please go to 5/29/03 and look at the question HIGH SPEED FAN??????. the time of the thread was 11:19 and there were 21 replys and i know you will find all you are looking for in the replys.that one question alone gets my vote as to the #1 question posted on this forum. by experience, replace the thermistat with a cooler one and buy the sensor for your fan with the copper tip. napa sold me one that was plastic and they dont work as well. bought mine cheaper and better at advanced auto parts. art
