Hello,

Just follow the upper radiator hose, you will see where it connected to the engine there is a housing where both of the hose connects to. The thermostat is inside that housing.
Replacing the thermostat is fairly a straight forward process for his vehicle.
All you will need are simple hand tools to complete this task.

Always work on the cooling system when the engine is cold.
It is a good idea to drain the coolant before getting started to reduce coolant spilling all over.

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
