How This Heater Core Works

This heater core transfers heat from engine coolant into the vehicle’s rear HVAC system so the cabin can receive warm air through the climate control unit.

This part cross-references Edelmann 92054 for the same application.

Common Problems It Can Address

• Rear cabin heat loss

• Restricted heat output from internal blockage
• Temperature imbalance in the rear HVAC system
• Replacement need after corrosion or age-related wear

Installation Notes and Tips

Verify rear-position fitment before installation and confirm the vehicle matches the listed year range and model. Because heater core service is tied to the cooling and HVAC systems, inspect coolant condition, hoses, and related seals during replacement. The adjustable pipe positioning attribute is not listed for this part, so confirm line routing against the original unit before assembly.
