FAQ
Q: How do I verify this water pump fits my Mitsubishi K3 engine?
Check the part number on your existing water pump. If it reads MM407405, 30H45-00210, or 30H45-00200, this unit is a direct replacement. Additionally, verify your engine model plate shows K3B, K3C, K3D, or K3E. For absolute certainty, provide your engine serial number and we can cross-reference with our OEM database.
Q: What is the recommended installation procedure?
Proper installation requires: (1) Draining coolant and removing the fan belt, (2) Cleaning the mounting surface thoroughly, (3) Applying a thin layer of gasket sealant to the new gasket (included with most pumps), (4) Torquing mounting bolts to manufacturer specifications (typically 20-25 Nm), (5) Refilling with appropriate coolant mixture and bleeding air from the system. Always replace the thermostat and coolant during water pump service for optimal system performance.
Q: What maintenance is required for this water pump?
This water pump features a sealed, maintenance-free bearing assembly. No periodic lubrication is needed. However, inspect the pump during routine coolant changes (every 2 years or 2,000 operating hours) for signs of leakage, bearing wear (unusual noise), or impeller corrosion. Always maintain proper coolant concentration with corrosion inhibitors to maximize pump service life.
