NO HEAT 97 FORD TAURUS
|
Sign In
|
|
I have a 97 ford taurus 3.o overhead 130,000 miles and no heat I've had heating core replaced, system and core flushed and back flushed and thermostat replaced but I only have heat when going above 3000 rpms and it is warm not hot. Only other things can think of would be water pump but car isn't overheating, electronic blend door actuator or the steel lines between the engine and heating core are clogged though doesn't sound likely.. I'm researching like crazy to get this fixed so i can drive my kids around wout freezing or worrying about vision impairment because i cant defrost my car but im a single mom who knows nothing about cars and im running out of money... please help me figure this out?

Without knowing all the details I would think if you had a shop replace the core for a heat problem, the ball would still be in their court to get this system working. A heater core on a Taurus is no small job...
I would 1st make sure the T stat is working. If it was stuck open, that would cause this problem. If thats ok, a heater hose can be removed fromt the pressure side, put in a container to keep from making a mess and start the car, there should be good coolant flow, if there is, that indicates the pump is good.
If all that checks out then you would be down to verifying if there is exhaust gases getting into the cooling system, a blown heat gasket will also cause this problem..

Pill to check but water pump impellers may be at fault??

I agree with Tom. I owned this same model and went though the same issue and logic about the car not overheating or running hotter then normal. Water pump was the issue. It was corroded away enough to prevent proper coolant flow to the core but not enough to cause a engine temperature issue. Have your new pump handy when you remove the old one to compare the impellers. I didn't the first time I did mine and reinstalled a bad pump because I couldn't tell the difference without the new pump to compare to.

I have seen water pump impellers rot off very rarely but when I have seen it, it was on a Taurus.
