The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles these days. When your GMC K35 left the factory, it was destined for a person with discerning taste who wants longevity in their automobile. It's not every day that you realize that you have to buy a replacement Heater Core to fix your car or truck. GMC automobile drivers have come to expect a certain level of reliability when driving their K35 around town.
Believe it or not, your car or truck's heating system is closely tied to its engine cooling system. The engine of your GMC K35 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. 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. To make a long story short, your GMC K35 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 bring about the demise of your car, truck, or SUV, and don't risk lowering its resale value by using anything but the best replacement parts.
