I went for a short drive yesterday and when I returned home my 95' Cherokee 2.5L was pissing coolant all over the driveway. I investigated a little bit and decided that it was most likely my waterpump. I spent all day today replacing it. The waterpump I bought was brand new and not re-built. When I got everything back together I started the car, reved the engine for a bit and again, coolant everywhere. I used the gasket that came with the new pump and applied High Temp. gasket seal to both sides of it. I am at a loss for what the problem could be. I also checked all the hoses and they are not the cause of the leak. It looks like the coolant is coming from or at least right near the waterpump but I cant see exactly where when everything is together. Any suggestions would really help me out. Thanks guys.

Also if I havent provided enough info just ask me what ever you need to know and I'd be glad to tell you.

 

If you have a pressure tester try and hook it up to your radiator and pressurize it with the motor off to rule out any bad hoses and see if you can find the leak. Hope this helps!

 

i havnt worked on a 2.5 but there must be a little hose you missed...can you take a picture?

 

I forget when they went to the open cooling system, but if yours is closed it sounds like you need to "burp" it. If yours is the open one, you probably need a new thermostat.
