Weichai WP4 ENGINE Water Pump Assembly 1001762507
This water pump is primarily responsible for driving the circulation of engine coolant (antifreeze) and is a critical wear part essential for maintaining the engine's normal operating temperature.
Common Faults and Troubleshooting
1. Water pump leakage (water seal wear): Green or red antifreeze crystals or drips appear at the drain hole beneath the water pump or at the base of the pulley, accompanied by accelerated antifreeze consumption. Severe coolant loss can cause the engine to overheat and boil over, potentially leading to a blown cylinder head gasket or cylinder scoring.
2. Bearing play and abnormal noise (due to excessive belt tension or end of service life): A continuous metallic friction noise emanates from the front of the engine. Manually shaking the water pump pulley reveals noticeable looseness or play. If the bearing seizes, the 8PK engine belt may snap instantly, causing the alternator, cooling fan, and air conditioning system to stop functioning.
Complete Set of OEM Assembly Components
1. 1001762509: Water pump gasket (paper/rubber composite; a critical single-use consumable that must be replaced upon disassembly to prevent joint leakage).
2. 1000083406: Fan clutch (typically serves as a drive component extending from the front of the water pump).
3. 1004119437: EGR cooler assembly (high-pressure coolant discharged from the water pump is routed primarily to this cooler).
4. 90011420036: Hex flange bolt (used to secure the water pump housing to the engine block).
