GMC automobile owners have become used to a certain level of reliability when driving their Sierra 3500 HD around town. You bought your Sierra 3500 HD because its dependability and longevity struck a chord inside you; so why would you settle for second best when it comes to superior quality auto parts? Obviously, you didn't buy your Sierra 3500 HD unless you knew that you wanted performance and great value both impeccably combined into one car, truck, or SUV. It's not every day that you discover you need a replacement Heater Core to fix your vehicle.
The need to heat the interiors our vehicles came before our ability to cool them. The engine of your GMC Sierra 3500 HD constantly pumps and turns a mixture of water and ethylene glycol through the engine block in order to absorb the heat it generates, and transfers it through heater hoses to the heater core so you can warm up the passenger compartment. Your heater core sits inside a heater box, mounted behind your glove compartment, and you can find it by following the two heater hoses towards the passenger side of the firewall. Essentially, your GMC Sierra 3500 HD 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.
