How to Add Coolant to the
Coolant Recovery Tank
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant recovery tank, but
be careful not to spill it.
Occasionally check the coolant level
in the radiator. For information on
how to add coolant to the radiator,
see Cooling System on page 9-19 .
{CAUTION
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol,
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
{CAUTION
Adding only plain water to your
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
(Continued)
CAUTION (Continued)
Your vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, your engine
could get too hot but you would
not get the overheat warning.
Your engine could catch fire and
you or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and a proper
coolant.
Notice: In cold weather, water
can freeze and crack the engine,
radiator, heater core and other
parts. Use the recommended
coolant and the proper coolant
mixture.

5. Put the cap back on the coolantrecovery tank, but leave the
pressure cap off.
6. Start the engine and let it run until you can feel the upper
radiator hose getting hot. Watch
out for the engine cooling fan.
7. By this time, the coolant level inside the radiator filler neck may
be lower. If the level is lower,
add more of the proper coolant
mixture through the filler neck
until the level reaches the base
of the filler neck.
8. Then replace the pressure cap. At any time during this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the ears on the
pressure cap are in line with
the vent tube.Engine Overheating
A coolant temperature gage is
located on the vehicle’s instrument
panel. See Engine Coolant
Temperature Gage on page 4-11 .
Check to see if the electric engine
cooling fan is running. If the engine
is overheating, the fan should be
running. If it is not, the vehicle needs
service.
If no problem is apparent, but the
coolant level is not at or above the
FULL mark, add a 50/50 mixture
of clean, drinkable water and
DEX-COOL
®coolant at the coolant
recovery tank. See Engine Coolant
on page 9-19 for more information
about the proper coolant mixture.
If the coolant inside the coolant
recovery tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
If Steam Is Coming From Your
Engine
{CAUTION
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 you open 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.
Notice: If the engine catches
re because of being driven with
no coolant, your vehicle can be
badly damaged. The costly repairs
would not be covered by the
vehicle warranty.
