Fan temp settings for late model C4?
Anyone know what the settins are for the electric radiator fans on a 96? My wife's first fan is coming on at about 220 deg F. Turn on the A/C and the fans come on as expected. This seems high to me. I replaced both primary and secondary fan relays and they still come on this high.... :confused:

Thats close, and yup I think it is too hot also. You can have the fan on and off temps changed by reprogramming the
chip, also change the thermostat to a 160 or 180 and that should help.

I have an 84 and that is about right. I thought mine was a bit high as well so I changed the fan switch to a 95c degree unit. Now the fan will comes on about 208 and runs much cooler. The optimal temp. for a small block is around 200 degrees.

220 is the right temperature. Now I am sure we can start a debate that has been had here many times whether this is too high or not.
There is merit to both sides, I'll stick with what the factory did.
