Ok here goes.. I have an '04 ram qc 4x4 4.7... I know I should have gotten the HEMI.. Anyway, The thing is overheating! I have a long list of what I have done so far: New water pump, 180 t stat, coolant system flush, new fan clutch, and of course the infamous radiator cap!!! The truck is ok unless I put a load on it, such as, going up a hill or giving it full throttle.. I am lost! What else can it be? Radiator? How do u bleed the air out of these systems? I had a guy tell me through the bleeder screw and I had a guy tell me through the top hose.. any and all info is greatly appreciated! Thanks in advance... John

 

Radiator is partially clogged. Either have it professionally cleaned or just get a new one.

 

Another thing that you can check is the belt. Check to see if it is tight and not slipping. A loose belt will spin fine at low rpm's, but add a load and have to increase throttle and the belt might not be grabbing the pulley's and spinning them properly.

If this checks out, your back to the radiator or a hose that is clogged.
