Finding the thermostat - 1996 Mercury Sable

It would be rather nice to know WHICH ENGINE your sable is equipped with...ESPECIALLY if you are asking for the location of engine components.

3.0L DOHC (VIN code "S") The thermostat housing is located at the engine end of the LOWER radiator hose

3.0L OHV (VIN codes "1", "2", and "U") The thermostat housing is located at the engine end of the UPPER radiator hose.

NOTE: the "VIN code" is the engine identification code and is the 8th digit in your Vehicle Identification Number.

Just follow the upper radiator hose from the radiator to the engine, where is connects to the engine remove the hose and the cover under it to expose the T-Stat. Drain about 1/2 gallon of coolant out before you start work. Bleed the air from the cooling system (refer to service manual for this year and engine type) after the T-Stat is replaced to prevent poss overheating.
