Thermo Fan switch

[Wrath]

Sup guys,

just a quick question, im installing a 16" thermo fan in my R33 and im just trying to find which temp sender does what.....

from my understanding the 2 on the water outlet are for the ECU and the temp gauge, now is the one on the bottom of the radiator a temp switch?????

Yes. On 32s, it operates the A/C fan (the small one out front) in an over-temperature situation when using AirCon. It switches a relay in the block immediately rearward of the battery - you can hook in there to switch another relay to operate the fan.

Frankly, I'm not in favour of thermo fans on Skylines. I tried it, and I was continually having the engine overheating, even in the lightest of workouts. For the couple of kW gain, I don't believe it's worth the risk to the engine.

yeah i assumed it was a switch i just wanted to double check....

the main reason im going for the thermo fan isn't really for power... im making up my intercooler pipe and i wanted to remove the fan so i have more room and it makes the engine bay a tiny bit cleaner..
