NOTICE:
In cold weather, water can freeze and crack the engine, radiat\
or,
heater core and other parts.
So use the recommended coolant.
1. You can remove the coolant surge tank pressure cap when the cooling
system, including the coolant surge tank 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.

7. Then fill the coolant
surge
tank with the
proper mix, up to
the COLD mark.
8. 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 fan(s).
By this time, the coolant level inside
the coolant surge tank may be
lower. If the level is lower, add more of the proper mix to the coolant
surge tank until the level reaches the
COLD mark.

as air trapped in the cooling system, can affect the
coolant level
in the radiator. Check the coolant level when the engine is cold
and follow the steps under “Adding Coolant”
for the proper way to add
coolant.
If you have to add coolant more than four times
a year, have your dealer

Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read the manufacturer’s
instructions before use.
If you will be operating your vehicle in an area
where the temperature may fall below freezing, use
a fluid that has
sufficient protection against freezing.
To Add
Open the cap labeled
WASHER
FLUID
ONLY. Add washer
fluid
until the tank is
full.
NOTICE:
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 3/4 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.
