What Vehicle Hoses Do
The vehicle’s hoses are the cooling system’s most vulnerable structural component made of flexible rubber composites that handle vibrations from the engine. Hoses are designed to withstand coolant under intense pressure, extreme temperatures, oils, dirt, and sludge.
Hoses degrade from the inside out, which makes detecting their decay difficult. Hoses that continue to degrade develop tiny cracks and pinholes which can lead to ruptures from the pressure, contractions, and exposure to heat.Radiator Hose - When to replace, what does it do
Heater Hose vs. Radiator Hose
Most vehicle cooling systems are comprised of four main hoses.
The upper radiator hose is connected to the thermostat housing and to the radiator. From the bottom of the radiator, is the lower radiator hose that is directed to the water pump. Powered by the vehicle’s water pump, the engine coolant loses its heat after passing through the radiator. Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine.
Heater hoses are smaller hoses that are attached to the heater core, which is located under the dashboard, to supply warmth to passengers in the cabin.
