A car is similar to a human in the way it breathes, burns energy and
expels waste. Changing an air filter on your car is a vital necessity
and one which if left for too long, restricts the car's breathing and
can cause major problems. Having new and regularly replaced air
filters, ensures your car's engine has fresh, unimpeded air flowing
Here is how to change your car's air filter:
Purchase the correct air filter for your car, model and engine size.
Consult your owner's handbook to retrieve the part number. Have the
correct tools for the job at hand before you start, which are: a
flat-blade screwdriver, a Phillips screwdriver and an air hose
Secure the car by placing the the gear lever into Park and by
applying the parking brake. Open the bonnet (hood) using the in-car
bonnet release and secure it with the prop rod.
The air filter is usually shrouded with plastic tubing on the top of
the engine. Older cars usually have large, circular compartments, while
new, fuel injected cars have a square air filter housing. To make sure,
check the owner's handbook for reference.
Loosen the air filter housing, hose clamps and screws (making sure
you remember or number them in there respective place). Take out the
paper, gauze or cotton based air filter.
Clean out the filter's housing, using an air compressor or a dry
cloth if this is not an option. Vacuum out any loose dirt and dust,
ensuring there are no particles left.
Install the new filter, ensuring it is in the same direction and it is exactly the same as the old filter unit.
Replace the air filter housing and all of the retaining screws and
clamps. Make sure the housing is on straight and is secured. If it is
not, then it could cause poor fuel efficiency.
Double check all of the screws, clamps and housing parts are
replaced properly, shut the bonnet and start the engine to ensure there
are no strange noises.
Check the filter after 200kms to ensure all of the fixtures are
still tight. Re-tighten if necessary. Remember to change you filter
every 15,000km or once a year.
