To Add Coolant
If you need more coolant, add the proper
mix
at the coolant recovery tank.
Add coolant mix at the recovery tank,
but be careful not
to spill it.
I Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105 1tPa) pressure-type cap and
must be tightly installed
to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube
on the radiator
filler neck.
When you replace your radiator
pressure cap, an AC@ cap
is
recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow
of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
I Power Steering Fluid
How To Check Power Steering
Fluid
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
. When the engine compartment is hot,
the level should be
at the HOT mark.
When the engine compartment is
cool, the level should be at the
FULL
COLD mark.

What to Add
Refer to the Maintenance Schedule to
determine what kind of fluid to use. See
Recommended Fluids G Lubricants in
the
Index.
NOTICE:
When adding power steering fluid
or malting a complete fluid change,
always use the proper fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.
Windshield Washer Fluid
To Add
Open the cap labeled WASHER FLUID
ONLY. Add washer fluid until the bottle
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 %
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.

Always use SH or SG Energy
Conserving I1 oils of proper viscosity.
The
“SH” or “SG” designation may be
shown alone or in combination with
others, such as “SH/CD,”
“SH, SG,
CD,” “SG/CD,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 1OW-

inhibitor level and maintains proper
engine operating temperature.
Inspect hoses and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps. Clean the outside of the radiator and
air conditioning condenser. Wash the
pressure cap and neck.
4. Engine Accessory Drive Belt
To help ensure proper operation, we
