coolant

Hello team, I bought an LJ with 140,000 miles that looked super clean and without leaks. After driving it hundreds of miles home and a few miles in town, there is a clear coolant leak. It drips down along the oil pan and creates a big puddle. It does this even if it hasn’t been driven in...

Context: Had my 4.0 litre re-built couple years ago and since I've only put on approx. 10,000 Miles. Had my water-pump replaced late last year and a few weeks later started to notice some build up around my manifold bolt as picture. It stayed like this for a few months, meanwhile the Jeep...

Hi all, New to the Jeep world, having picked up at 2004 Sport recently. Have redone spark plugs, O2 sensors, rocket gasket cover, had the transmission serviced (And the next day had the hoses blow, and had to do again) and have a new solenoid pack on the way. Will be doing the solenoid pack...

I did it!!! I found my coolant leak!! Very exciting as a novice mechanic 😄 This radiator hose was very pregnant. So I’ll replace it tomorrow. But I still have questions. The leak was pretty slow. Lost 1psi about every 1-2 min and it slowed to a stop around 15 psi. She’s not leaking while...

Hello! Yesterday my TJ started leaking like crazy, what I thought was oil. I get under her and start ripping stuff apart to find out it was coolant mixing with road grim to look like oil. Eventually I take it apart and the waterpump seal went, so I just replaced the whole water pump. The leak...

I haven’t seen this specifically mentioned. If it has been then please forgive me. Im going to purchase a new coolant reservoir. The bottom of it looks disgusting from the previous owner. Im seeing pressurized and non pressurized. I never really new that was a thing. (Sounds dumb I know)...

Hey everyone, 88,000 mile 2006 TJ. Today when I got to work all gauges were normal and jeep was running fine. I shut the engine off and got out and heard dripping and steaming and saw white steam coming out of hood. So I opened it up and saw coolant had wet the bottom half of my engine bay...

Have a coolant leak posted a week ago or so. Dropping the Jeep off on the 4th to Jason at Absolute Offroad here in PHX. Filled back up with some distilled water and ran the car for 10-15 minutes since it hasn’t been started in week. It was DUMPING coolant after reaching close to operating...

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...

Hi all! Firstly sorry if im breaking any forum rules and any technical incompetence. I recently bought a year 2000 Wrangler, 4.0L straight 6. I’ve recently had a new radiator fitted but interestingly the mechanic never added a coolant reservoir. I only noticed because once when I stopped there...

My TJ has had every single component replaced in the cooling system within the last two years. Highest vein count Mopar radiator, Mopar water pump, stant superstar 195° thermostat (per Jerry's advice), new copper heater core, new hoses, new fan clutch (twice because the first one was lazy). I...

So about two weeks ago I purchased a used 02' Jeep TJ... Checked the oil the day I drove it and it was the normal used oil in need of a change. Coolant levels looked fine so I figured I'd take it for a few drives over the weekend I bought it. I drove it about 200 miles and everything seemed...

i have a 1999 SE 4 litre. my dash is throwing me a P0118 iv read online people saying there is only one coolant sensor but others say some older models can have two of these sensors? can anyone tell me if this is true? and is there a part number for this sensor from a reliable retailer online...

Hey everyone I need some help trying to find out where this coolant leak is coming from? Or at least I assume it is a coolant leak and that's what others have suggested as well. It's a slow leak but somehow it's coming out on the bottom of my engine and I cannot find the source. Here are some...

So I’ve seen similar post. I’m just wanting to get an opinion. I’ll post the video of the leak. It’s pink so I’m assuming it’s coolant. It looks like it’s coming from behind the belt. I gauge doesn’t show me over heating and even the the engine was running super hot. I’ve run it for about 5-8...

Hi all, I own an '01 TJ with about 85K miles on it. The car was in storage for most of the winter, and I slowly started to notice that my coolant was steadily decreasing even with no visible leak. I noticed that theirs a slight sweet smell when the heat is on, which leads me to think that the...

Hey all, I just bought my first TJ (4.0) last year at about 114k. Its been an up and down road needing a lot of work here and there but forums have usually been able to help me diagnose issues. The issue I am having right now is involving my coolant levels. My reservoir tank drains...

Went to run errands the other day and when I got out noticed coolant was leaking from the plastic petcock on the lower passenger side of the radiator. Turned it to the right to tighten it but noticed it was fairly loose, but stopped the leak. Finally got around to working on it and the freaking...

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...

I have a lot of improvements planned to make to my 97 Sport (Replace fenders, interior carpeting, repaint faded hardtop, etc.), and do some much needed maintenance on some systems. One of those systems is the cooling system which I am going to flush out. I had the engine replaced and they...
