BFlushing Cooling System and Changing
Coolant
To avoid personal injury or death:
A 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.

heater. This means that one more liter or so of coolant
is required.
In changing coolant, pour coolant up to the filler 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.
