2007 KW with ISX runs hot
Over the last few weeks I've noticed my water temp running about 10 degrees hotter than normal. It usually stays between 180 and 190, now it's staying between 190 and 200 thus the slightest pull or anytime I have to get into the throttle the fan kicks on. I've replaced the radiator less than a year ago. Also I've have to add a gallon of antifreeze every two or three weeks, but it does have a small leak close to the egr. I haven't any real mpg loss, still averaging 6.4 over the last month. I've been an O/O for the past 15 years and never had an issue with the fan on so much, any suggestions of where I should start looking ?
Is this a worthwhile discussion?
