94 Cherokee XJ Coolant leak
I've got an intermittent, minor coolant leak on the driver's side of
the 4.0L. She's got about 118K on her. Every so often, I'll find a
tiny puddle (silver dollar size) of coolant under her on this side.
I cannot find any hose that is the culprit. I know there are some
freeze plugs over here, but visually they look ok, near as I can see
(not a lot of room to get in there). I'm using the difference between
"full" and "add" in the coolant bottle over the course of a week.
Before you ask, no white smoke out the back, so I don't think I'm
burning it, and dipstick looks like pure oil.
Aux. fan is running when AC kicks up, so no boil over. Replaced all
hoses, water pump and thermostat about 6 months ago when the water pump
went.
It has me stumped. Any ideas?
Thanks much.

Re: 94 Cherokee XJ Coolant leak
You should see a little corrosion wherever the coolant is leaking from.
Trying taking it for a short drive and getting the engine good and hot - run
the AC, and take it home. Make sure it's hot, and open the hood and look for
a leak try having someone rev the engine while you look, and also try
shutting off the engine and re-checking.
Failing that, you can get a cooling system pressure tester for around $20 at
an auto parts store. Basically, it hooks up where your radiator cap goes and
pressurises the system. It's got a little gauge. If it's got a leak, it'll
leak when you pump it up.

Re: 94 Cherokee XJ Coolant leak
It's not the normal condensed water/ice melting off your Air
Conditioner's evaporator, is it, passenger side firewall, while parked?

Re: 94 Cherokee XJ Coolant leak
my 96 jeep just went through the same thing and I had a clogged radiator
but yours doesn't sound that bad. Does it only leak when its cold or sat
for a while? It might just be a clamp thats not tightened well and it only
leaks every so often when the car is cool.
