5.4.1 Geral

5.4 Corrosion Prevention 5.4.1 General Avoid drilling into closed frame body members to avoid the risk of corrosion from swarf. If drilling is required, however: • Re-paint metal edges and protect against corrosion after cutting or drilling operations. • Endeavor to remove all swarf from inside the side member and treat to prevent corrosion. • Apply corrosion protection inside and outside of the chassis frame. 5.4.2 Repairing Damaged Paint After cutting or reworking any sheet metal on the vehicle the damaged paint must be repaired. Ensure all materials are compatible with the relevant Ford specifications and maintain the original performance where possible. 5.4.3 Under Body Protection and Material WARNING: Do not over-coat or contaminate surfaces of components such as brakes or catalytic converters. Ensure all materials are compatible with the relevant Ford specifications and maintain the original performance where possible. Some proprietary products affect the original coatings. For specifications of corrosion protection materials, please consult your local National Sales Company representative. 5.4.4 Painting Road Wheels WARNING: Do not paint wheel clamp surfaces in contact with other wheels, brake drum or disc, hub and holes or surface under wheel nuts. Any further treatment in these areas may affect the wheel clamp performance and the vehicle safety. Mask the wheel when changing the color or repairing paint. 5.4.5 Contact Corrosion When using different materials with a different electrochemical potential, ensure that materials are isolated from each other to prevent contact corrosion caused by a potential difference. Use appropriate isolation materials. Where possible, choose materials with low level of electrochemical potential difference. FordRanger 2011.5 Date of Publication: 05/2011
