i've heard & read several (other) posts about people re-wiring their rad fans to engage on-demand at the flick of a switch but haven't quite found one that has had done what i'm looking for so please hear me out: is it possible to retain the rad fan relay feature, meaning the thermo switch/relay will still activate the fan when hot but still allow me to still override this and engage the fan manually..? i'd like this routed through an IGN-activated power feed so that i can't accidentally leave the fan engaged and drain my battery after the engine is off.
i ask because i've noticed that at times even though the engine is hot at about 94+ deg C, the rad fan only engages for about 5 to 10 seconds then goes back off for an extended period of time before kicking in again. in my understanding, i thought the thermo switch should remain open the whole time until the coolant temp drops below the threshold, which i suspect is 94C..?
can anyone shed some more light on this..?
