What It Helps Address

  • Weak or uneven rear cabin heat
  • Coolant odor from a leaking heater core
  • Fogging caused by poor HVAC heat performance
  • Restricted heat transfer from a corroded or damaged core
  • Rear HVAC temperature complaints in Porsche Cayenne, Volkswagen Touareg, and Audi Q7 models

Installation Notes and Tips

Verify rear HVAC fitment by model year and note the listed dimensions before installation. Inspect coolant hoses, seals, and the HVAC housing for contamination or corrosion during replacement. Proper bleeding of the cooling system is important after heater core service to restore normal heat output.

Quality Assurance
