. The exhaust header was cracked wide open near the collector and I finally replaced it after the noise was just too annoying. The old one was...

    Need a Jeep guru to help diagnose and resolve why this poor Jeep keeps losing it's cool? I have tried everything... to no avail. This video covers everything instead of having to read all symptoms and such... Is there an underlying problem I have missed? Or am I just pushing it beyond...

    Hello! I've been working off and on with my 2000 WJ 4.7 for a while, and recently moved to central Texas. First, the AC system failed, then I noticed the vehicle overheating regularly at highway speeds. It stays right at 210 in town, and no overheating issues until it gets out on the highway...

    Hello, I've grown up working on stuff, but am getting over my head on this project. I have a 78 CJ5 with at 304. Bought it used a few years ago. It ran fine until recently, and I've noticed the following issues. After I let it sit for 4-5 days, it won't turn over when I crank. Seems like...
  7. Engines & Drivetrain
    2000 Jeep Cherokee Sport (4.0 L, 4x4). I had my engine idling for about 10 minutes. I then shut it off. About 2 minutes after I turned it off, the coolant began to bubble out of the overflow/reservoir tank. It was fine when the engine was running, and the temperature gauge was sitting right...
  8. ZJ Grand Cherokee Forum
    This is a 96 Grand Cherokee, inline 4.0 six, near 200k miles, very few problems to now. Good old machine. Running real hot suddenly. Before the big write up, is there a definite test for bad head gasket or cracked head? Whole lot of R&R work there. Driving the Jeep and noted temp gauge at...

    Hey everyone! So I am new to the Jeep Forum website but i am here asking for help. Since around October I have been having issues with my jeep overheating, but it only does so on the highway. I've gotten my thermostats replaced, my water pump, and my radiator. My mechanic has also flushed...
  12. XJ Cherokee Technical Forum
    Due to recent overheating issues, I've decided to do some cooling system work. I believe my overheating problem may be related to the PO using Bars stopleak in the system and now that crap is all over in there. I think it's plugged up the heater core and probably the radiator to an extent also...

  16. ZJ Grand Cherokee Forum
    I'm stuck. The temperature gauge is reading high at idle, 220-230, but it isn't boiling--the upper radiator hose isn't even hot. Here's the whole story: the head gasket was leaking coolant into two cylinders, so I replaced it. In the process, I broke the top of the temperature gauge sensor...

    I have a brand new '16 JK Sport and the dash lights will light up and the TPMS sensors will read 0 after about thirty miles. The Jeep goes into limp mode and the radiator fan kicks into high gear. The Jeep has been in the shop for almost two months without a solution. The dealer has replaced...
