Your GMC dealership isn't the only place to find genuine or original equipment quality repair parts to fix your Sierra 1500 Classic. The vehicle in your driveway symbolizes the best in class compared to all the other cars, trucks, and SUVs these days.
The need to heat the interiors our vehicles came before our ability to cool them. The engine of your GMC Sierra 1500 Classic circulates liquid coolant throughout the block to absorb heat, and transfers it through heater hoses to the heater core so you can warm up the passenger compartment. This heater core is almost always installed on the passenger side of the firewall, and you can find a couple of hoses leading to it. Basically, your GMC Sierra 1500 Classic 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.
Don't let a broken Heater Core spell the end of your car, truck, or SUV, and don't gamble with its condition by installing anything but the highest quality replacement parts.
