L AUTION
-
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t do anything else until it cools down.
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.
5-18

, ,- CAUTION:
~ Heater and radiator hoses, and other engine
1 parts, can be very hot. Don’t touch them. If you
l do, you can be burned.
Don’t run the engine
if there is a leak. If you run
1 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.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fan is running.
If the
engine is overheating, the fan should be running.
If it
isn’t, your vehicle needs service.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge
tank pressure cap, is cool
before you do it. (See “Engine Coolant” in the Index
for more information.)
5-19

A CAUTION:
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 mixture will. 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 wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
A 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. Don’t spill coolant on a hot engine.

3. Then fill the coolant surge tank with the proper
mixture, up
to FULL COLD, or just above the small
cylinder at the base
of the opening.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more
of the proper mixture to the coolant surge tank
until the level reaches
FULL COLD, or just above
the small cylinder at the base of the opening.

Filling a Portable Fuel Container
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if this
occurs.
To help avoid injury to you and others:
0 Dispense gasoline only into approved
containers.
0 Do not fill a container while it is inside a
vehicle, in
a vehicle's trunk, pickup bed or
on any surface other than the ground.

the nozzle. Contact should be maintained
until the filling
is complete.
Bring the fill nozzle in contact with the
Don't smoke while pumping gasoline.
Checking Things Under the Hood
A "P 3N:
&I - --
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.
