Radiator and Heater Hoses In a typical automotive cooling system, you’ll find at least 4 main hoses. First, the upper radiator hose leads directly from the thermostat housing (on the intake manifold or cylinder head) into the top of the radiator. Attached to the bottom of the radiator is a lower radiator hose.

How does the overflow hose in a radiator work?

An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added). As pressures within the cooling system change with coolant temperature, a valve in the radiator cap allows coolant to flow back into the reservoir to relieve pressure buildup which naturally occurs.

Why are the lower coolant hoses so durable?

Note that because lower coolant hoses are exposed to heavy amounts of suction from the engine’s water pump, a resilient spring is wound around the inside of them to ensure the hose does not collapse and block the flow of coolant. Like most components of modern hoses, these springs are quite durable over the long term.

How are car radiator and heater hoses degrade?

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. Most vehicle cooling systems are comprised of four main hoses.

Why is my water pump and thermostat not working?

The radiator, water pump, and thermostat are definite possibilities, but there are a few others that are possible also. A faulty cooling fan is the first thing that comes to mind, but it could also be a head gasket issue, clogged coolant passages inside the engine, or faulty radiator hoses.
