Foreword
Scheduled maintenance provides a key element for the safe operation of your vehicle. A proper
maintenance program also helps to minimize downtime and to safeguard warranties. This maintenance manual provides information necessary for years of safe, reliable, and cost-efficient vehicle
operation.
IMPORTANT: The maintenance operations in this manual are not all-inclusive. Also refer to
other component and body manufacturers’ instructions for specific inspection and maintenance instructions. A listing of many OEM websites of vehicle component or system
providers can be found in the 122SD and Coronado Workshop Manual, Section 00.02.
Perform the operations in this maintenance manual at scheduled intervals. Perform the pretrip and

operations listed at the intervals scheduled in those manuals. Your Freightliner Dealership has the
qualified technicians and equipment to perform this maintenance for you. They can also set up a
scheduled maintenance program tailored specifically to your needs. Optionally, they can assist you in
learning how to perform these maintenance procedures.

Noise Emission Controls Maintenance: 00–07
Noise Emission Control
Maintenance
Federal Law, Part 205:
Transportation Equipment Noise
Emission Controls
Part 205, Transportation Equipment Noise Emission
Controls, requires the vehicle manufacturer to furnish, with each new vehicle, such written instructions
for the proper maintenance, use, and repair of the
vehicle by the ultimate purchaser to provide reasonable assurance of the elimination or minimization of
noise-emission-control degradation throughout the
life of the vehicle. In compliance with the law, the
noise emission controls maintenance information in
each applicable group of this manual, in conjunction
with the vehicle workshop manual, provides these
instructions to owners.
Recommendations for
Replacement Parts
Replacement parts used for maintenance or repair of
noise emission controls should be genuine Freightliner parts. If other than genuine Freightliner parts
are used for replacement or repair of components
affecting noise emission control, the owner should be
sure that such parts are warranted by their manufacturer to be equivalent to genuine Freightliner parts in
performance and durability.
Freightliner Noise Emission
Controls Warranty
Refer to the vehicle owner’s warranty information
book for warranty information concerning noise emission controls.
the purpose of noise control, prior to its sale or
delivery to the ultimate purchaser, or while it is in
use.
2. The use of the vehicle after such device or element of design has been removed or rendered
inoperative by any person.
Among those acts presumed to constitute tampering are the acts listed below:
A. Removal of engine noise-deadening panels.
B. Removal of cab-tunnel or hood noise-
deadening panels.
C. Removal of, or rendering inoperative, the en-
gine speed governor so as to allow engine
speed to exceed manufacturer’s specifications.
D. Removal of, or rendering inoperative, the fan
clutch, including bypassing the control on
any thermostatic fan drive to cause it to operate continuously.
E. Removal of the fan shroud.
F.Removal of, or rendering inoperative, ex-
haust components, including exhaust pipe
clamping.
G. Removal of air intake components.
Maintenance Instructions
Scheduled intervals are in the maintenance tables in
this group. A "Verification of Inspections Log (Groups
01, 20, and 49)" follows, and should be filled in each
time noise emission controls on the vehicle are maintained or repaired.
Tampering with Noise Controls is
Prohibited
Federal law prohibits the following acts or the causing thereof:
1. The removal or rendering inoperative by any person (other than for purposes of maintenance,
repair, or replacement) of any device or element
of design incorporated into any new vehicle for

01–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
When working on the vehicle, shut down the engine, set the parking brake, and chock the tires.
Before working under the vehicle, always place
jack stands under the frame rails to ensure the
vehicle can not drop. Failure to follow these steps
could result in serious personal injury or death.
01–01 Engine Drive Belt
Inspection
Worn or loose drive belts may cause engine overheating or loss of alternator power. Excessive tension, or too little tension on the belt may result in excessive and premature belt wear or accessory
bearing failure. Serpentine belts are retained by a
belt tensioner that requires no tension adjustment.
Replace the drive belt if any conditions described
below are found. To inspect a belt, gently twist it to
view the belt sidewalls and bottom.
IMPORTANT: For EPDM rubber drive belts, do
not rely on cracking as an indicator of belt wear.
EPDM rubber drive belts resist cracking better
than Neoprene belts. A better indicator of wear
on EPDM belts is material loss.
Belt and Pulley Inspection
1. Inspect the belt for glazing. Glazing is represented by shiny sidewalls, and is caused by friction created when a loose belt slips in the pulleys. It can also be caused by oil or grease on
the pulleys.
2. Check the belt for ply separation. Oil, grease, or
belt dressing can cause the belt to fall apart in
layers. Repair any oil or coolant leaks that are
affecting the belts before replacing the drive
belts. Do not use belt dressing on any belt.
3. Check the belt for a jagged or streaked sidewall.
Jagged or streaked sidewalls are the result of
foreign objects, such as sand or gravel in the
pulley, or a rough pulley surface.
4. Check for tensile breaks (breaks in the cord
body). Cuts in a belt are usually caused by foreign objects in the pulley, or by prying or forcing
the belt during removal or installation.
5. Check for uneven ribs on serpentine belts. Foreign objects in the pulley will erode the undercord ribs, causing the belt to lose its gripping
power.
6. For EPDM belts, check the belt for material loss,
which causes the belt to seat further down in the
pulley and to ride directly on the pulley tips. See
Fig. 1.
7. For Neoprene belts, check the drive belts for
cracks. Small irregular cracks are usually signs
of an old belt.
8. Inspect the pulleys for excessive play or wobble.
Excessive play or wobble indicates a failure of
the pulley bearing. Check for belt squealing or
squeaking. Replace the bearings as necessary.
NOTE: If it is difficult to distinguish the location
of a supposed bearing noise, place a stethoscope on the component being checked, not the
pulley, to isolate the area from outside interference.
9. Inspect all pulleys for foreign objects, oil, or
grease in the grooves.
Belt Tensioner Inspection
On belts equipped with a spring tensioner, belt tension is automatically adjusted. Check that the tensioner is holding tension on the belt by inserting the
end of a breaker bar in the 1/2-inch square hole on
the forward face of the tensioner, and rotating the
tensioner away from the belt. When the breaker bar
is slowly released, the tensioner should return to its
original position. The tensioner should rotate
smoothly with no binding. If not, see Group 01 of the
122SD and Coronado Workshop Manual for replacement instructions.

or any other damage. If the air cleaner housing
or element is damaged, replace it.
3. Check the inserts at all four assembly fastener
locations (see
Fig. 3). Each insert should pro-
trude from the housing as shown in Fig. 4.
If the head/flange of any of the threaded inserts
is flush with or countersunk into the housing, replace the air cleaner assembly. See Section

NOTICE
Do not use aftermarket air cleaner elements. Aftermarket air cleaner elements may not seal the
housing correctly, which can lead to engine damage and potentially the loss of warranty. When replacing an air cleaner element, use only the part
listed in PartsPro for the serial number of the vehicle.
