Yuchai water pump 6QAJ-1307010D for cooling-system service
This product record identifies water pump 6QAJ-1307010D. The pump circulates coolant through the engine cooling circuit; the correct replacement must match the engine version and its physical interfaces. Confirm the complete engine model and serial before ordering.
Verify the pump and drive configuration
Compare the number 6QAJ-1307010D with the removed pump and catalog reference.
Check housing shape, mounting-hole pattern and coolant-port positions.
Compare shaft, hub or pulley arrangement with the original assembly.
Confirm the supplied pump's contents; gasket, seals and hardware are not specified in this record.
Inspect related cooling components
Before fitting a replacement, inspect the mating surface, hoses, clamps and coolant condition. Coolant leakage, noise or temperature changes can have other causes, so diagnose the system rather than assuming the pump is the only fault.
Installation and commissioning
Use the specified gasket or seal and tightening procedure for the confirmed engine. Refill and bleed coolant according to service instructions, check for leaks, and monitor system behavior after startup. Never open a hot pressurized cooling system.
