Tips From the Pros
- Air Filter Replacement

The following information is general in nature. It should not be used as your entire source of information when working on your vehicle. Details on your particular vehicle can be found in your Haynes repair manual.
Caution: Make sure the engine is off and cool before beginning this job.
STEP 1

The air filter is located inside a housing in the engine compartment, usually in the left or right front corner. On most late-model vehicles, the filter housing is box or drum-shaped. It is located at the end of an intake duct that runs to the engine.

STEP 2

To get to the air filter, remove the screws or clips, then lift the cover off the air filter housing.

STEP 3

On some early-model vehicles, the air filter is located on top of the engine. Unscrew the wing-nut from the top of the cover and check to see if there are clips along the side of the pan-shaped housing.

Early style air filter housings use a wing-nut (1) and sometimes clips along the side (2) to secure the cover
STEP 4

With the air filter cover removed, you should have easy access to the air filter.

STEP 5

Inspect the outer surface of the filter element. If it is dirty, replace it. Remember that a dirty air filter restricts airflow and decreases fuel mileage, so reinstalling a borderline air filter is a false economy. While the cover is off, be careful not to drop anything down into the housing.

Caution: Never drive the vehicle with the air cleaner removed. Excessive engine wear could result and backfiring could even cause a fire under the hood.
STEP 6

Wipe out the inside of the air filter housing with a clean rag.

STEP 7

Place the new filter into the housing, making sure it seats properly. Also be sure the filter is installed in the proper orientation (the same as the old filter). To aid installation, some filters are marked with an arrow to indicate the direction of airflow - towards the engine.

STEP 8

Reverse the removal steps, and you're done!

haynes client testimonials
Ever since I bought my first truck, the first thing I got was a Haynes manual. Since that truck, I've owned 5 other vehicles. Without my Haynes manuals, I wouldn't have got out of some pretty sticky situations. I remember my dad sending me off to pick up my first manual. Ever since then, they have been a huge life saver!! So you can easily say, I'm a dedicated die hard fan from day one!!Thanks!
