sounds like a head gasket has gone bad. Check the oil if it is milky then your head gasket need to be replaced on your car.

yeah, and your heater core.

Oil is clear. Now what?

It's probably your heater core.

you can bypass it if you live in a warm climate.

Replacing it ia a PITA, if you have a shop do it, it'll be expensive (especially for such a small relatively cheap part -it's all labor!)

Before taking the job on, you should get it checked out, in any case. no use spending money on parts you don't need.

Yeah but the car overheats even if the engine is cold, after travelling a couple of miles. Would the heater core do this?

If it's blocked, TOTALLY.

No fluid would be getting back to the radiator.

If you take it back, they should give you free labor, AT LEAST. you've already spent a ton of money and not had results.

If they don't give you the labor back, consider going to small claims court to get your money back, and take the car to a Ford Dealer.

Is all of the air out of the cooling system ? Maybe it just needs the air blead out . If their is a air pocket in the system it will cause the car to over heat as well . Just loosen the bleader nut and run the car . When no more air bubbles comes out it should be fine . good luck .

yeah, hadn't thought of that. That gave Dewd fits for months.

i could be wrong but im pretty sure that even if the theromstat is closed the coolant should be getting to the heater core other wise major pressure would be building up in a system that doesnt allow any flow yet the water pump us pumping especially when you first start driving and it hasnt open up and you are going say 35mph. also another way to just check to see if the themostat is working right you should notice flow in the radiator once the car gets up to normal running temp.

If it was installed wrongly, it can impede flow, without cutting it off, the effect is still the same.
the air bubble can get picked back up by the system at random intervals.

Eventually though, something will have to give.

true but im just saying that i believe the delivery to the heater core is a by-pass so that when the thermostat isnt open the coolant still moves just not through the radiator. now if your not getting heat when you turn on the heat then your heater core is mostlikely blocked. i mean there could even be a slight chance that your water pump is messed up too.

yeah, but at 90,000 miles?

if whoever had it 1st never changed the fluid, I'm betting heater core's blocked.
