How to Change the Thermostat in a Ford Taurus. If you've noticed lately that the heater isn't blowing warm air in your Ford Taurus, you might be ready for a thermostat change. Fortunately, all you'll need to change the thermostat in a Ford Taurus is a couple of tools and about a half hour or so, and you'll soon be back on the road.

Turn the drain valve at the bottom of the radiator counterclockwise to drain the coolant from your Ford Taurus into a suitable container. Depending on the size of the container, it may be necessary to lift the front end of your Taurus with a jack and lower it onto jack stands, or use wheel ramps.

Follow the upper radiator hose to the point where it meets the thermostat housing at the front of the intake manifold. Loosen the hose clamp and pull the radiator hose off the water connection on the thermostat housing.

Take out the two bolts on the thermostat housing cover with a 13mm socket or wrench and remove the cover. Clean any old gasket residue from the inside of the thermostat housing cover. Pull out the old thermostat.

Insert the new thermostat into the thermostat housing with the spring-side facing into the engine. Install the new thermostat gasket. Use a spray adhesive to hold the gasket in place, if desired.

Reinstall the thermostat housing cover. Tighten the bolts to 89-124 in. lbs. Reattach the upper radiator hose to the thermostat housing. Make sure the drain valve on the radiator is closed.

Fill the radiator with new or reserve coolant. Start your Ford Taurus and allow it to warm up to its normal operating temperature. Check hoses and connections for leaks and tighten hose clamps to stop any leaks, if necessary. Add more coolant as needed.

Warnings

Don't drain the coolant from your Ford Taurus while the engine is hot.
