General Information
Daimler Trucks North America LLC, on behalf of its Freightliner Trucks Division, is initiating Field Service Campaign
SF503A to modify the vehicles mentioned above.

Work Instructions
Subject: Cascadia 1625 Radiator Tuned Mass Absorbers
Models Affected: Specific Freightliner Cascadias built with a
1625 square inch radiator, manufactured May 28, 2010, through
February 28, 2013.

Radiator Installation Inspection and TMA Installation
1. Check the base label (Form WAR259) for a completion sticker for SF503A indicating this work has been done.
The base label is usually located on the passenger-side door about 12 inches (30 cm) below the door latch.
If a sticker is present, no work is needed. If there is no sticker, proceed with the steps below.
2. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
IMPORTANT: The TMA installation procedure applies only to vehicles with "bow-tie" mounted 1625 sq in radiators.
See Fig. 1. It does not apply to vehicles that have been retrofitted with 1400 sq in radiators with lower isolators
or any other configuration.
3. Inspect the radiator to determine whether a TMA should be installed:
If a TMA is already installed (see Fig. 10), or if the vehicle has been retrofitted with a 1400 sq in radiator
with lower isolators, no further work is needed. Clean a spot on the base label (Form WAR259). Write the
campaign number, SF503A, on a blank gray completion sticker (Form WAR261), to indicate the work has been
completed, and attach it to the base label.
If the vehicles has a "bow-tie" mounted 1625 sq in radiator and no TMA is installed, go to the next step.
4. Remove the front bumper.
5. Remove and discard the lower right-hand radiator baffle. See Fig. 2.
