Suppose a Heater Core malfunctions it can translate into a very annoying experience for almost anyone.

If you find yourself stranded and parts need to be replaced on your GMC, then we can help you. All GMC drivers will agree that only the most reliable Heater Core parts are the only ones that they will install on their automobile.
You know that your GMC has a large radiator near the front of your vehicle (behind the grille), but you also have another little one near the firewall. Your HVAC heater core behaves in the same way your radiator does, in that it is designed to have hot engine coolant passing through it. The biggest difference, however, is that a fan blows the radiant heat from the core into your GMC passenger compartment. The coolant then leaves the heater core and goes back to the engine for use elsewhere.
