The air filter is designed to prevent
potentially harmful substances entering into the emissions
system. The air filter should be checked regularly to ensure
that it is kept clear.
Checking air filter
Locating the air filter
The air filter will be located inside the engine bay. On older
cars the air filter is located in a housing right on top of the
engine. On newer cars it tends to be located to the side of the
engine compartment.
If you are unsure please consult your owners manual. The air
filter will generally be located inside a plastic housing with
an air flow pipe running towards the engine.
The plastic housing usually has several clips that you can
remove to gain access to the actual filter. The filter is
constructed of mainly paper with a plastic structure. On
removal you should expect the filter to be dirty. you need to be
able to make a judgment as to how dirt is to dirty.
If the filter is just discoloured then it is ok. In most cases
simply tap the filter on the ground or other surface to remove
any real debris such as dirt or dust. Once you have done this
you can simply re-fit the filter and re-secure the housing
clips.
If the filter is really soiled then it may be best to replace
the filter. any good parts supplier will be able to supply the
correct filter for your car. Make sure you know the make, model
and year when you call or pop in. Most parts stores will carry a
stock of all popular filters so you should be ale to get your
new filter straight away.
Fitting a new filter is the reverse of removal. If your filter
has not been replaced in a year then you may be best to simply
replace it.
A very contaminated air filter can lead to excessive fuel
consumption. It is therefore important to regularly check your
filters condition.
