Hello,

The thermostat is located on the top of the engine.
If you follow the upper radiator hose (large diameter hose) to the engine, it is located inside that housing mounted with 2 bolts.

The thermostat on your vehicle is rated at 195F.

I have attached the thermostat replacement procedure for your vehicle.

Please let me know of any questions.

Thank you.
