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