Q: Expedition overheating

asked by on

My Ford expedition is overheating, the radiator has been fixed, the thermostat has been replaced and then removed, the antifreeze level is fine, there are no leaks either outside or inside the engine, the cooling fan works fine. What else could it be?

My car has 100000 miles.
My car has an automatic transmission.

Be sure the engine is actually overheating and you are not looking at a faulty temperature gauge reading. To determine the actual operating temperature use physical temperature measurements at the sending unit. You did not mention the status of the water pump (drive belt, pump impeller, etc.). Of course, check to be sure you have a functioning water pump.

If engine timing is too advanced, whether basic timing (at idle) or the advance mechanism, that can cause overheating. Another possibility in your circumstance with a 17 year old engine is that the cooling passages could have a blockage. Other obvious things to check are low engine oil level and dragging brakes.
