MAINTENANCE 6-27
Replace the hoses and clamps.
(See “Checking Radiator Hose and Clamp”
in every 200 hours maintenance.)
REPLACING POWER STEERING
HOSE
Replace the hoses and clamps.
(See “ Checking power steering line” in
every 200 hours maintenance.)
REPLACING FUEL HOSE
Replace the hoses and clamps.
(See “ Checking Fuel line” in every 100
hours maintenance.)
REPLACING RADIATOR HOSE
(WATER PIPES)
* 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
SAE J1034 and SAE J814c are indus-
try standards that necessitate a mini-
mum 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.)
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.
