The function and purpose of Heater Hose.

The need to heat the interiors our vehicles came before our ability to cool them. The engine of your GMC Sierra 2500 HD 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. GMC Sierra 2500 HD heater hoses help cool the engine by supplying an alternative path for hot coolant to travel. The return heater hose re-introduces the coolant to the engine after it has heated the heater core so the radiator can return it to optimum temperature.
