MB3C –

Eastern Industries 18-1793 is an aftermarket engine water pump for compatible Cummins 8.3L C-Series diesel engines requiring a long-nose pump. It replaces the water pump identified by Cummins part number 3800975.

The pump circulates coolant through the engine cooling system to help maintain proper operating temperature. Its long-nose configuration is an important fitment detail: Cummins 8.3L engines use different water-pump arrangements, so the original pump number and hub configuration should be checked before ordering.
