Not only does your GMC have 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 the hot engine coolant runs through it. The biggest difference, however, is that a fan blows air over the core so the radiant heat enters your GMC passenger compartment. After it's used for hot air, the coolant returns to the engine for use elsewhere.
