Engine temperatures cummins 350
New to us 2001 holiday rambler imperial. Engine temp us running about 180-200, higher going up hills, is this normal range?
Forum Discussion
180 is low. The range should be in the 195 to 200 range and those numbers will climb as you head up the hill. Is this a side radiator? If so the hill climb temp should peak out around 210 and then the fan controller will come into play and reduce the temps. If a rear radiator, then you will have to raise engine RPM to increase air flow over the radiator and turn the water pump faster.
