Fan settings series 1
 

Hey guys, i am going to a 180 stat and would like my fans to be adjusted accordingly for this. Is there any way to do this?

No. Wire a fan override switch. You should see instructions from me in two or three different topics.

I've recently rewired the Zilla's override so the wire doesn't even leave the passenger cabin. You can go straight to the PCM. You simply switch a ground wire and the high-speed fans come on.

So then the setting are writen in stone in the computer huh?

Correct. But if you want your high speed fans to come on, simply set your ECC to AUTO. Both high speed fans will come on, assuming the ECT sees the car is up to operating temperature.

Bill,

I found your post entitled Last project.....More cooling.....

I seen the relay or whatever that you are talking about for the high speed fan, now I what, follow that wire into the car and put an inline switch?

No, you splice on a new wire to that one, (forget the low-speed, do only the high-speed) and run the NEW wire into the car, through a switch to ground.

Ohhhhh, ok ok ok, I see, cool, thanks for the info..... 8)

The fan relays always have a 12V supply to them. The PCM just applies a ground to the relay, and the fans come on. ;)

Gotcha, thats awesome info!

The fans in my Reatta were programmed by Ryan of GMtuners to come on sooner. With the 180 stat, I rarely get about 190 degrees.
