Re: Any Ford Mechanics out there?
I'm not a mechanic. But the basic diagnostic rundown would be something like:
Verify the sufficient amount of coolant. Then verify the correct ratio of water to coolant [50/50] using a hygrometer. [don't overlook this as insignificant or too basic]
Verify the accessory belt is not worn, has no oil spilled on it and properly tensioned.
On to the thermostat check. With the engine at operating temperature touch the upper radiator hose. If it's not hot, then it's worth assuming you need to replace your thermostat. Find your part # yourself. Then grab one. If the hose is hot but seems to be collapsing, then replace it.
If the car only begins overheating when stopped and idling but seems to cool of a bit when driving then you can move to a fan malfunction.
I'm inclined to think that the A/C and the overheating are separate issues. Unless your belt needs replacement. But then you'd have other accessory related issues as well.
