1. Place the ATV on a level surface.
2. Remove panels D and F. (the top engine and left side engine panels).
3. Place a container under the engine, and then remove the coolant drain bolt (1).
4. Remove the top panels over the battery to expose the radiator cap.
5. Remove the radiator cap.
6. Remove the coolant reservoir cap.
7. Disconnect the hose on the coolant reservoir side, and then drain the coolant from the coolant reservoir.
8. After draining the coolant, thoroughly flush the cooling system with clean tap water.
9. Replace the coolant drain bolt washer if it is damaged, install the coolant drain bolt, and then tighten it to the specified torque.
Tightening torque: Coolant drain bolt: 10 NM (1.0 m kgf, 7.2 ft lbf)
10. Connect the coolant reservoir hose.
11. Pour the recommended coolant into the radiator until it is full.
12. Pour the recommended coolant into the reservoir to the maximum level mark, and then install the reservoir cap.
Antifreeze/water mixture ratio: 1:1
Recommended antifreeze: High-quality ethylene glycol antifreeze containing corrosion inhibitors for aluminum engines.
Coolant quantity:
Radiator capacity (including all routes):
1.99L (2.10 US qt)
Coolant reservoir capacity (up to the max level mark):
0.17L (0.18 US qt)
13. Loosen the water pump air bleed bolt (1), without removing it, to allow all the air to escape from the air bleed bolt hole.
14. When coolant begins to flow out of the bolt hole, tighten the water pump air bleed bolt to the specified torque.
Tightening torque: Water pump air bleed bolt: 10Nm (1.0 m kgf, 7.2 ft lbf)
15. Remove the right side engine plastic
16. Loosen the clamp screw and then remove the V-belt cooling duct.
17. Loosen the cylinder head air bleed bolt, without removing it, to allow all of the air to escape from the air bleed bolt hole.
18. When coolant begins to flow out of the bolt hole, tighten the cylinder head air bleed bolt to the specified torque.
Tightening torque: Cylinder head air bleed bolt: 10Nm (1.0 m kgf, 7.2 ft lbf)
19. Start the engine and let it idle for ten minutes.
20. Rev the engine five times.
21. Pour the recommended coolant into the radiator until it is full.
22. Stop the engine and allow it to cool. If the coolant level has dropped after the engine has cooled, add sufficient coolant until it reaches the top of the radiator and then install the radiator cap.
23. Start the engine and the check for coolant leakage.
24. Install the V-belt cooling duct and then tighten the clamp screw.
25. Install the panels.
