Hello I have a 2000 jeep Cherokee sport 4.0l and it is leaking coolant on the passenger side. It runs at about 215-210. I do not know what exactly is leaking.

Check all the hoses and the petcock drain. A lot of radiators actually split open at the seams so check over in the corners too

My 2000 just did this over the summer, it was a crack in the plastic radiator end. Leaked only while engine was warm though, cold it did not leak. Grab a buddy and a pressure tester kit from your local auto parts store, can borrow from Autozone with a refundable $150 deposit. The 2000 4.0 cooling system is rated at 18 psi. Pump the pressure tester to no more than 18 psi mark (to simulate coolant at operating temperature, do not do this while coolant is hot) and look for your leak, it should be visible. At 18 psi, my crack was spraying coolant out forcefully. Also check hoses if radiator not visibly leaking.

When I look down the engine bay it has some radiator fluid but when I put my hand down to were it is wet. I can't feel any radiator fluid leaking around the radiator or tubes should I take out the fans to get a better look.Originally Posted by Fred/N0AZZ
Where exactly is it leaking at on the passenger side.

Rent or buy a pressure tester and test the system. Autozone "rents" them. Then you can listen and look with the engine off.
