    Hello! I have a coolant leak. I know shes not pretty underneath, blame NY. •2010 JK Sahara •3.8L V6 •79k •automatic Checked under the hood this past weekend for the first time in a bit and noticed my Coolant Tank was below minimum. Filled it up, drew a line on the tank. Drove 2.5 hours...

    I found a TJ about a month ago that looked like a decent deal. 4.0L, 5-speed manual. The previous owner saw fit to install aftermarket performance upgrades, including throttle body spacers. Anyway, it's losing coolant pretty quickly and I thought I'd ask here and see what y'all think. I have...

    Hi! I have a 2006 Jeep Grand Cherokee 4.7L V8 and am experiencing the below symptoms. Any thoughts/suggestions are greatly appreciated. Over the past several months I have noticed a "sloshing" sound which seems to be coming from the passenger side somewhere behind the dash. It sounds almost...

    I have a coolant leak behind the AC Compressor somewhere, its really tight in there so I can not pinpoint it. Any ideas? timing chain cover maybe? head gasket? 1. Water pump is not leaking, was recently replaced 2. No signs of coolant in the oil 3. Pressure test confirms that the leak is...

    I'm in the JeffCo area, just south of STL. I have had alot of health problems (kidney's) which have kept me from getting a simple t-stat job done. A friend was supposed to do it for me since I'm in alot of pain most times but he hasn't done it yet and I can't keep putting it off. My heater core...

    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...
  7. ZJ Grand Cherokee Forum
    I ran into an issue a few months ago that has me confused. Here's the story from the top (sorry in advance for the novel): August '18: I replaced the intake plenum plate/gasket on the engine (using the Hughes engine kit). The intake was removed and the coolant system was drained. When refilling...
  8. ZJ Grand Cherokee Forum
    I've had my jeep sitting for about 3 months while it was being worked on (no engine work) and I went to start it and it seemed fine at first. Then there was a horrid burning smell and a plume of white smoke coming from the tail pipe. I pulled it out of the garage to the outside where it was...

    At the same time, my AC stopped running cold and that distinct antifreeze burning smell occurred. I found out it was empty, so I refilled my coolant tank. The AC still isn't cold, and the coolant burning smell is still happening. Any ideas? Thanks in advance.
  10. 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...

    Hey guys, A few weeks ago I noticed a burning smell inside my car. I didn't bother with it until I hit the interstate a few days later and the cabin filled up with fumes. I took it to the shop and they replaced the water pump for around $350. A month goes by and I don't have any issues, except...

    This is going to sound backwards but, when I roll down my windows and turn off the blower motor, the engine runs pretty cool at 170 degrees (as read by OBDII reader). But, if I roll the windows up and turn on the blower motor (No AC, temperature set all the way to blue) the engine temperature...
  13. JK Wrangler Technical Forum
    Hello all, new member mostly due to panicking over some issues I'm experiencing with my 2013 JK. After googling "Wrangler heater problems", I'm a tad scared that I'm dealing with a couple thousand dollar issue. But I'm hoping that's not the case. I'm hoping someone can provide me with some...
  14. YJ Wrangler Technical Forum
    I got home today and saw I was leaking some fluid on the ground. It seems to be coolant and from what i could see, it was coming from the lower radiator hose at the block. I'm guessing something popped. I was driving it pretty hard before I got home, playing Mustang I guess. :oops: Any ideas...

    I went outside to check all my fluids today and undid the radiator cap and heard coolant/water leaking pretty good. Looked underneath the jeep and noticed it was coming from around the oil pan , probably above it. Put the radiator cap back on and it stopped, looked again and what looks like a...

  17. XJ Cherokee Technical Forum
    Need some clarification on which type and brand of coolant to use after flush. Here's some background. Back in January when we had a rare warm day here in Iowa I decided to flush the heater core and I now have very good heat in the jeep. Vents are another issue but not a priority at this time...

    I have a 91 YJ that the temperature gauge reads always cold. I replaced the sensor near the back of the block on drivers side. I tested the wire with a ground and gauge reads hot as it should. But when I put the wire cap back on and get the jeep hot, I get no reading. Is it grounded somewhere...
  19. ZJ Grand Cherokee Forum
    My 96 Jeep ZJ with 136k miles has been working fine, except for sometimes cutting off while starting (thought this might be the ignition switch as fiddling with it gets it working again). Had some body damage to the front right corner, driven with it for nearly a year without major issue...
  20. YJ Wrangler Technical Forum
    So, I'm in the process of replacing the Heatercore, Waterpump, and Radiator with aluminum. The water pump recommends extended life coolant. Would I have any problems changing over to yellow extended life coolant after several flushes?
