When draining fluids from the engine, place
some container underneath the engine
body.
Do not pour waste onto the grounds, down
a drain, or into any water
source.
Also, observe the relevant environmental
protection regulations when dispos
ing of
a
ntifree
ze.
If it free
zes, coolant can damage the cylinders
and radiator. If the ambient temperature falls
below 0 (32℃
°
F) or before a long-term storage,
let out cooling water completely, or mix fresh
water with long-life coolant and fill the radiator
and recovery tank with the mixture.·
1.
Long-life coolant (hereafter LLC) comes in
several types. Use ethylene glyc
ol(EG)
type for
this engine.
2.
Before employing LLC-mixed c
ooling
w
ater, fill the radiator with fresh water
and
em
pty it again.
Repeat this procedure 2 or 3 times to
clean up the in
side.

The procedure for the mixing of water and
antifreeze differs according to the ma
ke of
the
antifreeze and the ambien
t
te
mperature. Refer to SEA J1034
standard, more specifically also to SAE
J814c
.
IM
PORTANT:
When the antifreeze is mixed with water, the
an
tifreeze mixing ratio must be less than
50%.

A higher boiling point is obtained by using
a radiator pressure cap which permits the
development of pressure within the

) Add only water if the mixture reduces in
amount by evaporat
ion.

) If there is a mixture leak, add the LLC
of
t
he same manufacturer and type in the
same mixture percentage

er add any long-life coolant of
different manufacturer.(Different bra

and
the engine may fail to perform as

. When the LLC is mixed, do not employ
any radiator cleaning agent. The LLC
contains anticorrosive agent. If mixed with
the cleaning agent, sludge may build up
,
a
dversely affecting the engine part
s.

. The vehicle’s genuine long-life coolant has
a service life of 2 years. Be sure to
change the coolant every 2 years.
NOTE:
The above data represent indu

col content in the concentrated
antifreeze
.
When the coolant level drops due to
evaporation, add water only to keep the
antifreeze mixing ratio less than 50%. In
case of leakage, add antifreeze and water
in the specified mixing ratio before filling
into the radiator
