02 grand cherokee over heating
I have 2002 grand cherokee that has been over heating. I changed the fan cause it quick working and made sure it kicks on when hot. But still over heating. Anyone have any ideas. I also changed the thermostat.

Was the coolant low when you changed out the thermostat?
May still have trapped air, rad cap, water pump or radiator.

Re: 02 grand cherokee over heating
Try putting a floor jack under the front and raise the front end. Let the vehicle idle with the radiator cap off. Watch for a good flow with no bubbles. Look for blockage in the radiator. If this doesn't work get a loaner pressure tester put around 10 to 12 psi on the system while running. If the gauge pulsates you have a blown head gasket.
