ACDelco Heater Cores

  • Lightweight aluminum tubes, air centers and tanks
  • Long-life alloys for corrosion resistance

There are signs the heater core in your vehicle may need to be inspected or replaced. They include:

  • An absence of or noticeably reduced heat blowing through the vents
  • A sweet odor inside the vehicle, sort of like maple syrup
  • A fine, slightly oily mist that appears on the windshield when the defroster is on
  • A damp spot on the floor, typically under the dashboard
