A:BEST ANSWERHi Anita,
This is a thermostat with thermostat housing.
To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application.
To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

Damaged heater cores often go hand in hand with coolant problems.
Where Is the Thermostat Located?Have you driven your vehicle recently? Because if the answer’s yes, you’ll want to turn off the engine and let it cool down before trying to access the thermostat.
