Just had this problem my self. I have a 2002 Ford Windstar LX. I was leaking engine coolant. Took it to the repair shop. Come to find out Ford in their infinite wisdom has place a coolant line that runs underneath the intake manifold. It is called a Coolant Bypass Line. Needless to say it cost 450.00 to repair including parts and labor. Per the mechanic Ford has a repair kit that you can buy but has not issued a recall even though it is a known problem.

Good luck I have read you can do it on your own but is a pain in the but.

A stuck open thermostat will not allow the coolant to get up to proper temp, thus poor heat from heater. A stuck closed thermostat will not let coolant circulate and will cause the engine to overheat.

If the temp gauge reads normal and the engine is not overheating, the thermostat is doing its job. The thermostat maintains the coolant temp by opening and closing allowing the coolant to flow or not to flow. When it is closed the coolant doesn't circulate.
