FAQ

Q1: How can I confirm this water pump fits my specific excavator model?
A: This water pump is designed for Mitsubishi 6D14 and 6D15 engines. To confirm fitment, check your engine’s model plate or compare your existing part number with our OEM references ME787131 or ME996794. We recommend verifying with your machine’s service manual or contacting our technical support with your equipment details.

Q2: What is the recommended installation procedure for this water pump?
A: Installation should be performed by a qualified mechanic. Key steps include draining the coolant, removing the old pump, cleaning the mounting surface, applying a new gasket (not included), and torquing the bolts to manufacturer specifications. Always replace the coolant and check for leaks after installation. Refer to the engine service manual for exact torque values.

Q3: What maintenance is required to extend the life of this water pump?
A: Regularly inspect the cooling system for leaks, maintain the correct coolant mixture (typically 50/50 water to antifreeze), and replace the coolant per the engine manufacturer’s schedule. Ensure the drive belt is properly tensioned and the fan is balanced to prevent excessive vibration on the pump bearing. Avoid running the engine with low coolant levels.
