Description

The Cummins Water Pump 3286277 is a precision-engineered diesel engine cooling component designed to circulate coolant efficiently throughout the engine , maintaining proper operating temperature and preventing overheating in Cummins diesel engines. This water pump is a direct replacement for Cummins OEM part number 3804895 , making it ideal for engine rebuilds, cooling system repairs, and complete overhauls. Manufactured from high-strength cast and machined materials , the Cummins 3286277 water pump is built to withstand continuous coolant flow, pressure variations, vibration, and high-temperature operation common in heavy-duty diesel applications. The precision-balanced impeller ensures consistent coolant circulation, reduced cavitation, and long service life under demanding conditions. Designed for accurate fitment and OEM-spec coolant flow , this water pump plays a critical role in protecting the cylinder head, engine block, oil cooler, and other cooling system components from heat-related damage. Replacing the water pump during an engine overhaul is strongly recommended to ensure reliable cooling performance and prevent premature engine failure caused by coolant loss or restricted flow. This water pump is commonly used in Cummins diesel engine rebuild, overhaul, and cooling system service applications , including on-highway trucks, industrial engines, and heavy-duty equipment.
