Where is the thermostat in a 1998 Cadillac Catera located?

In a 1998 Cadillac Catera, the thermostat is located in the engine compartment, specifically at the front of the engine, near the water pump. To access it, you typically need to remove the upper radiator hose and the thermostat housing. This placement allows it to regulate the coolant flow as necessary for engine temperature control. Always refer to a service manual for detailed instructions if you plan to inspect or replace it.
