Flush Cooling System and Changing Coolant (HST Type)
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 and remove
radiator cap. The radiator cap must be removed to completely
drain the coolant.
3. After all coolant is drained, close the drain plug.
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 radiator cap. Install the radiator cap
securely.
7. Fill with fresh water up to the "FULL" mark on the recovery tank.
8. Start and operate the engine for a few minutes.
9. Stop the engine and let cool.
10.Check coolant level of recovery tank and add coolant if
necessary.
IMPORTANT
■
• Do not start engine without coolant.
• Use clean, fresh water and anti-freeze is mixed with water,
the anti-freeze mixing ratio must be less than 50 %.
• Securely tighten radiator cap (1). If the cap is loose or
improperly fitted, water may lead out and the engine could
overheat.
■
Anti-Freeze
If coolant freezes, the cylinders and radiator can be damaged. It
is necessary, if the ambient temperature falls below 0
°
C (32
°
F), to
remove coolant mix it with anti-freeze and full the radiator with it.
1. There are two types of anti-freeze available; use the permanent
type (PT) for this engine.
2. Before adding anti-freeze for the first time, clean the radiator
interior by pouring fresh water and draining it a few times.
3. The procedure for mixing of water and anti-freeze differs
according to the maker of the anti-freeze and the ambient
temperature, basically should be referred to SAE J1034, more
specifically also to SAE J814c.
4. Mix the anti-freeze with water, and then fill in to the radiator.
* At 10 kPa (760 mmHg) pressure (atmospheric). A higher boiling point is obtained
by using a radiator pressure cap which permits the development of pressure within
the cooling system.
