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 rust
inhibitor.
5. Follow the rust inhibitor manufac-
ture's instructions.
6. After flushing, fill with clean water
and anti-freeze until the coolant level
is just below the port.
Install the radiator cap securely.
7. Fill with coolant up to the "FULL"
mark on the recovery tank.
8. Start and operate the engine for few
minutes.
9. Stop the engine and let cool.
10. Check coolant level of recovery
tank and add coolant if necessary.

ANTI-FREEZE
If cooling water freezes, it can damage
the engine and radiator. It is necessary,
if the ambient temperature falls below
0° C (32° F), to remove cooling water
after operating or to add anti-freeze to
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 make of the anti-freeze and the
ambient temperature, basically it
should be referred to SAE J1034
standard, more specifically also to
SAE J814C.
4. Mix the anti-freeze with water, and
7.4
then fill into the radiator.

PERIODIC SERVICE
* At 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.
NOTE
The above date represents indus-
try standards that necessitate a
minimum glycol content in the con-
centrated anti-freeze.
When the cooling water level drops
due to evaporation, add water only.
In case of leakage, add anti-freeze
and water in the specified mixing
ratio.
Anti-freeze absorbs moisture. Keep
unused anti-freeze in a tightly
sealed container.
Do not use radiator cleaning agents
when anti-freeze has been added
to the cooling water. (Anti-freeze
contains an anti-corrosive agent,
which will react with the radiator
cleaning agent forming sludge
which will affect the engine parts.)
