Jeep TJ, Coolant leaking from front oil pan gasket?
Hi Folks,
My 2000 Jeep TJ 6CYL 4.0L has been leaking coolant for some time.
Originally, it appeared to leak from the top of the radiator. Given
this, I replaced the radiator. Then it started leaking from where the
lower hose connects to the radiator. I then tightened the hose on
with hose clamps. Now its still leaking from what appears to be the
front passenger side of the oil pan, between the gasket and the bottom
of the oil pan below the serpentine belt. I'm pretty sure the leak
isn't dripping from above hoses.
The Jeep has almost 150k miles on it. I suspected a bad water pump,
however there is no coolant leaking around the water pump gasket. I
pulled the oil stick and confirmed the oil is brown, not milky white.
When I changed the oil it didn't appear to have coolant mixed in. The
cylinders are not misfiring. It's leaking about 1/3 gallon of coolant
a drive.
Does anyone have suggestions on the root cause? I was going to
replace the water pump and thermostat, but the symptoms don't lead me
to believe they are at fault. It seems like an over-pressure problem.
Any insight is appreciated.
Thanks so much,
Nick

Hi Nick,
I think you'll find it's leaking from the water pump, from underneath
look up following the lower hose up to the pump and at the shaft you will
see the stains from coolant leaking from the weep hole:

Re: Jeep TJ, Coolant leaking from front oil pan gasket?
Thanks Bill. Other people have suggested the water pump. It's
possible that the engine is evaporating the coolant drip trail, so I
can't see it.
I'm going to replace it, the thermostat and serpentine belt all at the
same time.

possible that the engine is evaporating the coolant drip trail, so I
can't see it.
I'm going to replace it, the thermostat and serpentine belt all at the
same time.

Re: Jeep TJ, Coolant leaking from front oil pan gasket?
Thanks Bill. Other people have suggested the water pump. It's
possible that the engine is evaporating the coolant drip trail, so I
can't see it.
I'm going to replace it, the thermostat and serpentine belt all at the
same time.

You might want to clean everything as best you can, then get a
pressure tester and look for leaks. It goes on in place of your
radiator cap and has a hand pump to pressurize your system. Places
like AutoZone, etc. sometimes loans them out.
Good luck
