1. Prepare your tools and materials.
- Safety goggles
- Socket set
- Pliers
- Hose clamp pliers
- Funnel
- Container to catch drained coolant (at least 2 gallons)
- New coolant (Banshee requires approximately 1.2 gallons)
- Distilled water
2. Warm up the engine.
- Start the Banshee and let it run for a few minutes until the engine reaches operating temperature. This will help loosen any stuck particles in the radiator.
3. Drain the old coolant.
- Place the drain pan under the Banshee's radiator.
- Locate the radiator drain bolt or petcock (usually at the bottom of the radiator).
- Open the drain bolt or petcock and let all the coolant drain out. Be careful as the coolant may be hot.
4. Remove the radiator cap.
- Locate the radiator cap on top of the radiator.
- Unscrew the radiator cap carefully, allowing any remaining pressure in the system to escape.
5. Flush the radiator.
- Using a garden hose, connect it to the radiator's top opening.
- Turn on the water and let it flow through the radiator until the water coming out of the drain hole runs clear.
- This step helps remove any remaining scale, debris, and old coolant.
6. Reinstall the drain plug or petcock.
- Once the radiator is flushed, close the drain plug or petcock.
7. Refill the radiator.
- Place a funnel on top of the radiator's opening.
- Pour the new coolant into the funnel until the radiator is full.
- Follow the Banshee's coolant fill guidelines to ensure proper levels.
8. Mix 50/50 coolant with water.
- Banshee requires a 50/50 mix of coolant and distilled water.
- Check your coolant to water ratios, as this can vary depending on your location and riding conditions.
9. Burp the radiator.
- With the engine off and the radiator cap removed, start the Banshee and let it run for a few minutes. This will help remove any trapped air in the system.
- Squeeze the radiator hoses gently to help release trapped air.
- Top up the coolant level if needed.
10. Replace the radiator cap.
- Replace the radiator cap securely to ensure a proper seal.
11. Test the system.
- Take the Banshee for a short ride and observe the coolant temperature gauge to ensure it operates within the normal range.
Note: Always refer to the Banshee's service manual for specific instructions and guidelines related to flushing the radiator.
