check and see if your fans are working. if the fans are not working the there is no way to cool the water.

Recently thought I had the same problem w/my F-150, but it turned out to be a faulty sending unit, the motor wasn't getting too hot at all....

I am having the same problem with my f 150 98 what sending unit did you replace and also mine acts up with in two to three km of driving I shut off and start 10 sec later and all is fine replaced rad , water pump and the thermostat twice still nothing no coolant in the engine oil or coming out the exhaust and the heater core is not leaking could this maybe due to a blockage in one of the ports in side the engine itself how would i check
also have replaced the cap as well

I am just plain out of answers on this one and ford has no idea can anyone help !!!!!!!!!

Sounds just like the same problem I had w/my f-150. My engine was NOT actually overheating, the gauge just said it was (liar.liar).
IS your engine actually overheating? While I'm NOT a mechanic and can't give exact details, you should be able to tell after you raise the hood if the temperature is normal or really hot, and if the gauge says overhot and there's no steam coming out, well.....

The "sending unit" is what tells your gauge what to say, and they do go bad giving false readings. it's a small unit screwed into the engine block with usually one wire coming off it. I discovered this was my problem when my temp gauge went to "oh shit" in the middle of nowhere but the truck still drove fine all the way to town, and then didn't need any coolant or cooling of to continue!

Also check your radiator cap

I have a 93 Ford Probe. It is overheating and we have replaced the radiator, water pump belt, the cap twice, thermostat 3 times top hose and cleared the overflow hose that was blocked. After replacing the radiator and thermostat the car worked fine for several months then started to overheat when I turned the heater on. I don't have very good heat most of the time especially when I am going down a mountain. I noticed some kind of thick residue in the radiator and had it flushed. It still overheats. As far as we can tell the water pump is fine and there are no leaks in the system. No indication of blown head gasket or of a bad heater core. Could it be just a sensor gone bad??? Please help it's driving me crazy!!!!!

I am having the same problem with a 93 ford probe gt V6 I just bought the car so I do not have much history behind it. I have replaced the rad. and the thermostat. I have two mechanics telling me two differnet things. Although tthere is no milky white subtance showing up nor is there any water draining from tailpipe he thinks my heads were warped. The other mechanic thinks for some reason that the therm. keeps sticking
Good Luck I love this car I hope i can figure it out.

Water pump. Suggest you replace it with a new,not remanufactured unit. Also, replace the timing belt while you are in there. I have over 200,000 miles on my PGT and have replaced my water pump twice- once at 100K and again at 200k. Fairly common problem with the 2.5L V-6. Furthermore if you buy a new water pump as opposed to a remanufactured unit the second one is free as most new water pumps come with a lifetime warranty. Got mine from NAPA.
