Coolant leak on 2004 grand cherokee 4.0

I found coolant dripping under the jeep right at the end of the oil pan right behind the crankcase pulley. hard to see if the water pump may be leaking, causing it to run down the front of the block down to the oil pan. with the serpentine belt & all the pulleys in the way, I can still see a small section on the front of the block which appears to be somewhat wet. However, I don't see a stream of coolant leaking while its running, but its directly underneath dripping on the ground. Do you think its the water pump or could I have a more serious issue?

    Thanks for your response. It turned out to be the water pump. I had gone back out to inspect & let it run for a while & finally saw a small stream leak here & there from the area behind the water pump.

Might be the thermostat housing to as its right above the water pump. the best bet would be to pressure test the cooling system and inspect to see where its coming from

Do I need special tools to change water pump on 2005 cadillac cts


  1. You'll need a tool to release the tension on the serpentine belt and when you need to put the belt back on. Regular standard socket wrenches will suffice for the rest.

Check that your hose clamps are tight and that there are no ruptures in the hoses. The best way to find leaks is make sure you radiator is full and run the vehicle until plenty warm and look for any spraying or dribbling. Be sure wipe off any wet hoses or parts of the engine before you start this test. It will make it a lot easier to tell where the leak originates.

Sounds like the rear main oil seal on your motor is leaking. In order for it to be replaced, the transmission has to be removed. Not an easy task for the backyard mechanic.

Water was found leaking from my oil pan and car is overheating. I have a 95 Mazda MX3


Is it leaking FROM the oil pan, or dripping OFF the oil pan?

If its dripping OFF the oil pan, that leads me to beleive you have a coolant leak somewhere. Check the coolant level. Check for leaks.

Check your oil, if the oil is milky/coffee colored. Or if your coolant looks kinda nasty, you may be looking at a headgasket.

if you have no external leaks then it sounds like you could have a possible leak into the oil system(you would have a milky look to the oil) or the head gasket may have a small leak and the car is burning coolant but not big enough to overheat yet.you should have the system pressure tested as you could have an external leak small enough that the heat of the motor could be drying it before it accumulates enough to drip off the motor and yet smell.also the heater core could have a small leak in it and not show a leak.

1999 Jeep Grand Cherokee, leaking coolant from what looks like the front of the oil pan, is that possiable?


not unless you have coolant in your oil(it would look like chocolate milk on your dip stick) its probably leaking out somewhere up above and dripping down to that spot where your finding it. wipe everything down, start the engine and watch it as it runs to see if you can identify its point of origin.my guess would be the radiator hose or the thermostat housing. hope this helps
