Is anyone aware of a 350z Radiator Fan Switch that switches on at a lower temp than the OEM thermostat? Found one here for Honda, but nothing on the 350z.

I did some searching here (and elsewhere) and found some posts on independent fan controllers and DIYs but don't want to mess around with install and wiring. Just looking for something I could swap out with the OEM part like the Mishimoto above. Thanks!

 

GTM sells one which work in conjunction with SPAL radiators fans. It should work as a standalone unit if you can splice into the factory fan harness.

 

I had no idea that you could get one for the car.

If the fans come on, I doubt it has anything to do with when they come on. OP, are you overheating? Only at idle, or when moving? Maybe we can make this into a troubleshooting thread for ya.

 

Ultimately the issue is oil temp which pushes up coolant temps when on the track. If the fan kicked on sooner it should help with both a little. However I'm getting close to just getting an oil cooler and be done with it. Thus the reason I don't want to go through a lot of time or expense for this mod. I've got a racing radiator themostat on order and switching to water/water wetter in the meantime. Appreciate the feedback though from both of you!

 

You need an oil cooler for the track, especially with an HR. Fans comming on earlier really won't help at all. The car at speed actually pushes more air than the fans will.
