you. Keep hands, clothing and tools away from
any underhood electric fan.

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.
When the coolant
in the coolant recovery tank is at the
COLD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing you can
try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you
do it.

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.

How to Add Coolant to the Radiator
I NOTICE:
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
1. You can remove the
radiator pressure cap
when the cooling
system, including the
radiator pressure cap and
upper radiator hose, is
no longer hot. Turn the
pressure cap slowly
counterclockwise 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, but now
push down as you turn
it. Remove the
pressure cap.

4. Fill the radiator with the
proper
mix, up to the
base of the filler neck.
If you see a stream of
coolant coming from an
air bleed valve, close the
I
valve. Otherwise, close
the valves after the
radiator is filled.
5. Rinse or wipe any spilled coolant from the engine
and compartment.

filler neck may be lower. If the level is lower, add
.more of the proper
mix through the filler neck until
the level reaches the base of the filler neck.

10. 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 arrows on the
pressure cap line up
like this.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the
COLD mark
when the engine is cold.

A CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and' scalding liquids to blow out and burn you
badly. With the coolant recovery tank,-you
will
almost never have to add doolant at the radiator.

Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full. Brakes
Brake Fluid
When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system.
Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion, which could damage
the tank
if it is completely full.
Don’t use radiator antifreeze in your
windshield washer.
It can damage your
washer system and paint.

There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluid
level goes back up. The other reason is that fluid
is
leaking out of the brake system. If it is, you should have
