Please explain how this works. All a thermostat determines the lowest temperature the engine will run. The engine will get hotter than that depending on circumstances.
You can have a 160 and the engine might still overheat.

There is an orange wire going from the four prong fan plug to the blower relay. I got that one covered.
There is another orange 52 wire coming from the climate control switch going into a connector. The wire is about four inches long. That's the one...
I made one many years ago by using 4 1/4-20 x 2" bolts, running a nut down part way, putting it thru the carb mounting holes and hand tightening another nut on top.
When you have no money you just make do.
