Engine Water Pump ME993965 ME-993965 for Mitsubishi Fuso Canter / Rosa Bus 4M50 4M51 5.2L Diesel — OEM Replacement with Gasket

The Engine Water Pump with Genuine Mitsubishi OEM number ME993965 (also listed as ME-993965) is a verified OEM-grade direct replacement for a wide range of Mitsubishi Fuso commercial vehicles, including the Canter truck series and Rosa Bus. Manufactured to Mitsubishi's stringent OEM specifications, this water pump is a critical component of the engine cooling system, responsible for circulating coolant throughout the engine block and cylinder head to dissipate heat and maintain optimal operating temperatures.

If your water pump is failing, you may experience one or more of the following symptoms:

• Coolant Leakage: Visible coolant puddles under the vehicle — a worn seal or gasket allows coolant to escape from the pump
• Engine Overheating: Temperature gauge consistently rising above normal — the pump is not circulating coolant effectively
• Whining or Grinding Noise: Unusual sounds from the front of the engine — indicates worn bearings or impeller damage
• Steam from Engine Bay: Steam or vapour rising from the radiator area — indicates severe overheating
• Coolant Loss: Unexplained drop in coolant level with no visible external leaks

Our manufacturing and inspection processes ensure every water pump meets or exceeds Mitsubishi Fuso OEM standards.

Pre-Installation Checklist:

• Allow the engine to cool completely before starting work
• Drain the cooling system properly — coolant loss is inevitable, so be sure to have the correct coolant on hand
• Inspect the fan belt, pulley, and tensioner for wear — replace if necessary
• Clean the mounting surface thoroughly before installation
• Use new gaskets and seals during installation

Installation Guidelines (Reference Mitsubishi Fuso workshop manual):

1. Ensure the engine is completely cool and drain the cooling system
2. Disconnect the negative battery terminal
3. Remove the fan belt from the water pump pulley
4. Remove the fan and fan clutch assembly (if applicable)
5. Disconnect the coolant hoses from the water pump
6. Remove the mounting bolts securing the pump to the engine
7. Remove the old pump and clean the mounting surface thoroughly
8. CRITICAL: Install the new water pump with new gaskets and seals
9. Torque the mounting bolts to manufacturer's specified torque settings (refer to Mitsubishi Fuso workshop manual)
10. Reconnect all coolant hoses securely
11. Reinstall the fan, fan clutch, and fan belt
12. CRITICAL: Refill the cooling system with the correct coolant mixture and bleed air from the system
13. Start the engine and allow it to reach operating temperature
14. Check for coolant leaks and verify the cooling fan operates correctly

Maintenance Schedule:

• Inspection: Every 50,000 km / 12 months. Check for coolant leaks, overheating, or unusual noises
• Coolant Replacement: Every 2 years or 40,000 km — replace coolant to prevent internal corrosion
• Replacement: Recommended at 200,000 km or immediately if failure symptoms appear
• Note: The water pump is a critical wear item on commercial vehicles — proactive replacement is strongly recommended during major service intervals

Each water pump is securely packed in protective packaging to prevent shipping damage. Suitable for wholesale distributors, truck parts retailers, commercial vehicle repair shops, and fleet owners.
