Tools and Materials Needed:
- New coolant (refer to your owner's manual for the recommended coolant)
- Funnel
- Wrench
- Garden hose
- Safety glasses
- Container to collect the old coolant
Step-by-Step Process:
1. Preparation:
- Ensure your Raptor 660 is on level ground.
- Let the engine cool down completely to avoid burns.
- Wear safety glasses to protect your eyes.
2. Locate the Drain Plug:
- The drain plug for the coolant is typically located at the bottom of the radiator or coolant reservoir.
3. Place the Container:
- Position a suitable container beneath the drain plug to collect the old coolant as it drains out.
4. Drain the Coolant:
- Use a wrench to loosen and remove the drain plug.
- Allow all the old coolant to drain out completely.
5. Close the Drain Plug:
- Once the coolant has drained, reinsert and tighten the drain plug securely.
6. Disconnect the Coolant Reservoir Hose:
- Locate the upper radiator hose or the coolant reservoir hose.
- Disconnect the hose to create an opening for flushing.
7. Flush with Clean Water:
- Connect a garden hose to the open hose fitting.
- Turn on the water and let it flow through the cooling system for several minutes.
- This will help flush out any residual old coolant or contaminants.
8. Reconnect the Hose:
- After flushing with water, reconnect the coolant reservoir hose or the upper radiator hose securely.
9. Refill with New Coolant:
- Use a funnel to carefully add the recommended amount of new coolant to the radiator or coolant reservoir.
- Refer to your owner's manual for the correct coolant type and quantity.
10. Bleed the Air Pockets:
- With the engine off, start squeezing the radiator hoses gently to help remove air pockets.
- Continue squeezing until coolant starts to overflow.
11. Fill the Overflow Tank:
- Check the overflow tank (if your Raptor 660 has one) and fill it to the specified level.
12. Run the Engine:
- Start the engine and let it idle for a few minutes.
- Rev the engine to circulate the coolant throughout the system.
13. Check Fluid Level:
- Let the engine cool down again. Check the coolant level one more time. Adjust if necessary.
14. Test Ride and Check for Leaks:
- Take the Raptor 660 for a short test ride.
- After the ride, inspect the coolant hoses and connections for any signs of leaks.
Remember, flushing the coolant is not only a necessary maintenance task but also an excellent way to help prevent overheating and ensure your Raptor 660 performs at its best. If you have any concerns about the process or if your ATV has specific cooling system requirements, refer to the owner's manual or consult a qualified mechanic.
