I NEED HELP FAST!

FORD TAURUS

I have a 97 Ford Taurus GL with a 3.0L OHV engine. I just had a new radiator and thermostat put in because there was a leak in the radiator, the engine was overheating, and the heat was blowing out cold air, and also the coolant was flushed out as well. But the problem is that it was blowing out hot air a few times since it got fixed two weeks ago now its blowing out cold air again what do you suggest the problem is. I don't have money to keep spending on repairs like this considering the mechanic said it was only the radiator that needed to be replaced and it cost me nearly 800.00 to get that fixed.

Bleed the system of air, there is probably a air bubble causing the coolant not to go through the heater core properly.

800 bucks for a rad and thermo? OUCH, that's large. Check your heater core piping for blockage, there's a bypass line back there that has caused problems before concerning heat output. The core gets crap in it, heat goes away. People flush the system, but the core doesn't get the full benefit due to the design, the blockage just re-routes the flush. The fix is to disconnect the lines and flush the core directly. If this isn't the problem, check the operation of the blend door, in fact check it first.

Your lack of heat could be caused by a low coolant level as well. Make sure the coolant is at the proper level.

My '97 developed a mystery coolant leak I couldn't track down. Turned out my coolant reservoir had cracks all through it. Didn't find it till I bought the special adapter for my pressure tester.

Your coolant reservoir is pressurized just like the rest of the cooling system (unlike older vehicles). Make sure it's not leaking. Hope this helps! :D
