1997 Cummins 8.3 running hot, The motor is in a garbage
The motor is in a garbage truck. It normally runs at about 195-200. The last week or two it starts to climb over 220. If you are driving from stop to stop for several hrs it stays around normal. But if you start to drive farther distance it starts to go up. When we go to the landfill it will get real close to the red line and if you let off the throttle to idle it will drop down but not to 200. We have replaced the coolant sensor and that didnt fix it. It is the original radiator. The coolant has been changed with the coolant filter since the truck was new. My mechanic thinks I need a new radiator. The fins are clean so there is no dirt or bugs obstructing air flow … read more
