Product Details

Global Parts 8231511 is a direct-fit replacement for vehicles that require the specified application match. Use this part when servicing a leaking, restricted, or inefficient heater core on compatible Audi models.

What This Part Helps Address

  • Weak or no cabin heat

  • Fogging or poor defrost performance
  • Coolant loss from a heater core leak
  • Restricted coolant flow through the HVAC heater circuit

Installation Notes and Tips

Confirm the vehicle year, model, and HVAC configuration before installation.
