1998 PONTIAC GRAND PRIX coolant reservoir

Engine Coolant Heater (If Equipped)
6
In very cold weather, 0 OF (- 18 O 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.
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
air cleaner near the coolant
reservoir bottle.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
I
A CAUTION:
-
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.

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, a GM 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, a GM thermostat
is recommended.

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.

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.
Fill your washer fluid tank only
Brakes
Brake Fluid
P
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are only
two reasons why the brake fluid level in the
reservoir might go down. The fxst 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 your brake
system fwd, since a leak means that sooner or later your
brakes won’t work well, or won’t work
at all.
