Things You'll Need:
- Catch can
- Screwdriver
- Pliers
- Knife

Step 1
Let the engine cool down for at least an hour after driving. Place a bucket or catch can under the drain plug and let out enough coolant to allow removal of the hoses without leaking. Upper hose replacements need little fluid removed while lower hoses need the radiator drained.
-
Step 2
Use pliers or a nut driver to loosen the hose clamps and pull them down the hose until they clear the nipple. Pull or twist the hose ends until they clear the connector. Cut the hose end with a knife if it doesn't slip off easily.
-
Step 3
Dip the ends of the new hose in clean coolant and place the clamps over each end. Push the hose onto the nipples, turn the hose around if it doesn't slide on easily. Hoses are often different dimensions on each end and only fits one way.
-
Step 4
Tighten the hose clamp by using pliers on a spring clamp or a nut driver. Ensure the drain plug is closed and fill the radiator with coolant. Close the system by replacing the radiator cap and turn the truck on. Add coolant as needed when the system circulates.
