What Is a Coolant Hose?
The coolant hose is a critical part of the automotive engine. Because an internal combustion engine runs so hot, a fluid called coolant is needed to circulate throughout the engine. The coolant basically picks up and carries the heat with it into the radiator, where cooler outside air dissipates the heat. The hose is therefore needed in larger sizes to carry coolant into and out of the radiator, as well as in smaller sizes along the intake manifold.
