I'm sure thre is a reason against running the fan on high all the time the car is on...otherwise GM would have done it. I can't think of what that reason might be...but the operating temp for your car is about 180-220 anyway. If you have the auto climate control you can put it on auto which will kick your fans on low.

I really don't think you need high speed all of the time. Truthfully I don't think you need either, but that is another whole day of discussions...

If you must, I would start with the low speed fan. It should do a fine job of cooling the engine down.

if he had the fans on high and the 180 t-stat while going down the highway wouldnt the engine almost run too cool? therefore making the mixture richer, therefore killing his gas mileage, therefore causing him to lose money.therefore.


i like saying "therefore"

The lowest it should get is 180 degrees because the valve closes to the radiator.

I think it would be a better idea to run the fan in low speed now. But I would still like it to come on when I turn on the key. I hate the fact that the fan doesn't kick on until 210 or so. With the fan doing this there almost no point to having the 180 t-stat. I would directly wire it to a swich in the car but I would be afraid that I would forget to turn it on and over heat the car.

Does anyone know the steps to wiring my fan to come on with the ignition. fuddyduddy121 said about grounding wire at the relays. Is that all I have to do is ground the wire for the low speed relay and the fan will come on when I turn the car on??

You got it. Ground the wire. Don't lose the wire back to the computer in case you want to go back to the original configuration. Make sure the fans turn off when the ignition is off.

OK, that sounds simple enough, Thanks So Much for all your help!!!! I'll

Ok I grounded the wire and everything worked great.My fan comes on as soon as I turn the key. My Bonny is now running no hotter than 190 when idle ,while driving I still get 180 to 185. Works perfect. Thanks guys!!

You may have to switch that back for the winter. Put a switch on that wire for seasons.
