The coolant level should be at or above
FULL COLD. If it isn’t, you may have
a leak
in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system. II
A Heater and radiator hoses, and
L other engine parts, can be very
hot. Don’t touch them.
If you do,
you can be burned. ~
Don’t run the engine if there is a
leak. If
you run the engine, it could
lose
all coolant. That could cause
an engine fire, and you could be
burned. Get any leak fixed before
you drive the vehicle.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t
at or above FULL
COLD,
add a 50/50 mixture of clean
water
(preferably distilled) and a proper
antifreeze at the coolant recovery tank.
(See “Engine Coolant”
in the Index for
more information about the proper
coolant
mix.)
A Adding only plain water to
L your cooling system can be
dangerous. Plain water, or some
I
other liquid like alcohol, can boil
before the proper coolant
mix will.
Your vehicle’s coolant warning
system
is set for the proper coolant
mix. With plain water or the wrong
mix, your engine could get too hot
but you wouldn’t get the overheat
warning. Your engine could catch
fire and you or others could
be
burned. Use a 50/50 mix of clean
water
and a proper antifreeze.

tank is at or above

one more thing you can

cool before you do
it.

CAUTION:
Steam and scalding liquids
from a hot cooling system can
blow out and burn you badly. They
are under pressure, and
if you turn
the radiator pressure cap
- even a
little
- they can come out at high
speed. Never
turn the cap when the
cooling system, including the
radiator pressure cap,
is hot. Wait
for the cooling system and radiator
pressure cap to cool
if you ever
have to turn the pressure cap.
