File in Section: Service Bulletin 08 - Body and Accessories Bulletin No.: 02-08-98-002E Date: February, 2014 INFORMATION Subject: Hem Flange Rust Repair Models: 2014 and Prior GM Passenger Cars and Trucks This bulletin has been revised to add the 2014 model year, update the Repair Procedure section and add Warranty Information. Please discard Corporate Bulletin Number 02-08-98-002D. Important: To ensure proper coating performance, all of the manufacturer’s “Applications Guidelines” MUST be followed. Repair Procedure 1. Remove the affected body panel from the vehicle and place on a clean non marring work surface. 2. Clean the hem flange area with wax and grease remover. 3. Inspect the area for rust perforation or “micro pin holes.” Important: If perforation is present, replace the affected panel. 3706156 In the event that hem flange corrosion becomes a concern on lower door panels, a new tool has been released by Kent Moore, J-46162, which allows for easier opening and closing of the hem flange. This kit includes a left and right hand flange opening tool that is used with an air hammer, and a hem flange closing tool. Using these tools the lower door hem flange can be opened, the rust treated and the hem flange closed without having to refinish the outer door area. A combination of specialized metal coating products, manufactured by Lloyds, have been found to be the most suitable materials to provide corrosion control and protection. Our recommendation is to prep the metal surface using *Lloyd’s Pure Prep™ Metal Surface Preparation P/N 25418, then topcoat with *Lloyds Kryptonite Metal Treatment P/N 36502 Life Long Rust Protection. It is strongly recommended they be applied according to the manufacturer’s procedures. Copyright 2014 General Motors LLC. All Rights Reserved. 3706159 Page 2 February, 2014 3706167 4. Using the appropriate (left or right hand) flange opening tool, open the flange as shown. Bulletin No.: 02-08-98-002E 3706178 If sand blasting is not available, remove the rust using a 3-M Scotch-Brite™Clean and Strip Disc, Part # 07466, abrasive wheel. 3706172 5. Protect the adjacent area with cloth protective (duct) tape. 6. Sand blast the rust area. Ensure all of the rust is removed leaving clean bare metal. 3706185 7. Using *Lloyd’s Pure Prep™ Metal Surface Preparation P/N 25418 (10 fluid ounce bottle) in a spray bottle, saturate the complete flange area with the pre-diluted solution and scrub the area well, rendering a foaming of the Pure Prep.™ This will greatly improve adhesion and corrosion resistance in the repair areas. Bulletin No.: 02-08-98-002E February, 2014 3706190 Page 3 3706205 10. Apply a light coat of *Lloyds Kryptonite Metal Treatment P/N 36502 with a small brush as shown. This first coat should flash in approximately 3-5 minutes. 11. Apply a second coat of Lloyds Kryptonite. 3706196 8. Using a water dampened clean towel, remove any residue and dry the affected area. Dry the repair area completely using an air hose to blow dry the frame. 9. Check the repair area for phosphate treatment by wiping it to see if any corrosion residue can be picked up. Correctly treated areas will not have any residue on the surface. 3706214 12. Using a small tip opening, apply a small bead of seam sealer such as *LORD Fusor® 806HD (beige) = 10.5 oz (310.5 mL) or the equivalent to the open joint area.

Using a squeegee, force the sealer into the open joint area. 3706573 • Make an initial pass with the tool parallel to the door outer panel. Bulletin No.: 02-08-98-002E February, 2014 Page 5 3706594 • Make a second pass with the tool at a 40° angle towards the inner panel to close the flange completely. 3706625 15. Mask the area as shown to create a 10 mm (0.40 in) wide sealer area. 3706635 3706602 16. Apply a bead of *LORD Fusor® 806HD (beige) = 10.5 oz (310.5 mL) or the equivalent, as shown to completely seal the hem flange.
