What connects the radiator hose to the engine?

The radiator hose transfers coolant from an engine’s water pump to the radiator. An upper hose connects the top of the radiator to the top of the engine. A lower hose connects the bottom of the radiator to the water pump, which keeps coolant flowing through the system.

How do you replace a upper radiator hose?

Difficulty

  1. Open the hood and locate the vehicle’s radiator.
  2. Inspect the upper radiator hose.
  3. With the engine off and cold, install the cooling system pressure tester.
  4. Inspect the cooling system for leaks.
  5. Place a drain pan under the radiator.
  6. Remove the upper radiator hose clamps.

Does upper radiator hose go in or out?

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.

Where are the lower and upper radiator hoses located?

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.
