The existing water pump impeller can slip on the pump shaft on certain C7.1 Industrial Engines. If the existing water pump fails the impeller will slip on the pump shaft and not provide sufficient coolant flow around the engine. This letter does not cover pumps that have failed due to coolant or oil leaks. |
