  • Designed for the original gasket and coolant path

🔌 Function

Circulates freshwater coolant through the engine and heat exchanger.

⚠️ Common Signs of Failure

  • Coolant leakage from the weep hole or seal
  • Bearing rumble or shaft play
  • Reduced heater or coolant circulation
  • Pulley wobble or belt-tracking problems

🛠️ Service Notes

  • Confirm the exact D2 pump variant against the engine's serial before ordering — this circulation-pump range spans units from just over 1 kg up to nearly 5 kg, and a generic "circulation pump" description does not distinguish them
  • Check the drive belt tension and thermostat before condemning the pump, and flush the system and fit fresh coolant when it is renewed
