Question about 1999 Ford Expedition

1 Answer

I have a 99 expedition which is still overheating. I first changed the thermostat. It did'nt solve the problem. Then, noticing that the truck heater didn't work I concluded that the radiator was plugged and had it replaced along w/ new upper and lower hoses. I drove about 15 miles that day and everything seemed fine. But then, today it overheated again. What should I do next?

For one you need to get any air out of the system, this sounds like you might have wasted alot of money parts replacing, you will need to find a shop that can pull a vacuum down on the coolant system, and fill it, this will ensure that you do not have an air lock inthe coolant system, that is where I would start with if this rolled into my shop... this will also let you know if the coolant system has any air leakes.

Good luck

1997 ford expedition overheating problem truck warms up fine heat works good then heat goes cold and temp gauge jumps from normal to overheating i have changed the thermostat twice water pump fan clutch...


This might sound like too simple a solution, but after owning 5 expeditions, I think I may have an idea.

It is possible that the cooling system is simply not full of fluid. If, when changing the thermostat twice and other service, the system was not sufficiently bled or burped, this can happen. What happens is that people do these repairs, and then fill the radiator, but fail to completely flush the cooling system. My son had the exact same problem on his Mazda 3 (Mazda was owned by Ford then), and flushing his cooling system solved his problem.

Think of it this way: If your heater works fine, then goes cold, that usually means the heater coils which the air blows over have no hot fluid in them. As for overheating, your thermostat opens when your engine reaches a certain temperature with the intent to exchange the too-hot fluid with water cooled by the radiator, but if there is only air, or insufficient fluid in the engine after the exchange, you will overheat.

Ask your mechanic to flush/burp the cooling system completely. I hope this works.

My 99 ford expedition is overheating. We've put on a new water pump, new serpentine belt, new thermostat. What else is there that could be causing this problem.


check the cooling fan if it's just clutch fan the clutch is probably bad if it's an electric fan check and make sure the fan is comming on

make sure that there are no air pockets in the cooling system this can cause cold air and overheating. if this doesn't work you might have to replace the water pump.
