Go back and read that Taurus fan upgrade thread. You can get the fan brand new from
www.rockauto.com for $90 and the wiring harness from
www.thoroco.com for $60 and your cooling and fan issues will be resolved.
I did this on my coupe and it works great. I drove from Phoenix to San Diego last weekend during the hottest part of the day averaging 85 MPH with the A/C running and it was 114 degrees outside. The car ran a steady 205 and even less when i was stuck in line at the border patrol check points.
