My rad fan wouldn't come on until the temp hit 230. Why the factory set the car up this way I have no idea. Why the thermal switch goes into the computer and not the fan relay I also have no idea, but I didn't feel like reprogramming the computer, so I got a $27 Flexalite adjustable thermal fan switch from Summit. Came today and took an hour to put in.

Job is easy as can be. Run an "always on" power source to the switch and cut into the light blue wire to use the factory fan relay. Put the probe in the bottom of the rad (in the fins, not the water passage). Turn on the car, set the switch to have the fan come on at 200 degrees (5 degrees after the thermostat opens) and JOB DONE.

Works perfectly. Now I can sit in traffic all day long, if I have to and the temp never oes above 200.

Everyone should do this $27, 1 hour fix. You'll never worry about your climbing temp gauge in traffic again.
