thermostat

Hey everyone, Here’s another TJ forum post about overheating at idle bear with me here. I’ve done research on what could be causing an overheating issue at idle and can’t quite narrow down what the issue is. Some Context: My Jeep when driving in stop-go traffic will slowly creep up in...

Since I have ordered the proper thermostat, where is the weep hole supposed to align? I noticed this big notch to the right and thought maybe there.

Hello all, I hate to make another thread about this but I am stumped. So I’ve been having a heck of a time diagnosing my coolant issues the last few weeks. Originally, I had a radiator fan relay circuit/ ECT code, which I fixed but now I seem to be stuck with this “thermostat inactive code”...

Hi, I've recently bought a new battery including a free install... while doing that, the shop noticed that my coolant was basically empty - no clue how I could miss that. Since I'm in thailand they quickly filled it with tap water.. at least it looked to me like that - I don't speak thai. The...

Flushing the coolant system, I first removed the thermostat. Did the Prestone, flushed, then Thermocure and flushed again. Three times I've removed/replaced the thermostat housing and it continues to leak. 1. Didn't use RTV for the flush. Noticed a leak but wasn't concerned since I was going to...

Hello, just got my first TJ 4.0! The forums have already helped me complete some repairs, thank you! Next on my to do list is to deal with some minor seepage coming from the thermostat housing… Is the consensus to go ahead and replace the whole housing or just the gasket once it starts leaking...

Unexplained coolant loss, no apparent leaks. 2001 TJ 181k miles 0331 head Overheated recently, didn't boil over but lost a lot of coolant. Culprit was upper radiator hose that split at the bend near the A/C lines and valve cover. After it cooled, I discovered the split when I removed the hose...

Ok all you cooling system wizards. What would cause a thermostat to lock open? I’m on my third Stant 195 now and befuddled.

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...

Hey guys! A buddy of mine has a OBD II Diagnostic tool, I ran my codes and I got these two: P1281 Thermostat Malfunction P0700 Transmission Malfunction Present I have a 2003 Rubicon, she's got over 153k on the odometer. I have also redone the entire cooling system. I hope you guys have some...

Wondering if someone can help me. I noticed the other day after driving the car a flood of coolant leaking from the front of the block. I can’t quite see where is is coming from. I initially thought it might have been the water pump, but there is no play in the bearing and it stopped leaking...

Prior to our Colorado trip I flushed my coolant and installed a new stant thermostat, temperature sender and cap. We drove the tj over 1000 miles to SW Colorado without issue. We have ran over 500 miles jeeping. Yesterday Morning I went to town and after about 5 miles I had an eng light. I...

Hey, has anyone had the cooling system replaced by a shop? I'm going to ask for an estimate and wondering what kind of price to expect. I'm talking about replacing radiator, water pump, thermostat, hoses, and a complete coolant flush. Plus whatever else I might not know about that should be...

The myth There's a huge myth out there that's been making rounds on the Internet probably since the Internet first started. Go to almost any car forum out there, and you'll find a slew of members who like to push the idea that making your engine run cooler is a good thing. Often times they'll...

This is my first post, so I don't really know if I posted it in the right catagory, but here it goes. My Jeep is a 99 Wrangler 4.0 5 speed. The previous owner has converted over to an electric fan. I've replaced the thermostat, upper and lower rad hoses, and even put in a new rad at the end of...
