Information:
Overcooling
Possible Causes/Corrections Long Idle PeriodsWhen the engine is running with no load, only a small quantity of fuel is burnt and engine heat is removed too fast. Very Light LoadVery light loads, and a very slow speed or downhill travel can cause overcooling because of the low heat input of the engine. The installation of shutters helps to correct this condition. Defective Water Temperature RegulatorsA regulator that is "stuck" open (will not move to the closed position) will cause overcooling. A thermostat that is stuck between the open and closed positions, or only opens part of the way, can cause overcooling when the truck has a light load. Also, coolant leaks around the thermostat, such as vent lines, can cause overcooling. Shunt Line ConnectionThe shunt line may be connected in the wrong place (top hole on bypass housing). Refer to Installation Drawings, LEBT2480, for the proper connection point.
