Question about 1999 Ford Windstar

1 Answer

Temp guage is moving to red (overheat zone) and not wanting to drop. It was dropping when almost on the red. Now it's not dropping back down to normal operating tempurature. I just replace the thermostat a few months back. So, this is a bit confusing. Thanks.

Your overflow cap could be your problem. The cap may no longer hold pressure like it should causing small leaks that you don't notice which will make the car run hot. Also it could be the fans not kicking on because of a bad temperature sending sensor. If these go bad, the temp switch don't know how hot the coolant is therefore it will not signal for the fans to turn on to start cooling.

    that might explain why it loses coolant as well. That is yet another mystery. Thanks again!

That code means cylinder head over temp and has nothing to do with the coil. Check for proper coolant level first. May also be blocked coolant passages in the cylinder head but unlikely. Or a faulty temp sensor

Charged the a/c to spec but air wont drop below 58degs

A/C is all conditional upon ambient air temperature. If you are in a high heat area and getting 58 degrees fah., you are doing great. Take it on the highway and see how much further it goes down. The temp. inside is all relative to the outside temp.. That is the science of it. Let me know what your guage readings are and the temp where you are and I can tell you if you are doing good or great.

The thermostat may be wearing out. A thermostat controls the engine temperature to keep it at a consistent temperature, The other fan will probably turn on if you turn on your Air Conditioner.

Will not put heat out. warms up when idle but as soon as i drive cold air comes out and the temp gauge drops to C

First check your coolant level and the level it protects your cooling system. Possible cause of the problem you are describing is the wrong thermostadt (i.e., missing the thermostadt or one that opens at too low of a temperature) would cause this. A temperary fix is to fix a piece of carboard across the front lower third of the radiator to block some of the air from cooling the coolant. You'll want to watch the temp guage when you do this so you can adjust the amount of blockage that works best for you; block more of the radiator or less depending what your temp guage shows. Block to much of the radiator and you can cause your car to overheat. Overheat your motor too much and you can really damage the engine.

The temperature sensor is located in front of the radiator on the passenger side. Replacements cost approx $25.00.
