Have you tried taking jeep to repair shop and have them pressure test your cooling system for leaks?

This is a similar thread so I'm not going to create a new one.

Over the last three months or so my coolant has been leaking into small, half-dollar sized puddles. On Thursday the temp went near 260o, after which I noticed the resevoir was empty. So I filled 'er up with half a gallon of generic coolant (no water). I checked it today and the resevoir is empty again. But I've seen no leaks since and engine temperature remains normal. Oil is fine, too. What's up? And how much coolant do I need?

Water pump.

I have the same prob. but I located mine. it is the upper hose nipple on the radiator it cracked and it seeps ever so slightly and nothing ever hits the ground. I just happened to be under her after a long drive and could see there was a wet residue on the bottom of my rad.

I had the same issue. I could smell coolant, but I never had a puddle. I failed to notice any frothy oil or milky coolant. My mechanic said my freeze plug was rusting out.

everyone could guess all day long but a LEAK DOWN test should be done next...............only way to tell whats going on inside the motor...

Just went thru this filling the resovior quite often and no sign of leaks and the oil fine. One day went to the car and a lot of coolant below. The radiator had a seam leak and was small enough that with the engine heating and cooling would leak out.

No sign of it on the driveway that I noticed to one day. Pressure test and wham found the leak in the radiator seam.

check the rad cap too, to see if its good. mine was bad and i put a new one on and i found a pinhole on the bottom of my lower rad hose once i had pressure.

Thanks for the advice!

i had the same problem,,,it drove me crazy for weeks,,,,
checked on everythin,,,,
finally found out tht it was on of the five water seals tht are on the driver side of the engine casing,..ull have to remove the whole manifold to reach it even the exhaust,,.takes time n i recomend tht u change all five,,,thy are round aluminum seals n thr r 2 sizes depends on ur engine modle.,, u wouldnt notice ny water cause its right under the beginin of the exhaust so it just evaporates.,,n whn u change em use high temp tested sillicon n dnt fill it up wit water till it gets tough n test it on high rpm.,,its a very nasty job n takes alot of time but its the only way..

I have an issue with my 2001 Cherokee classic with a disappearing coolant. I have been adding coolant, about once a week but then sh*t hit the fan so to speak on my way home last week. The Jeep over heated (thankfully in my driveway) and since then I can go through an entire reservoir worth of water after about 10 miles of driving. It is not leaking onto the ground and from what I can see its not going into the oil.

Thoughts?!

Welcome to the forum! This is a very old thread and I'm going to recommend that you start a new thread of your own. It will get you more accurate replies and people won't have to read through prior posts, which can lead to them moving onto others.


Good luck!

Tjwalker is right, this is a very old thread.

However, to answer your question... this is the most typical symptom of a cracked cylinder head. Unfortunately, 2000 and 2001's are notorious for this. I recommend getting it to a reputable engine shop asap. Good luck!

My coolant has been disappearing for 8 years, I have to add about a pint a week, I just live with it. Never see a drop on the ground.

On a positive note, you probably have no carbon buildup in cylinders 3 and 4.
