I work in an auto shop and this liberty with the 3.7 cam in with overheating issues. The thermostat and pump has been replaced and the engine and radiator has been flushed. It is still overheating the fan blows correctly and it has enough coolant in it. The only thing I can think of is that even though the radiator is allowing water to flow through it. It is still clogged somewhere. I need thoughts ideas. Tips tricks anything.

 

head gasket? I had a 4.3L in a Chevy van that overheated and it turned out to be head gasket(s).

 

i have all these problems on my xj plus there is white smoke coming outta my exuast. i figured its my head gasket

 

Update. Ok. The radiator was clogged with shale. But get this. There is pressure on the lower hose where the thermo is. Even after you remove the radiator cap. I think the thermo is stuck closed

 

That would be the 1st automotive t-stat that seals pressure/water tight.

 

I even ran it without.the thermo. Still over heated... it basically had a new cooling system and it still over heated. Ugh. Stupid Cherokee wanna be.
