#1: What activates the radiator fan? Author: razza987, Location: NorfolkPosted: Tue Mar 17, 2015 4:11 pm ---- I've removed the standard rad, fan and cowling from the race car. I'm replacing the rad with a Golf GTi one and an aftermarket fan. The standard rad doesn't have a thermo switch fitted, so what sensor/switch activates the fan?
Cheers,
Raz

As I have an Emerald ECU, I guess the fan temp must be controlled by that

I've got mine controlled by the Omex ECU and I can control the on and off temperatures.
