I have a 1999 Ford Expedition AWD/4x4 4.6L engine. It is running hot. I do not have water in the oil or oil in the water. Does not have smoke coming from the tail pipe and runs smooth. I have replaced the water pump, thermostat, radiator, flushed the lines. I let it idle for 1 hour and it never ran hot but the heat never got hot inside the car. Also I drove it around the block and the engine ran hot. Had to pull over let it cool down then drove it back hot and it ran hot as I was pulling into the driveway. Help.
