If this is a 3.5 Lt., there is an air bleed on top of the thermostat housing. ( Top front of the motor) Loosen, but don't remove it. Let the motor run with full radiator until all the air is out an nothing comes out but coolant. You can also purge air out with the engine off by pumping up the coolant reservoir with a pressure tester with the bleed valve open. Then make sure the radiator fan(s) come on. If it runs hot out on the highway, have a mechanic check the gas in the radiator for exhaust fumes, which will indicate a leaking head gasket. You can buy you're own exhaust gas tester at a auto parts store. Good luck.

Bad fan, it's not kicking in when the heat rises in the motor!
