Check For Interference Between Water Temperature Regulator And Cylinder Head Bore
Usage:
3306 Truck Engines
Reports indicate that some 3306 Truck Engines with 7N208 Water Temperature Regulators have experienced overcooling or cooling system pressure surges. In many cases this problem is caused by interference between the water temperature regulator guide tabs and the bore in the cylinder head. Interference occurs when the guide tabs are bent outward. When the guide tabs are bent slightly inward, there is no chance of the interference between the tabs and the cylinder head.
