Anyone who owns a GMC knows that when it comes to repairing their car, truck, or SUV only the highest quality replacement parts will do. It's not a regular occurrence that you realize that you have to buy a replacement Heater Core to repair your automobile. You bought your K15 because its reliability and trusted quality struck a chord inside you; so why would you be okay with second rate when it comes to superior quality auto parts? Make no mistake, you didn't buy your K15 unless you understood you would be getting performance and great value both rolled up into one car, truck, or SUV.
The need to heat the interiors our vehicles came before our ability to cool them. The engine of your GMC K15 constantly pumps and turns a mixture of water and ethylene glycol through the engine block in order to absorb the heat it generates, and sends this liquid to the heater core (a small radiator) through a heater supply hose when you want to warm your vehicle's cabin. If you've ever wondered why there are two hoses leading to the passenger side of your firewall, that's where the heater core is located. To make a long story short, your GMC K15 heater core is a small radiator that creates a pocket of heat for your blower motor to funnel air past as it goes through to the interior.
