Pulley Diameters

I drove my car on Saturday for an hour around 11am--95*+ outside temps. Approximately 45 miles total including 32 miles on the freeway @ 60-65 MPH. It very slowly moved up to 210*....Awesome!! Then the last few miles the temp gauge climbed again to 230* :BangHead:

Shut off the AC & kept driving until the temp lowered--which it did.
