Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
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.
Power Steering Fluid
3.lL L82 (Code M) Engine 3.8L L36 (Code K) Engine
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless
you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

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.
Adding Washer Fluid
NOTICE:
0

0
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.
.
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid until the tank is full.
