Crispy2k10 Posted May 24, 2017 Share Posted May 24, 2017 I have a 1992 Mack cab over truck with an E7 motor. It is used in a feed mixer to feed dairy cows daily. This truck runs hot, 200-215 on a 65 degree day. The fan is an air over electric I believe, and only blows are out the front of the truck, there is a button to change the fins so that it will pull air in but it only works for maybe 5 seconds when u push it. The fan also sits back about 2 feet from the radiator. Does anyone have any suggestions on what I should check to get this thing running cooler? We had a 80 degree day here in NY a while back and the truck wouldnt cool below 205 unless it idled for 40 minutes. Quote Link to comment Share on other sites More sharing options...
