Common Replacement Reasons

  • Restricted coolant flow in the HVAC heating circuit
  • Incorrect hose fitment after prior repair work
  • Loss of heater performance caused by hose leakage

Installation Notes

Verify the OE number 64 21 6 923 944 and compare the hose routing, length, and connection points before installation. Confirm the vehicle uses the Water Pump To Valve configuration shown in the fitment list. Inspect adjoining coolant components and clamps during service, and replace any worn sealing surfaces before refilling and bleeding the cooling system.
