Ford Taurus Has No Heat Q. Heater is barely working - possibly the thermostat? Is this something I would be able to fix myself? 1997 Ford Taurus Automatic transmission 70,000 miles Diane

A. If you mean by "barely working" that the outlet air temperature is too low, then yes, it could be a bad thermostat. They are not difficult to change and with the proper tools it takes about 30 to 45 minutes to do. Here's how:

REMOVAL:

1. Drain the engine cooling system so that the engine coolant level is below the water thermostat.
2. Disconnect the upper radiator hose from the water hose connection.
3. Remove the three water inlet connection retaining bolts Remove the water hose connection.
4. Remove the gasket and water thermostat from the water hose connection. Do not reuse gasket.

INSTALLATION:

1. Install the water thermostat, gasket and water hose connection as illustrated
2. Install and alternately tighten the retaining bolts. Tighten bolts to 89-124 inch lbs.
3. Connect the upper radiator hose to the water hose connection
4. Fill the cooling system with a 50/50 mixture of the proper anti-freeze and water.
5. Start the engine and check all hoses and connections for leaks. Allow the engine to warm up so that the water thermostat opens
6. Stop the engine. Top off the coolant overflow reservoir as required to maintain minimum cold fill level.

And that's all there is to it Diane! Let me know how you did.
