3803403 | Cummins Pump - Water L10/M11/ISM

The Cummins L10/M11/ISM water pump is a critical component of the engine cooling system. It is responsible for circulating coolant throughout the engine to maintain optimal operating temperature.

The water pump is driven by the engine's accessory drive system and typically consists of a cast aluminum housing, impeller, and bearing assembly. The impeller is designed to move coolant through the engine block, cylinder head, and radiator to dissipate heat. The bearing assembly is designed to support the impeller shaft and prevent leaks.

The water pump is typically replaced as part of a regular maintenance schedule or when it begins to show signs of wear, such as leaks, noisy operation, or reduced coolant flow.
