Weichai Engine Water Pump 612600060307 – Fitment and Cooling Guide

Weichai water pump 612600060307 circulates coolant through the engine. The recorded part number is the primary identifier, but engine version, drive type and external interfaces should still be confirmed.

Ordering basis: Confirm part number 612600060307 and match the Weichai engine nameplate, drive arrangement, coolant ports and mounting face.

Water-pump details to verify

• Photograph the Weichai engine nameplate and pump markings.

• Compare mounting holes, pilot and gasket profile.

• Confirm pulley, gear or hub interface and rotation.

• Check coolant inlet and outlet positions.

Diagnose overheating before replacement

Overheating can also come from a blocked radiator, thermostat, fan, belt, coolant loss, air pockets or head-gasket problems. Pump leakage, bearing play or poor circulation should be verified before removal.

Cooling-system installation checks

Drain coolant safely, clean the mounting face and prevent old gasket material from entering the system. Install the specified gasket, align the drive, refill with approved coolant and bleed air according to the engine procedure. Check leakage and temperature after warm-up.

FAQ

Is part number 612600060307 enough to order?
It is strong evidence, but the Weichai engine model, serial number and drive interfaces should still be checked.

Does coolant leakage always mean the pump is faulty?
No. Inspect hoses, joints, housing and nearby seals to locate the source.

Why must air be bled after installation?
Trapped air can reduce circulation, cause hot spots and create misleading temperature symptoms.

Compatibility note: Confirm the Weichai engine identity and all pump interfaces before final selection.
