Electric Fans ~ Sensor Installation
I am thinking of putting electric cooling fans on my '70 BB. I've never installed any before and was wondering what you do about the temperature sensor placement? Where does it go?
Thanks!
Thanks!

Don't buy the cheapest kit you can find. I did and now have problems. First the temp sender on it quit working (was the type you slide in the radiator fins), then the relay quit working.
I'm sure a quality setup from Painless or someone would work much better,

I just pulled a "Quality" Painless setup off my car the temp sensor went bad after 1 season of driving, I also had problems with the relay. I wired my dual Flexalites with a toggle switch off of the alt to inside the car, now everything works when i need it.

Thanks!Only problem I'm running into now, that I didn't consider at first, is that the dual fans, my radio, my electric fuel pump, etc. etc. are over-taxing my stock alternator (42Amp, I think), the fans alone are like 30 or 40 amps. So, I'm upgrading to an 80Amp alt.
Good luck!

I also decided to bypass the temp sensor for my DeWitts aluminum/dual 11" spals kit. I wired each fan seperately to its own toggle switch because alot of the time you don't need both fans running. This helps reduce the load on the alternator too. good luck...
