ACDelco Heater Cores

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

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
Service Tip: If you are experiencing unexplained or reoccurring heater core leaks, or notice dark spots on your failed heater core, test your coolant for Electrolysis. If detected, correct the source of the problem before replacing your failed heater core to prevent repeat failure.
Cooling System Maintenance | Tips & Tools

Premature Heater Core failure is often caused by poor Cooling System maintenance. Protect your engine and maximize system performance with simple preventative maintenance:

  • Completely drain and flush the system using Cooling System Flush. Flushing the system is critical to prevent system contamination and failure.
  • Consider replacing the Heater Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. Rust and debris from degrading parts can clog the Heater Core and Radiator, and lead to costly engine damage.
  • Refill Radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
