CAUTION: Never expose the bumper surface to excessive heat. This may cause the bumper to warp. When collecting exhaust gases in a workshop, never connect a metal collector to the exhaust pipe, because.
CAUTION: The generated heat may damage the bumper. Any attempt to cold straighten brackets with a highly curved profile can lead to weld failure (in the presence of), and can also cause cracks in bent elements. When applying heat to a particular element, always use pencils with a temperature indicator.
CAUTION: Never heat elements to temperatures in excess of 670°Do not attempt to correct any major displacement in a single operation such as "push-pull". This may cause structural damage.
To align or straighten the body, take two diagonally opposite measurements between the A-pillars, B-pillars and C-pillars. Take measurements between reference points, such as fold lines or welds, that are placed diagonally opposite each other on the two posts you are measuring between. Because all measurements should be carried out from open metal surfaces, remove from the locations "base points" all trim elements or chassis elements. See Section 501-05 for more information.
2. Align each section proportionally to obtain the correct measurements. If body alignment does not inspire confidence, refer to figure "Underbody dimensions".
3. Due to the design and assembly of a car with a unibody, when performing any actions to adjust the design of the lower body (bottoms) it is important to control the design of the upper body.
4. Evenly straighten weakly damaged areas before taking measurements for straightening the unibody. To avoid breaking the glass, remove it. See Section 501-11 for more information. In severe cases, it may be necessary to remove or cut reinforcement brackets and other internal structural elements to restore the shape of the body or pillars without causing increased internal stress.
5. In case of large or sharp bends, it may be necessary to use heat. Never heat the elements to temperatures exceeding 670°C. Always use pencils with a temperature indicator when applying heat to any element.
