2004 PONTIAC GRAND PRIX air filter

Outlet Adjustment
Rotate and turn the air
outlets, located in the
middle and at each
outboard side of the
instrument panel,
to adjust the direction
of the air¯ow.
See
Instrument Panel Overview on page 3-2for
additional information on location.
Operation Tips
·
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ¯ow of air into your vehicle.
·Use of non-GM approved hood de¯ectors may
adversely affect the performance of the system.
·Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
·If the air¯ow seems low when the fan is at the
highest setting, the passenger compartment air ®lter
may need to be replaced. See ªPassenger
Compartment Air Filterº following, for more
information on this ®lter.
Passenger Compartment Air Filter
The passenger compartment air ®lter is located
underneath the inlet grille, which is located under
the passenger side windshield wiper arm.
The ®lter traps most of the pollen from entering the
climate control system. Similar to the engine's air ®lter,
it may need to be changed periodically to insure
system performance. See
Part A: Scheduled
Maintenance Services on page 6-4for information
on scheduled changes for this ®lter.

How to Check and Add Oil
Park the vehicle on a level surface. Check oil only when
the engine is cold. Allow the engine to cool two to
three hours after running.
{CAUTION:
If you remove the supercharger oil ®ll plug
while the engine is hot, pressure may cause
hot oil to blow out of the oil ®ll hole. You may
be burned. Do not remove the plug until the
engine cools.
1. Clean the area around the oil ®ll plug before
removing it.
2. Remove the oil ®ll plug.
3. The oil level is correct when it just reaches the
bottom of the threads of the inspection hole.
4. Replace the oil plug with the O-ring in place.
Tighten to 88 lb-in (10Y).
Engine Air Cleaner/Filter
The engine air cleaner/®lter is located in the engine
compartment on the driver's side of the vehicle.
See
Engine Compartment Overview on page 5-12for
more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter every 15,000 miles
(25,000 km) and replace every 30,000 miles (50,000 km).
If you are driving in dusty/dirty conditions, inspect the
®lter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter, remove the ®lter from
the vehicle and lightly shake the ®lter to release
loose dust and dirt. If the ®lter remains ªcakedº with dirt,
a new ®lter is required.

It is also important to check your oil regularly and keep
it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-16for information on resetting the system.

See the mileage intervals following for additional
services that may be performed with an engine oil
change. After the services are performed, record the
date, odometer reading and who performed the service
on the maintenance record pages in Part E of this
schedule.
