GENERAL
This section describes the service procedures required
to keep Jeep vehicles in good running condition. These
services are based on changes in driving conditions, ac
cumulated odometer mileage or time intervals (which
ever comes first), or are unscheduled as required by
changes in usage, handling or performance. The section
is divided into three parts: (1) Maintenance Schedule,
(2) Description of Services according to components
(listed alphabetically), (3) Unscheduled Maintenance.
Maintenance Schedule
Two maintenance schedules are listed: one for Engine
Maintenance; one for Chassis Maintenance (including
body).
The services listed are those which experience and
testing have indicated are most likely needed at the time
or distance intervals shown.
Perform the maintenance services as indicated in the
Engine Maintenance Schedule and the Chassis Main
tenance Schedule. The schedule tells you the com
ponent and required service, followed by the time and/
or distance interval (mileage) at which the service
should be performed, under both normal and heavy-
duty operation. For example:
