I am trying to change the thermostat on the truck listed above 1500 SLT, with a 5.7 hemi. However, I do not know where the thermostat is located. Can you please tell me where it is located or tell me about a website with a picture so I can see? Thank you for your time!

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:

I have attached diagrams of replacement procedure for your reference.

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