I recently purchased this vehicle and immediately had overheating problems. I started with the basics and am still having issues. I replaced thermostat flushed both radiator and heater core. Replaced fan clutch and still overheating. I have noticed that the fan clutch does not engage like it is supposed to. Do I need to move the radiator closer to the fan? Just not sure whats up. Any help or ideas would be helpful. Thank you.
Also it only overheats at slow speeds or climbing. Has 6 inch lift and not sure if the engine was moved from original location.

 

I would guess your radiator has some serious blockage . If it is original.


If you have a good radiator shop close it might be worth a trip either have it cleaned or re cored if the tanks are still good.

 

Also, get a Aisin Fan Clutch. I don't trust those other suppliers.

 

If you live down south get ya a 3 core radiator and a lower temp thermostat while your at it. Make sure your top radiator hose isn't curved up I've always been told that will cause probs.
Edit: just saw that it was lifted has it had the radiator droped ? And dose it still have both peices of the shroud? If its all suspension lift disregard those questions
