Troubleshooting

Coolant leak from the water pump area

Check the mounting bolts for proper torque and ensure the gasket is correctly seated and in good condition. A new gasket is typically included or should be replaced with the pump.

Engine overheating after installation

Verify the cooling system has been properly bled to remove all air pockets. Ensure the correct type and amount of coolant have been used. Check that the drive belt for the pulley is properly tensioned and not slipping.

Unusual noises (whining or grinding) from the pump

This may indicate a worn bearing within the pump. The pump should be inspected and likely replaced.

Setup, Compatibility & Care

Compatibility: This Quinton Hazell Water Pump (QCP3700) is exclusively designed for:

  • Vehicle: MERCEDES-BENZ S-CLASS (W220, V220)
  • Model: S 320 CDI (220.026, 220.126) Saloon
  • Engine: OM613.960
  • Manufacture Date: August 1999 to September 2002

Setup: Installation requires draining the engine coolant, removing the old water pump, and fitting the new unit with a new gasket. It is strongly recommended that this part be installed by a qualified mechanic to ensure correct fitting and to prevent coolant leaks or engine damage. Proper torque specifications for mounting bolts must be followed.

Care: Regular checks of the coolant level and the condition of hoses and belts connected to the water pump pulley are advised. No direct maintenance is required for the water pump itself, as its operation is internal. However, ensuring the cooling system is clean and free of debris will prolong its life.
