Description of Emission System Maintenance Jobs
The composition of exhaust emissions is
influenced not only by the special emission
control equipment, but also by various en-
gine components and their adjustments.
Therefore, emission system maintenance
must include these engine components.
Some maintenance jobs are actually only
tests. They are important however, be-
cause they allow early detection of dis-
crepancies which can later lead to
increased exhaust emissions. It is general-
ly less expensive to have such items ad-
justed immediately rather than allowing
them to contribute to costly repairs. The
maintenance intervals have been deter-
mined so that the vehicle, under normal
conditions, should operate properly be-
tween services. 0101 Engine oil and filter change
