COOLANT
Coolant Level
Check the coolant
level
in the reserve
tank when
the engine
is at normal
operating
temperature.
It should
be between
the
MAX and MIN marks.
If the coolant
level is near the MIN mark, add coolant
to bring it up to the MAX
mark.
If there is no coolant
in the reserve tank, the cooling
system should
be checked
for leaks and repaired
if necessary.
Coolant
must then be added to the radiator
and reserve
tank.
m
The coolant is hot and under pressure and severe scalding could
result. Never remove the radiator cap when the engine is hot.
Wait until the engine
is cool, then turn the radiator
cap counterclockwise
until
it stops. DO NOT PRESS DOWN WHILE TURNING THE CAP. After any remaining
pressure
has been relieved,
remove the cap by pressing
down and again turning
it counterclockwise.
Add enough
coolant
to fill the radiator,
and reinstall
the cap. Fill the reserve tank
once the engine
reaches
normal
operating
temperature.

Recommendation
Use high
quality
ethylene
glycol
antifreeze
that
is specifically
formulated
for use in aluminum
engines.
Mix the antifreeze
with
low-mineral
drinking
I
water
or distilled
water.
A 50/50
mixture
of ethylene
glycol
antifreeze
and water
is recommended
for most
temperatures
and provides
good
corrosion
protection.
A higher
concentration
of antifreeze
decreases
cooling
efficiency
and is recom-
mended
only
if additional
protection
against
freezing
is needed.
A concen-
tration
of
less
than
40%
antifreeze
will
not
provide
proper
corrosion
protection.
(1
The use of unsuitable
antifreeze,
hard water,
or salt water
may
cause corrosion damage that will shorten the life of the engine.
