FAQ

Q: How can I confirm this water pump fits my specific engine?
A: Verify your engine model matches NHA220. Additionally, compare the pump’s mounting bolt pattern, inlet/outlet hose diameters, and overall dimensions with your existing pump. If possible, provide your engine serial number and equipment make/model for cross-reference assistance.

Q: What maintenance is recommended after installing this water pump?
A: After installation, check coolant levels and bleed air from the cooling system. Inspect for leaks at the pump gasket and hose connections during the first few hours of operation. Replace coolant according to your engine manufacturer’s schedule to prevent corrosion and maintain proper lubrication of the pump seal.

Q: Is this water pump a genuine Komatsu OEM part or an aftermarket replacement?
A: This is a high-quality aftermarket replacement part manufactured by, not a genuine Komatsu OEM part. It is designed to meet or exceed OEM specifications for fit, form, and function. We recommend verifying compatibility with your specific application before purchase.
