Engine Air Cleaner Service
Indicator - Inspect
(If Equipped)
Some engines may be equipped with a different
service indicator.
Some engines are equipped with a differential gauge
for inlet air pressure. The differential gauge for inlet
air pressure displays the difference in the pressure
that is measured before the air cleaner element and
the pressure that is measured after the air cleaner
element. As the air cleaner element becomes dirty,
the pressure differential rises. If your engine is
equipped with a different type of service indicator,
follow the OEM recommendations in order to service
the air cleaner service indicator.
The service indicator may be mounted on the air
cleaner housing or in a remote location.
