Thermostat replacement?

Hello,

The thermostat for your Ranger is located inside the thermostat housing, which is on upper part of the engine.
The upper radiator hose will lead you right to it.

You should only work ion the engine when it is cold.

I have attached the thermostat replacement procedure (below).

Please let me know of any questions.

Thank you.
