1998 PONTIAC GRAND AM fuel cap

NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t have enough
air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
0 Rough ride
0 Needless damage from road hazards.
When
to Check
Check your tires once a month or more.
Don’t forget your compact spare
tire. It should be at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires
are properly inflated
simply by looking at them. Radial tires
may look
properly inflated even when they’re underinflated.
Be sure to put
the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.

Maintenance Schedule
I Short TripKity Definition I
Follow the Short TripKity Maintenance Schedule if any
one
of these conditions is true for your vehicle:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
0 Most trips include extensive idling (such as frequent
driving in stop-and-go traffk).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle. (With some models, you should never
tow a trailer.
See “Towing a Trailer” in the Index.)
If the vehicle is used for delivery service, police, taxi
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine
oil to break
down sooner.
or other commercial application.
Short TripKity Intervals
Every 3,000 Miles (5 000 km): Engine Oil and Filter
Change (or 3 months, whichever occurs first).
Every 6,000 Miles (10 000 km): Chassis Lubrication
(or
6 months, whichever occurs first). Tire Rotation.
Every 15,000 Miles (25 OOO km): Air Cleaner Filter
Inspection, if driving in dusty conditions.
Every 30,000 Miles (50 000 km): Air Cleaner Filter
Replacement. Fuel Tank, Cap and Lines Inspection.
Every 50,000 Miles (83 0oO km): Automatic Transaxle
Service (severe conditions only).
Every 60,000 Miles (100 000 km): Engine Accessory
Drive Belt Inspection.
Every 100,000 Miles (166 000 km): Spark Plug Wire
Inspection. Spark Plug Replacement.
Every 150,000 Miles (240 000 km): Cooling System
Service (or every
60 months, whichever occurs first).
These intervals only summarize maintenance services.

Maintenance Schedule
Long Tripmighway Definition
Follow this maintenance schedule only if none of the
conditions from the Short TripKity Maintenance
Schedule is true.
Do not use this schedule if the vehicle
is used for trailer towing, driven in a dusty area
or used
off paved roads. Use the Short TripKity schedule for
these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions causes engine oil to break
down slower:
Long Tripmighway Intervals
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every
12 months, whichever occurs first).
Chassis Lubrication (or
every 12 months, whichever
occurs first). Tire Rotation.
Every 30,000 Miles (50 OOO km): Air Cleaner Filter
Replacement. Fuel Tank, Cap and
Lines Inspection.
Every 50,000 Miles (83 OOO km): Automatic Transaxle
Service (severe conditions only).
Every 60,000 Miles (100 000 km): Engine Accessory
Drive Belt Inspection.
Every 100,OOO Miles (166 0oO km): Spark Plug Wire
Inspection. Spark Plug Replacement.
