Peterbilt 579 - Fluid Level and Refill

STEERING SYSTEM
take your truck to an authorized Fluid Level and Rell
dealer for evaluation.
Have the
power steering uid and
lters changed
at an authorized dealer.
CAUTION
When adding uid, be sure to use uid
of the same type. While many u
-
ids have the same description and in-
tended purpose, they should not be
mixed due to incompatible additives.
Mixing incompatible uids may lead to
equipment damage.
• Check and completely change the
uid level
according to Preventive
Maintenance Schedule
on page
5-12. Use
the following procedure:
NOTE
Before removing
reservoir cover, wipe
outside of cover so that no dirt can fall
into the reservoir.
• Maximum/Minimum level is
indicated on the reservoir. These
same levels are also indicated by
two lines on the dipstick in the
reservoir.
• There are two ways to check
whether the power steering uid
is at its proper level. Both checks
are with the engine NOT running.
1. If you
check the uid with the
engine and steering system
COLD, the uid level should be
at/or above the Minimum indicator
level and should generally not
exceed the middle point between
Maximum and Minimum level
indicators.
2. If you
check the uid with the
engine and steering system
WARM, the uid should NOT
exceed the Maximum level
indicator and should generally
not drop below the middle point
