Flushing Cooling System and Changing Coolant
• 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 the 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.
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.
• 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 dial 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.
• Do not start engine without coolant.
• Use clean, fresh soft water and anti-freeze to fill the radiator
and recovery tank.
• When the anti-freeze is mixed with water, the anti-freeze
mixing ratio is 50 %.
• Securely tighten radiator cap. If the cap is loose or
improperly fitted, water may leak out and the engine could
overheat.
• Refer to "4. LUBRICANTS, FUEL AND COOLANT" on page
G-10.
