Q&A

To replace a " viscous coupling fan" with an electric fan you will have to find a place to mount a thermoswitch I would look for a thermoswitch that would mount in a coolant hose as opposed to the thermoswitchs that just push into the fins of the radiator core.There are companies that supply an adjustable rheostat switch that allows you to set the temperature the fan comes in at. Research to see what the largest fan you can fit that has the most air flow through the radiator and wire a mechanical over ride switch in for good measure.
