I had a 4.0 a while back that had all the impellor bades on the water pump rotted until they were almost flat! Had to be over 2500RPMs to get the slightest sign of circulation , at idle no circulation at all. ......Maybe you can remove t-stat & see if you have any coolant flow & if it changes off-idle?
Is coolant level the same or is it loosing some? Pump would be the last thing I would try but considering the mileage it's a possibility. Something simples as a radiator cap or air in the system can also cause overheating, if you aren't loosing coolant. Was the original issue just overheating or leak?
the problem is just over heating,no leaks,pressure builds in radiator and blows out if i leave cap off and would probably build with the cap on and blow a hose or worse,how do u bleed air out of the system?thanks
thanks i think that is my next thing to try before pulling water pump my sad guess is the blades may have rusted away on the pump dang!
