Attach and clamp one end before the other end. Then double-check if the hose will interfere with other moving parts of the engine such as the fan. Also, ensure that the clamps are tightly fixed by giving the radiator hose a little pull.

  • If the previous coolant you drained is still clean, Then you can pour it back into the system. Else refill with another 50/50 mixture of fresh coolant and water.
  • Now you can dispose of old items.
