Where is the thermostat located on your 1998 Chrysler Cirrus LXI model with a 2.5L V6 engine?

The thermostat on a 1998 Chrysler Cirrus LXI with a 2.5L V6 engine is located on the engine block, at the lower end of the engine's water jacket. It's generally a relatively low profile housing, and you'll likely need to look carefully beneath the intake manifold, near the water pump. Accessing it usually requires some work, potentially involving removing various components for better visibility. A repair manual specific to your vehicle year and engine will provide detailed diagrams and instructions. Be prepared for coolant to drain when replacing it.
