Are you sure it's not air locked? Run it with the rad cap off and keep watching the water level. It might go up and down and then finally drop. Maybe even try letting some air out of one of your heater hoses if you can.

OK you have done the engine side of things. If you have an electric radiator cooling fan make sure it comes on when radiator is hot, if not the fan motor is caned or the thermostat switch is faulty. Sometimes the fan motor is supplied by a fused/relayed circuit in which case these items will also need to be checked. Check that not only does the top hose from the engine to radiator get hot but that the bottom one does too. If not this would indicate a blockage perhaps in the radiator core due to sludge. If full of sludge give both ends a flush out with a high pressure hose. Like wise do the same with the bottom hose back to the pump. If the water is circulating and the radiator fan is working then the normal cooling system is working as it should. f the engine is running hot one last thing is to find the EGR valve and check that it is opening as it should. If not the combustion temperatures go very high. One indicator of a hot engine is blue/glazed spark plugs so take one out and check it for signs of hot running. If hot then look to clean the EGR valve and associated exhaust gas feeder pipe with frayed cable, cloth and and carb cleaner spray.

SOURCE: electric fans comes on and
Your vehicle is equipped with two cooling fans. There are also two cooling fan relays. One relay turns the fans on low speed the other turns them on high speed. They should BOTH be running anytime the A/C is on and the A/C compressor is engaged. If they do not, then there is a problem with your fan circuits, fan relays, The wiring to the fans, A/C request data going to the Powertrain Control Module (PCM), or the relay control circuit between the PCM and the fan relays.
The only way to properly diagnose this problem is with a scanner that is able to command the HIGH and LOW fan relays on and off so the ciruits and fan motor operation can be verified.
