Engine Cooling System
COOLANT
LEVEL
Check coolant level daily at reserve tank
(A)
.
C
he
ck level when engine is cold.
If tank
is
less than half
full,
add
coolant
to
reserve tank (Al, not to radiator.
IMPORTANT: Use a 50/50 mix
of
clean, soft
water
and
anti·freeze. Th
is
ratio
will
protect
engine to temperatures of
_30
°F (-34°
C)
.
Anti-freeze Specification: Ethylene-glycol or
propylene-glycol fully formulated, containing a
pre-cha
rg
e supplemental coolant additive (SeA)
and meeting
ASTM
Designation: D 4985.
Anti-freeze is essential in
any
climate. It
broadens
th
e operating temperature ra
ng
e
by
lowering the coolant freezing point and
by
raising
its boiling point. Anti-freeze also contains
ru
st
inhibitors and other additives
to
prolong engine
life.
IMPORTANT: If
anti-freeze strength
is
not
adequate, do
no
t drain cool
ing
system
to
protect
aga
in
st
freezing. System
may
not drain
completely, and damage cou
ld
result.
RADIATOR
CAP
The radiator cap must fit tightly and
the
cap
gasket must
be
in
good condition to maintain the
7 psi
(58
kPa) pressure
in
the cool
ing
system.
A
CAUTION: To avoid personal
injury
from
hot
coolant
,
do
not
turn
radiator cap
until
engine has
cooled.
Turn
the
cap
to
the
first
notch
to
relieve
pressure before
removing
cap completely.
ANTI-FREEZE
CONCENTRATION
Check the anti-freeze concentration with a tester
once per season, preferably before off-season
storage. Protect the engine to
_30°F (-34°C) with
a
50/50 anti-freeze and water
