Without going into too much detail, you'd need the PWM module from a Corvette to make it work and be able to set, or have somebody set, the computer to work it.
that's pretty wild I did not know that. Only corvettes get that?

That's all I know about, for sure. I can say for certain that G8s, GTOs and new Camaros don't have it, though. Based on what's available in HPTuners, I'd guess it could be made to work with any of those computers, but I've never tried it.

It's been working great on the Camaro for the last 3 years and 15k+ for me. With the big Ron Davis and dual Spals, you rarely hear the fans run, since they're almost never at 100%.

I have a DCC in my car and even with one of the fan motors having a bad bearing I still don't hear them. At idle on a 90* day they hover around 6-7 volts. I had no idea GM was using PWM.

Any reason the fan controller from Dakota Digital would not work?

Ok, in tying up some loose ends, I decided to just use the sending unit that came with the Dakota Digital and install the sensor in the radiator line.

Do I install it in the large 1.5" line or the smaller 1.25" line? I almost pulled the plug on a 38mm adapter (1.5"), but then remembered that I don't know which line I have to install it in!


Here's a decently priced one for $25.

I guess I should clarify...should it be the upper or lower radiator hose?

the upper hose is water returning from the engine to the radiator and would be the one to use.

That's what I thought. Thanks Jody.
