Engine Compartment Inspection and
Adjustments
IMPORTANT: If replacement of the hood or
bumper is necessary, the replacement compo-
nent must meet or exceed the drag reduction
performance of the originally installed item in
order to maintain compliance with greenhouse
gas and fuel efficiency regulations.
NOTE: Anytime a hood is adjusted, removed, or
reinstalled, the headlamp aim should be
checked.
1.
Inspect the bumper and hood for structural dam-
age, cracks, or wear.
2.
Check the hydraulic clutch reservoir, if equipped.
If necessary, add DOT 4 brake fluid.
3.
Inspect the radiator and heater hoses, including
the clamps and support brackets.
3.1
Inspect the radiator and charge air cooler
for damage and accumulated debris.
Straighten bent or damaged fins to permit
airflow across all areas of the cores.
NOTE: When traveling through areas of high
insect concentration, it may be necessary to
clean the exterior of the radiator or the
charge air cooler core as often as every 200
miles (320 km).
3.2
Make sure the radiator inlet and outlet
hoses are pliable and are not cracking or
ballooning.
3.3
Make sure the heater hoses are pliable
and are not cracking or ballooning.
3.4
Tighten hose clamps as necessary.
IMPORTANT: Do not overtighten hose
clamps, as hose life can be adversely af-
fected.
3.5
Ensure hose support brackets are se-
curely fastened. Make sure hoses are not
located near sources of wear, abrasion, or
high heat.
IMPORTANT: When replacing hoses, install
service-type knitted or braided yarn-reinforced
neoprene hose. Extended-service-life silicone
hoses may also be used. See the Alliance Parts
Catalog at
or
contact your Freightliner Dealer.
4.
Check the steering wheel for excessive play.
4.1
Start the engine. With the front tires
straight ahead, turn the steering wheel
until motion is observed at the front
wheels.
4.2
Align a reference mark on the steering
wheel to a rule, then slowly turn the steer-
ing wheel in the opposite direction until
motion is again detected at the wheels.
4.3
Measure the lash (free play) at the rim of
the steering wheel. Excessive lash exists
if steering wheel movement exceeds 2-1/4
inches (57 mm) with an 18-inch (450-mm)
steering wheel.
4.4
If there is excessive lash, check the steer-
ing system for wear or incorrect adjust-
ment before operating the vehicle.
