Flush Cooling System And Changing Coolant; Anti-Freeze - Kioti DK55 Manual

FLUSH COOLING SYSTEM AND
CHANGING COOLANT
1. Stop the engine and let cool down.
2. To drain the coolant, open the radia-
tor drain plug and remove radiator
cap. The radiator cap must be re-
moved to completely drain the coolant.
3. After all coolant is drained, close the
drain plug.
4. Fill with clean water and cooling sys-
tem 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 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 cylinders 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 pour-
ing 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 ambi-
ent temperature, basically it should be
referred to SAE J1034 standard, more
specifically also to SAE J814c.
4. Mix the anti-freeze with water, and
then fill into the radiator.

* 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 industry
standards that necessitate a minimum
glycol content in the concentrated 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 con-
tains an anti-corrosive agent, which
will react with the radiator cleaning
agent forming sludge which will af-
fect the engine parts.)
