Where is the thermostat located on a 1990 Ford Tempo?

MECHANIC TOLD ME IT IS LOCATED UNDER THE TOP HOSE TO THE LEFT OF THE TOP OF ENGINE......NARROW HOSE COMING FROM RADIATOR.....STANDING IN FRONT OF OPEN ENGINE COMPARTMENT.....IT WILL BE @ ABOUT THE 2PM POSITION.....HOSE ONLY ABOUT 1- 1 1/2 INCHES WIDE. On the right side of the motor, mounted to the drivers side of the motor between the motor and a hose. Its smaller than you would expect.
