Question about 2001 Ford Windstar
The best thing to do is to buy a Haynes or Chilton manual for your vehicle.
Purchase the replacement thermostat and gasket (no they do not come as a set.)
Items needed: socket and ratchet, a tube of liquid gasket, a wire brush, screwdriver for hose clamp
Open the hood, disconnect the Neg terminal of the battery (not the red one)
The radiator accept hot water at the top and feeds it to the water pump on the bottom.
Most thermostats are located on the engine block at the other end of the water hose going to the top of the radiator.
Trace it back, and remove the hose clamp.
Pull the hose clamp back (you do not need to take it off)
Pull the hose off the thermostat hosing neck.
The housing will be held on by 2 or 3 bolts, remove the bolts to remove the housing
BEWARE OF THE ORIENTATION OF THE .THERMOSTAT
The thermostat should come loose.
There will be gasket material stuck to the housing and the engine block, it must be scraped off before installing the new gasket.
Compare old thermostat with new one. Make sure they match.
A good tip is to stress the new thermostat in boiling water to insure it works. Boils some water, and place the thermostat in the water and watch it open. pour out the water, run it under cold water to cool it off.
After using a wire brush to remove the old gasket material,
place liquid gasket along the edge of the engine block opening and place the new gasket on the opening.'
Place the new thermostat in place (IT MUST GO IN ONE WAY)
Place the housing back on the engine block and replace the bolts, (tighten the bolts gradually )
replace the hose on the neck, and replace the clamp and tighten.
remove all tools and reconnect the battery
Good luck and don't forget to vote.
