A blocked heater hose could cause a leak. A stopped up heater core could as well. Or the connector in the Windstar could be cracked.
my 2001 ford windstar is still overheating even though i changed out the thermostat. what could it be?
Have you replaced the thermostat?
Personally , if I want an engine cooling thermostat changed I just take it in and let a mechanic / technician do it and pay the bill
water pump. thermostat.
a new heater core
Not very likely - the Windstar was significantly redesigned in 1999, and the dimensions of the vehicle were changed.
If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
have you changed the battery in the thermostat?
Sounds like thermostat is not opening and needs replacing
Check the Blender door... Also check the temp knobs they make be broken.
How did you change the thermostat?
It could be you thermostat Have you have already checked oil level, and/ot changed oil recently Exaust restrictions can cause overheating
