Installation Notes and Tips

Verify the existing heater core dimensions and pipe layout before installation. Because pipes are not included, reuse or source the correct vehicle-specific connections as required by the application. Flush the cooling system and inspect hoses, clamps, and the HVAC case for contamination or leaks before installing the new core. Confirm fitment against the vehicle’s year, model, and HVAC configuration for Audi S6, Audi RS6, and related applications.
