i know its done a really good job at keeping the car cool, with the clutch fan on the motor and the electric 18 inch fan mounted to the radiator she runs at close to 150 or lower most of the time except for limping it home today it hit 200 and that is the hottest the gauge has ever read since i have owned it. are you one of these people? beside her sat her homely husband. i have been using it for the past few days, and so far so good. let's wait a while and see how the temperature continue to change.
