Flushing Cooling System and Changing Coolant
CAUTION
To avoid personal injury:
• Do not remove radiator cap while coolant is hot. When cool,
slowly rotate cap to the first stop and allow sufficient time
for excess pressure to escape before removing the cap
completely.
1. Stop the engine, remove the key and let it cool down.
2. To drain the coolant, open the radiator drain plug and remove
radiator cap. The radiator cap must be removed to completely
drain the coolant.
3. After all coolant is drained, reinstall the drain plug.
4. Fill with clean soft water and cooling system cleaner.
5. Follow directions of the cleaner instruction.
6. After flushing, fill with clean soft water and anti-freeze until the
coolant level is just below the radiator cap.
Install the radiator cap securely.
7. Fill with coolant up to the
"FULL"
mark of recovery tank.
8. Start and operate the engine for few minutes.
9. Stop the engine, remove the key and let cool.
10. Check coolant level of recovery tank and add coolant if
necessary.
11. Properly dispose of used coolant.
IMPORTANT
• Do not start engine without coolant.
• Use clean, coolant 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.
NOTE
• On cabin type machines, coolant circulates through the
heater. This means that one more liter or so of coolant is
required.
In changing coolant, pour coolant up to the filter port of the
recovery tank. Turn ON the heater (shift the temperature
control lever toward WARM), and run the engine for a while
in order to warm coolant. Then stop the engine.
When coolant has cooled down, some of the coolant in the
recovery tank is sucked. Now the recovery tank is
appropriately filled with coolant.
