I have significant cooling leak on my 2002 Grand Cherokee. I have to fill it up with water before every use (thankfully I live in the south where it doesn't get too cool). I parked it last night and there was a huge puddle underneath this morning and the reservoir was empty. After filling it up, the dripping started again immediately without ever turning the engine. The only place I can see a drip coming from is actually near the bottom belt, but I can't see the source. It doesn't seem (initially) to be the radiator and all the hoses look tight/sealed. Any thoughts?

(Of note, I just came back from almost a year in Afghanistan and the vehicle sat idle almost the entire time).

 

I suspect the water pump.

 

im going to agree with dave. youll need a new water pump. lucky for you they don't cost to much

 

If u replace water pump I would recommend getting one with a metal impeller. Most are plastic including OEM. Advance has a pretty good pump....the impeller is black and looks like plastic but is metal.

 

Thanks for the feedback. I'm planning to go to work on this repair next week. I'll let you know how it turns out.

 

NAPA Premium is metal.
