Pre- and Post-Trip Inspections and Maintenance
Monthly Post-Trip Inspection
and Maintenance Procedures
WARNING
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. To prevent possible per-
sonal injury, always wash your hands after han-
dling battery parts and related accessories.
1. Clean the batteries.
1.1 Remove any corrosion from the hold-down
and the top of the battery.
NOTICE
Take care to keep the vent plugs tight so that the
neutralizing solution does not enter any of the
battery cells and damage the battery.
1.2 Use a soda solution to neutralize the acid
present, then rinse off the soda solution
with clean water.
1.3 If the battery posts or cable terminals are
corroded, disconnect the terminals from
the posts. Clean them with a soda solution
and a wire brush. After cleaning, connect
the terminals to the battery posts, then
apply a thin coat of petroleum jelly to the
posts and terminals to help retard corro-
sion.
2. Inspect the radiator and heater hoses, including
the clamps and support brackets.
2.1
Make sure the radiator inlet and outlet
hoses are pliable and are not cracking,
weakening, or ballooning.
2.2 Make sure the heater hoses are pliable
and are not cracking or ballooning. Re-
place hoses that show signs of cracking,
weakening, or ballooning.
2.3 Tighten hose clamps as necessary, but do
not overtighten, as hose life can be ad-
versely affected.

2.4 Be sure the hose support brackets are
securely fastened. Make sure the hoses
are not located near sources of wear,
abrasion, or high heat.
IMPORTANT: Replace all hoses, including
heater hoses, at the same time. Service-type
knitted or braided yarn-reinforced neoprene
hose is acceptable. Silicone hoses having an
extended service life can be substituted for the
reinforced neoprene type. See the Freightliner
Service Parts Catalog or contact your Freight-
liner Dealer.
3.
Check the fluid level in the hydraulic brake fluid
reservoir, if so equipped.
If needed, fill the reservoir up to the ridge that
surrounds the reservoir. Use only heavy-duty
brake fluid, DOT 6. See

45/55 reservoir shown)
4. Check the steering wheel for excessive play.
With the front tires pointing straight ahead, turn
the steering wheel until motion is observed at the
front wheels. Align a reference mark on a ruler,
then slowly turn the steering wheel in the oppo-
site direction until motion is again detected at the
wheels. Measure the lash (free play) at the rim of
the steering wheel. See
Fig. 11.15.
