What is the difference between upper and lower radiator hoses?

If you were to place them side by side, you’d find that they were different lengths and different shapes. They also do different jobs. The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes.

The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes. When it reaches the bottom, it moves out of the radiator through the lower hose and back into the engine to start the cycle once more.

What makes the air flow over a radiator?

Metal fins allow the heat absorbed by the coolant to radiate outward, where it is wicked away by moving air. Air flows over the radiator from two sources – the cooling fan (or fans) blow air over the radiator when it reaches a certain temperature. Air also flows over the radiator when you’re traveling down the road.

Why is there an anti collapse spring in the lower radiator hose?

The truth is, you must have an anti-collapse spring in the lower radiator hose if you have an older vehicle with a conventional cooling system. Because the lower radiator hose channels coolant to the water pump and engine, it is susceptible to negative pressure and collapse at high rpm. The anti-collapse spring prevents that from happening.
