follow the top hose off the raddiator back to the engine block

there shoukd be a houseing with two or three screws it is under

here The thermostat on the 1994 and later 2.3L and 2.4L (Quad

4)engines is located above the radiator outlet pipe in the water

pump cover which can be reached from under the vehicle on the

passenger side. Note: The bolts are accessible from the top of the

engine between the no. 2 and 3 exhaust manifold runners. It may be

necessary to remove the engine to transaxle support brace to

facilitate removal of the radiator outlet pipe. On all other

engines the thermostat is located in the coolant outlet housing on

the cylinder head. Some 2.0L OHC and 2.5L OHV 4cylinder engines are

equipped with a drop-in style thermostat located in a stamped steel

housing mounted on the cylinder head. These models can be

identified by a large cap that seals the thermostat housing.
