Hello,

If you follow the upper radiator hose from the radiator to the engine. The thermostat is located inside the housing where the hose goes into the engine.

It is important to only work on the cooling system when the engine is cool.

Here is a helpful guide:

Please let me know if you have any questions.
Thank you.
