CERTAIN 2020-2021 MODEL YEAR SUPER DUTY F-350 TO F-550 AMBULANCE AND WRECKER VEHICLES EQUIPPED WITH A 6.7L DIESEL OR 7.3L GAS ENGINE CERTIFICATION LABEL AND FRONT SPRING MISMATCH TO ORDER GUIDE

 

SERVICE PROCEDURE

Dealers are to order a new Safety Certification label and an Incomplete Vehicle Label (not necessary for all vehicles) per Vehicle Identification Number (VIN), from the Special Service Support Center (SSSC) BEFORE scheduling a vehicle for service.

NOTE: It may take several days for label to arrive.

NOTE: All orders will include two labels, and both labels are VIN specific.

2. With label in hand, confirm that the VIN on the respective new label matches the VIN on the vehicle.
See Figure 1.

• If the VIN does not match, contact the SSSC before proceeding with this program.

NOTE: Federal Motor Vehicle Safety Standard (FMVSS) No. 567.4 requires the label be permanently affixed in such a manner that it cannot be removed without destroying or defacing it. Placing one label over another without removing the first would violate this FMVSS standard.

 

NOTE: Laws may vary by state and region. Concealing or misrepresenting the identity of motor vehicle could be a violation of code resulting in a misdemeanor or felony punishable by imprisonment and/or fines.

3. Upfitter: For incomplete vehicles, apply the Incomplete Vehicle (larger) Label to the Incomplete Vehicle book on top of the current label.

Dealer: For complete (ambulance or wrecker) vehicles, destroy the Incomplete Vehicle Label (there should be no incomplete book for built up ambulances or wreckers).

4. Note orientation of the label on the driver side B-pillar.

5. Using a plastic scraper, remove the Safety Certification label. See Figure 2.

NOTICE: Do NOT use a metal scraper tool, this could cause paint damage.

 

6. Using mineral spirits and a suitable clean cloth rag remove excess residue from the labels.
See Figure 3.

 

7. Using a clean cloth and isopropyl alcohol remove any remaining residue left from the mineral spirits.

8. Install the new label in the same location and orientation in which it was removed on the B-Pillar.
See Figure 4.

 

9. Refer to Dealer Bulletin Parts table for corrected spring part numbers.

10. Replace both Right Hand and Left Hand front coil springs. Please follow Workshop Manual procedures in Section 204-01.

IMPORTANT NOTE: Federal law prohibits selling motor vehicle parts or components that are under safety, compliance, or emissions recall. Unless a part is requested to be returned to FordeBay logo, all parts replaced under this FSA must be scrapped in accordance with all applicable local, state and federal environmental protection and hazardous material regulations. Refer to the Parts Retention, Return, & Scrapping section of the FSA dealer bulletin for further information.
