Stop Overpaying at the Dealer: OEM-Quality Cooling for Your 3D72

Owning a classic Komatsu mini excavator like the PC10-7 or PC12UU-2 means you know the value of hard work and a tight budget. When your 3D72 engine starts overheating, the last thing you need is a massive bill from the local dealership. Our 119660-42004 Aftermarket Water Pump delivers the exact same cooling performance and reliability as the original part, but at a fraction of the cost. Keep your engine running cool and keep your hard-earned money in your pocket.
