    2003 4.0 TJ Starts Running Hot

    Got the TJ in late summer ‘21 and flushed and changed out entire cooling system except fan clutch. Pretty much all Mopar parts and G05 coolant mix. It was running hot when I got it. Since then, it has pretty much run 195-200 anytime I am on the road and might get to 205-210 when doing traffic or...

    TJ running hotter than usual

    My jeep is a 2004 4.0 auto. I have owned it for a year so far. Since day one, once warmed up, temperature gauge will read at around 195-200 and wont fluctuate AT ALL whatever the situation ( heat, cold, AC on, traffic…) Last week I replaced TPS and upstream O2 sensors (Mopar) and added grille...

    Unexplained coolant loss, no apparent leaks. 2001 TJ 181k miles 0331 head Overheated recently, didn't boil over but lost a lot of coolant.

    Overheating issue

    2005 Automatic Jeep SE 65k miles I made a post about this about 2 weeks ago but I want to somewhat follow up on recent events.

    Transmission Cooler Needed?

    2005 Auto Jeep 4.0 So, I am new to the Jeep life. Been going through the forums a lot and noticed that a lot of people have transmission coolers because the 42RLE Transmission tends to do a poor job when you’re on the trails. With that being said, right now I’m using my Jeep as my DD because...

    How accurate is the engine temp gauge?

    Just driving around and the indicator line is slightly past the 210. Don’t know if it’s overheating or if this is something that’s normal. Mind you, it is 95 out right now but I don’t know if that plays into this.

    A myriad of problems

    Hey everybody, hope you are all doing well. The TJ overheated for the first time today while on the highway, pulling a couple ATVs, and it was about 110 degrees out. I know a pretty heavy load but it's done it going on 3 years now no problems. So I got the check gauges warning and saw the temp...

    Overheating at low speeds and idle

    02 TJ is overheating at an idle or cruising around town under 30mph. I have replaced the fan clutch with manufacturers fan clutch, replaced thermostat, filled radiator with coolant, checked coolant. None of these have fixed the problem. What is my next course of action? I was wondering about...

    Overheating issue continued (only when turned off)

    I’ve had a problem with my 2000 Jeep Tj 2.5l overheating when I turn off the ignition. When I’m idling, revved up to high rpms, on the interstate, or any other situation where it’s turned on, I have zero issues with overheating. It stays right under the middle 210 mark (so maybe around 180-190)...

    Advice on coolant system and damage

    Okay, so let me start by saying I don't know much about fixing cars, but consider myself handy and want to learn more about fixing them, and having a 4x4 is fun. Two weeks ago I picked up a 5-speed 1999 Jeep Wrangler with a 4.0L 6 cylinder engine with the intent to work on it. The previous owner...

    Angry Bird Grill

    I installed my angry bird grill last fall and have had no issues until the last month with the weather being hotter. I was told that the grill may be contributing to issues I've had with overheating and my temp gauge acting screwy. Was told the grill could restrict air flow. Has anyone else with...

    Hi all, I recently purchased a 5speed 02 Sahara 4.0, and it runs great, but if I pull the ebrake while at a stoplight or waiting in a parking lot, etc., it starts overheating. Doesn't do it when I'm idling at a light with the brake down though.. Anyone experience this before? Is there something...
