EFI Cold Case rad/fans
 

Hello all, my 67 GTO non air is almost out of body shop prison, my Pro Flo 4 controls my rad fans on my Kaufman 461. Just looking for ideas on fan on/off set points. I'm using a 195 stat

Thanks

I use a 180 degree stat, but the engine pretty much always runs at 194. I have mine set to turn on at 197 and turn off at 195. I've found that setup for me works well with keeping the fan off at cruising speed where it's not needed.

With a 195 thermostat I'd like to turn the fans on around 203 and turn them off around 196 or 197. But every car will behave differently and there will be a bit of trial and error that you'll need to do to find what your car likes.

The electric fans did not work for me, I went back to the clutch fan and the stock shroud, that pulls more air and keeps the 571 cu cool in the Az heat. I run a 160 thermostat personally I like to keep it cool. Just driving around town it runs 166 to 173 on the highway its a little warmer when its 90 outside.

This is my recommendation as well.
