All Delphi heater cored are aluminum construction with high-strength brazed joints to create a durable and long-life product.

Delphi heater cores carry hot engine coolant through their internal tubes while the fan blower pushes warm air into the passenger compartment. Heater cores not only keep passengers warm but are also responsible for defogging/de-icing the windows.
