IMPORTANT
Never pour cold water into a hot engine, since
it
could crack cylinder block or head. Never operate
engine without coolant for even a few minutes.
2)
Flushing cooling system
Flush radiator every
600
hours or annually,
whichever occurs first.
a) Drain cooling system by opening radiator
drain plug on the cylinder block.
b) Close drain plug, and fill system with clean
soft water.
C) Run engine until it reaches operating tem-
perature.
d) Stop engine and drain water out before rust
or sediment settles.
e) Close drain plug, and fill system with a
solution of clean soft water and cooling
system cleaner.
f
)
After using cleaner, flush system with clean
water.
g) Close drain plug, and fill system. Use
CLEAN SOFT water and ethylene glycol
anti-freeze
(full season type).
For non-freezing weather, you can use
Summer Coolant Conditioner.
3)
Preparing for cold weather
If
you drain cooling system to prevent freezing,
first add a suitable
rust
preventive. Run engine to
circulate preventive and leave a protective coating
throughout system.
a) Drain coolant in the radiator, sub-tank and
engine block and flush system.
b)
Close drain plug, and add permanent-type,
ethylene glycol anti-freeze to the radiator.
Fill system with CLEAN SOFT water.
C)
Run engine until
it
reaches operating tem-
perature. Tnis mixes solution uniformly
and circulates
it
through entire system.
IMPORTANT
-
The mixture ratio of anti-freeze must not exceed
40%
to avoid overheating during the summer.
If
you
added anti-freeze more than
40%,
drain
coolant after
the
cold weather
passes.
Determine the ratio according to the lowest
expected
temperature and instruction of its anti-
24084
freeze.
