Re: Electric fan thermostatic switch location; radiator or intake?

Quote:
I too have spent a great deal of money on my stroker engine. I want to make sure it is cooled properly. My radiator is a custom aluminum build from Wizard Cooling. I have dual SPAL fans set up in it with a single thermostatic switch in the radiator. I'm just not sure the switch is properly located.
There is more than one way to skin a cat...it looks like the bung in the radiator is near the top which would be the hot side. You should be fine putting the switch there. When the thermostat opens and water circulates, this section of the radiator should be near the temperature at the thermostat. Depending on the efficiency of the radiator, though, it could be lower than the temperature of the water in the engine...might be splitting hairs at this point, though.
