Jeep Cherokee Coolant Leak

Hello All,

Quick question – I have a 95 5.2L Jeep Grand Cherokee, car has been
amazing - 210K and very little has gone wrong (other than new rotors
far too often!). I give it a good bashing off road once in a while and
after the most recent session it has developed a coolant leak.

I have been having leaks in the past, mostly the occasional leak from
the header tank that I put down to an intermittent blockage in the
system, and a full flush seemed to solve the problem.

However this time it seems different, the leak ONLY occurs when the
engine is switched off after a period of running (hence the system de
pressurized) and then it throws out at a fair rate – about a liter of
coolant. It appears to be coming from around the water pump but it is
difficult to see exactly where the leak is from. I drove 150 miles
yesterday on the freeway and it never looses any coolant when the
engine is running.

Also it only chucks out coolant when the engine is stopped about 60 %
of the time.

I am guessing due to the fact that it is only leaking when the system
is de pressurized that this might be a water pump seal problem? Hoses
look fine.

I would tackle this myself but unfortunately had all my tools stolen
some time ago, and now also lack the space to work on the car – so
will have to take it to some back street shop – so wanted to get a
decent idea of what it might be, before they start trying to sell me a
new back axle etc…

Any knowledge, ideas etc.. would be most greatly appreciated.

Thanks to all

I'm having the same exact problem with my 1998 Jeep Cherokee. Never
really had a problem before with it, took it into the shop in Nov -
they replaced all the fluids and then the next day I had the car parked
while running errands and there was a big spill of coolant. I called
the dealorship and they saidit was probably overflow from filling it up
too much, not to worry. But it's been leaking about the same as your's
when ever the car is parked and stopped.

I know I need to get it fixed but want to get a good idea of what it
might be before I take it in...

Also - we're having a DEEP freeze right now, and the heat is not
working! I haven't really had to put the heat on until a few weeks
ago, but the blower was blowing but no heat was coming out. We heard a
bit of a slushing noise when we made turns in the car... Yesterday I
went out for 30 minutes and couldn't get any sort of heat until I
pulled back into the driveway. . It would get warm for a minute then
blow cold air again. The front window frosted up, on the inside and
the outside!
Did you ever find out what was going on with your jeep?

THanks!
