What size is lower radiator hose?

What size are coolant hoses?

Coolant Hose Heater hose is generally ½, 5/8, and ¾-inch in diameter. There are different types of heater hose, from standard to heavy duty.

Are radiator hoses supposed to be hard or soft?

A radiator hose in good condition should feel firm, but not hard. A radiator hose in poor condition feels very hard, spongy, or soft. You may find a single soft spot as opposed to the entire hose being soft. A soft hose or a hose with a soft spot should be replaced.

How do I know if my lower radiator hose is bad?

If you suspect either radiator hose is failing, watch for the following symptoms:

  1. Leaking coolant. If you notice green fluid beneath your vehicle, chances are your vehicle is leaking coolant.
  2. Engine overheating.
  3. Low coolant.
  4. Collapsed radiator hose.
  5. Radiator hose is broken.

What is a lower radiator hose?

The lower radiator hose is primarily a suction hose. The water pump, as it spins, draws coolant from the radiator into the engine. This creates an area of low pressure at the bottom of the radiator, which can cause an ordinary hose to collapse.

A lower hose connects the bottom of the radiator to the water pump, which keeps coolant flowing through the system.

What does a lower radiator hose do?

The upper radiator hose carries coolant from the top of the radiator to the top of the engine to keep it from overheating. The lower radiator hose connects the bottom of the radiator to the water pump, which pumps the coolant throughout the system.

What is the difference between upper and lower radiator hose?

The upper radiator hose is where the hot coolant enters the radiator from the engine. 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.
