Flushing Cooling System and Changing Coolant
CAUTION
• Do not remove the radiator cap when the engine is hot. Then
loosen cap slightly to the stop to relieve any excess
pressure before removing cap completely.
1. Stop the engine and let cool down.
2. To drain the coolant, open the radiator drain plug (3) and remove
radiator cap (1). The radiator cap (1) must be removed to
completely drain the coolant.
3. After all coolant is drained, close the drain plug (3).
4. Fill with clean water and cooling system cleaner.
5. Follow directions of the cleaner instruction.
6. After flushing, fill with clean water and anti-freeze until the coolant
level is just below the port. Install the radiator cap (1) securely.
7. Fill with coolant up to “FULL” mark on the recovery tank (2).
8. Start and operate the engine for few minutes.
9. Stop the engine and let cool. Check coolant level of recovery tank
(2) and add coolant if necessary.
IMPORTANT
■
• Do not start engine without coolant.
• Use clean, fresh water and anti-freeze to fill the radiator and
recovery tank.
• When the anti-freeze is mixed with water, the anti-freeze
mixing ratio must be less than 50 %.
• Securely tighten radiator cap. If the cap is loose or
improperly fitted, water may leak out and the engine could
overheat.
• Refer to “LUBRICANTS, FUEL AND COOLANT”. (See page
