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: http://www.autopartsauthority.com/sp...ter-pump-1.jpg God Bless America, Bill O|||||||O mailto:-------------------- http://www.----------.com/ "Nick ------" <nixon8890@gmail.com> wrote in message news:1186257800.090185.206070@l70g2000hse.googlegr oups.com... > 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.

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.

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 Darrell |

After you stop and it cools for a bit, reach down under the nose of the
waterpump just behind the pulley to see if you can feel wet. If so, the pump seal is going.

Re: Jeep TJ, Coolant leaking from front oil pan gasket?
I still don't see any wetness around the water pump. In any case,
I'll try changing it and it's seal. I changed the oil today and did notice that it was very BLACK. I think it was changed around 4k ago, but I have never seen it this black. No signs of white or milky oil.

On a trip to maine it started overheating and when I checked the radiator fluid it was way low. I go hmmm, refill and boogie on down the road only to overheat again, find the fluid low again, and this time radiator fluid all over the engine and underside of the hood. Radiator cap - tight, but loosen and retighten anyway. Hoses - intact. Water pump - not visibly leaking. I refilled yet again and this time run the motor for a good 20 minutes looking for leaks and none to be found, so head on down the road and tan my hide if it doesn't happen again. I refill everything, run threw all the checks again and stand there watching the motor run and not leak while scratching my head. Finally I reach a foot in the door and start bringing the rpm up while watching under the hood. Nothing at idle, nothing at 1500 rpm, 2000 rpm, 2500, 3000 and bingo, the upper radiator hose starts emitting a nice little stream of fluid from a pinhole. New hose and I'm a happy camper headed on down the road. Happy that is until some Nanny from Israel loses control of her bosses rice burner and side swipes my nice purdy truck just outside of boston. Other than all that it was a good trip. The point is your water has to be going somewhere. It is either leaking from the hose, radiator, water pump, or head (does a tj have a water cooled intake?). If it's not escaping there then it's going in the oil (which you say it is not) or it's going up in smoke out the exhaust, which means maybe a bad head gasket or worse, cracked head. A bad head gasket could allow it to directly leak out of the motor as well. Don't just inspect around the water pump/radiator area. Look for water stains down the side of the block. If you are losing that much water each trip AND it was in the exhaust it should be fairly easy to tell, since your exhaust should be visibly white. Think fog coming out your tail pipe. Likewise easily visible in your oil. |
