Installation Notes and Tips

Verify the core dimensions against the removed unit before installation, especially on Audi A6, A6 Quattro, and 100-series vehicles where production changes can affect HVAC components. Inspect hoses, clamps, and surrounding HVAC case components during service so the new heater core is not installed into a system with unresolved leaks or restrictions. Confirm the vehicle identification number and application notes, including the 1998 A6 and A6 Quattro cutoff to VIN 4A-W-005 000, before ordering.
