Re: Engine Fan Speed Reply #25 – August 11, 2015, 06:51:45 pm Quote from: Dave M – August 11, 2015, 04:25:05 pmWith new radiator from FOT, rebuilt fan motors, ISM500, worked great on I 26 in NE NC, ran mountain 65 mph up & over, temp never went above 194. Would appear clean radiator, proper fan condition sure handled the 500 hp, no problem running 1540 torque and 480 hp most of way up.Am delighted with the results.Engine ran little warmer down hill, 5th gear 2nd or 3rd notch retarder, kept retarder temp under 250. Love that torque..!!! Im sure you we're smoking all those semi's up the grade. Quote Selected 1 Likes

It is the elevation. The thin air at 10,000 to 12,000 feet will not remove as much heat at the heavier air at 5,000 feet.Definite point. Quote Selected

Re: Engine Fan Speed Reply #28 – August 13, 2015, 01:03:22 am Yeah with heavy toad and 42' tag axle nobody keeps up, unless I back out intentionally just to not run at WOT unnecessarily. I have followed trucks up the hill at 1/4 throttle many many times. Quote Selected 1 Likes
