Engine Air Cleaner/Filter
(3.8L V6 Engine)
SeeEngine Compartment Overview on page 5-12
for the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter every 15,000 miles
(25 000 km) and replace every 45,000 miles
(75 000 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 caked with dirt, a new
lter is required.
To inspect or replace the engine air cleaner/lter do
the following:
1. Loosen the two clips on top of the engine air
cleaner/lter housing and lift the lter cover tabs out
of the housing.
2. Push the housing cover toward the engine,
compressing the hose.
3. Pull out the lter. Inspect or replace the engine air
cleaner/lter.
5-22

4. To reinstall the housing cover, make sure the lter
cover tabs position through the slots in the housing.
A notch on the sides of the lter cover will indicate
the correct engagement.
5. Fasten the two clips on the top of the housing when
you are nished.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air; it helps
to stop ame if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.

Selecting the Right Schedule
First you will need to decide which of the two schedules
is right for your vehicle. Here is how to decide which
schedule to follow:
Short Trip/City Denition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier on top
of your vehicle.
If the vehicle is used for delivery service, police,
taxi or other commercial application.
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.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and Filter
Change (or 3 months, whichever occurs rst).
Every 6,000 Miles (10 000 km):Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection.
Every 30,000 Miles (50 000 km):Throttle Body Bore
and Valve Plates Inspection (V8 engine only).
Every 45,000 Miles (75 000 km):Engine Air Cleaner
Filter Replacement.
Every 50,000 Miles (83 000 km):Automatic Transaxle
Service (severe conditions only).
Every 100,000 Miles (166 000 km):Spark Plug Wire
Inspection (V6 engine only). Spark Plug Replacement.
Automatic Transaxle Service (normal conditions).
Every 150 000 Miles (240 000 km):Cooling System
Service (or every 60 months, whichever occurs
rst). Engine Accessory Drive Belt Inspection.
These intervals only summarize maintenance services.
Be sure to follow the complete scheduled maintenance
on the following pages.
