If Steam is Corning from Your Engine
A
Steam from an overheated
engine can burn
you badly,
even if you just open the hood. Stay
away from the engine
if you see or
hear steam coming from it. Just
turn it off and get everyone away
from the vehicle until it cools down.
Wait until there is no sign
of steam
or coolant before opening the hood.
If
you keep driving when your
engine is overheated, the liquids in
it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine is
cool.
If No Stem is Coming from Your
Engine:
If you get the overheat warning but see
or hear no steam, the problem may not
be too serious. Sometimes
the engine
can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.

How to Add Coolant to the Coolant
Recovery Tank
(or the Coolant Surge
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
(or coolant surge tank). If you have the
coolant surge tank, be sure
the cooling
system, including the coolant surge
tank
pressure cap, is cool before you do it.
See How To Add Coolant to the 2.2L L4
Engirze at the Radiator or How to Add
Coolant
to the 3.1L V4 Engine ut the
Coolant
Surge Tank later in this section.
A
Adding only plain water to
your cooling system can be
dangerous. Plain water, or some
other liquid like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system
is set for the proper cool an^
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 50150 mix
of clean water and a proper
antifreeze. In cold weather, water can freezt
and crack the engine, radiator,
heater core and other parts Ise
the recommended coolant.

cap when
the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly to
the left until it first stops. (Don’t
press down while turning the
pressure cap.)
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure
left.
2. Then keep turning the pressure cap, 3. Fill the radiator with the proper mix,
but now push down as
you turn it. up to the base of the filler neck.
Remove the pressure cap.
