2003 PONTIAC GRAND PRIX coolant reservoir

Engine Coolant Heater

Your vehicle may be equipped with an engine coolant
heater. In very cold weather,
0°F (-18°C) or colder,
the engine coolant heater can help. You’ll get easier
starting and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior
to starting your vehicle.
At temperatures above 32°F
(OOC), use of the coolant
heater
is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located below the engine air
cleaner/filter near the coolant reservoir bottle. See
Engine Comparfment Overview on page
5-12
for more information on location.
3. Plug
it into a normal, grounded 1 IO-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the
wrong kind of extension cord could overheat
and cause a fire. You could be seriously injured. Plug the cord into a properly grounded
three-prong 110-volt
AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before
to keep it away
from moving engine parts. If you don’t, it could be
damaged.

Power Steering Fluid
12. 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 arrow on the pressure cap lines up like this.
13. 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. The power
steering fluid reservoir is located in the
engine compartment next to the engine coolant recovery
tank. In the 3800 V6 (Code
K) engine and the 3800 V6
Supercharged (Code
I) engine, the power steering
fluid reservoir sits low in the engine compartment. See
Engine Compartment Overview on page
5- 12.

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. See
Engine Compartment
Overview on page 5-72 for reservoir location.
Adding Washer Fluid
The windshield washer fluid reservoir is located n the
engine compartment on the passenger’s side of the
vehicle near the diagonal cross brace.
Open the cap with the
washer symbol on it.
Add washer fluid until the
tank is full.
Notice:
e

e
a
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 if freezing occurs, which could damage the tank if
it is completely full.
Don’t use engine coolant (antifreeze) in your
windshield washer.
It can damage your
washer system and paint.
