1. Gather your materials.
- Replacement rubber hose (make sure it's the same size as the old hose)
- Hose clamps (2)
- Pliers
- Screwdriver
- Funnel
- Antifreeze (make sure it's the right type for your car)
2. Prepare your car.
- Park your car on a level surface.
- Turn off the engine and allow it to cool down completely.
- Open the hood of your car.
3. Locate the leaking hose.
- The leaking hose is likely located near the top of the engine, on the side closest to the radiator.
- It is usually a small, black rubber hose.
4. Remove the old hose.
- Use the pliers to loosen the hose clamps on both ends of the old hose.
- Once the hose clamps are loose, slide them off the hose.
- Pull the old hose off the engine.
5. Install the new hose.
- Slide the new hose onto the engine.
- Make sure the hose is seated properly on the engine.
- Slide the hose clamps onto the new hose and tighten them using the pliers.
6. Add antifreeze.
- Use the funnel to add antifreeze to the radiator.
- Add enough antifreeze to bring the level up to the "full" mark on the radiator.
7. Start the engine and check for leaks.
- Start the engine and let it run for a few minutes.
- Check for leaks around the new hose.
- If there are no leaks, turn off the engine and close the hood of your car.
Your antifreeze leak should now be fixed.
