FAQ
Q1: How can I confirm this water pump fits my Komatsu 6D140 engine? A: To confirm fitment, please check the part number cast into your existing water pump or listed in your engine’s service manual. The primary OEM number is 6212-61-1203. Ensure your engine model is a 6D140 variant. If your part number differs, please contact us with your engine serial number and original part number for cross-referencing.
Q2: What is the typical installation procedure for this water pump? A: Installation should be performed by a qualified mechanic following the engine manufacturer’s service manual. General steps include: draining the coolant, removing the fan and belts, unbolting the old water pump, cleaning the mounting surface, applying a new gasket, installing the new pump, and refilling the cooling system. Always replace the coolant and inspect the thermostat and hoses during this service for best results.
Q3: How do I maintain my new water pump to ensure a long service life? A: Regular maintenance of the entire cooling system is key. Use the correct type and mixture of coolant as specified by Komatsu (typically a long-life coolant mixed with distilled water). Regularly check the coolant level and condition, and inspect belts and hoses for wear. Ensure the radiator and cooling fins are clean and free of debris. A well-maintained cooling system significantly extends the life of the water pump and the engine.
