Where is the thermostat located on my Dodge Truck and is it easy to change?

Hello,

Locating the thermostat is simple, just follow the upper radiator hose from the radiator to the engine. The thermostat is located inside the housing, where the hose attaches with a clamp.
Simply remove the housing to access the thermostat.

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

I have attached diagrams of replacement procedure for your reference.

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