The hood, trunk lid, doors and front fenders are bolt-on and can be replaced. When installing body elements, it is necessary to maintain a uniform gap along the line of their interface, because otherwise, door knocking occurs or increased wind resistance occurs during movement. The gap must have the same value along the perimeter of the fit of the body elements. Deviations of the gap width are allowed no more than 1 mm.
Caution: If any electrical work is to be carried out as part of the body work, the negative cable must be disconnected (-) battery. To do this, you need to familiarize yourself with the materials of the Section Replacing the battery. Even disconnecting an electrical wire from any outlet should be considered as work on electrical equipment.
Warning: Many lids and trims are clip-on. Damaged or missing clamps must be replaced. Removal and installation of expanding and retaining clips are discussed in the appropriate section.
Safety measures during body work
When repairing the body, spot welding should be used. Only if it is impossible to bring electrodes to the place of welding, welding in an inert gas environment should be used.
- When carrying out welding work or any other work involving the formation of sparks, be sure to disconnect the battery (positive and negative cables) and carefully insulate both terminals (-) And (+). When working near the battery, it must be removed.
Caution: Removing the battery erases data from the electronic memory units, in particular, the radio code. Without a code, the radio can only be switched on by its manufacturer or workshop. Read the notes in Section Replacing the battery.
- Models with air conditioning: It is not allowed to perform welding and soldering with soft or hard solders of air conditioner elements filled with refrigerant. This also applies to the production of welding and soldering of vehicle elements, if this can lead to heating of the air conditioning elements.
- When welding galvanized sheets, toxic zinc oxide is formed. Therefore, it is necessary to ensure good ventilation of the workplace.
- Increase the welding current by 10%, maximum 30%.
- Use hard copper electrodes with high heat resistance (above + 400°С).
- Clean the electrodes frequently and grind them down to a contact surface diameter of 4 mm.
- Increase the pressure on the electrode.
- Increase welding time. The time is correct if the welding points are placed without spatter.
- Do not open the cooling circuit of the air conditioner, as refrigerant can cause frostbite if it comes into contact with the skin.
- In case of accidental skin contact with refrigerant, rinse the affected area with cold water for at least 15 minutes. The refrigerant evaporates at outside temperature. The refrigerant is colorless, odorless and heavier than air. Since the presence of refrigerant is not felt, there is a danger of suffocation in the area of \u200b\u200bthe underbody of the vehicle and in the inspection hole.
Drying paintwork: When carrying out painting work during the repair process, drying in ovens should not be carried out at temperatures above + 70°C. Otherwise, the vehicle electronics may be damaged. In addition, the pressure in the air conditioner may increase, which will lead to the destruction of the system.
Removing the PVC protective coating under the car: To protect against corrosion, a polyvinyl chloride protective coating is applied to the bottom of the car and wheel arches. The protective coating is removed with a rotating steel brush or hot air up to + 180°C using a spatula. When the PVC coating is heated to temperatures above 180°C, a chemical reaction occurs and hydrochloric acid is formed, which contributes to active corrosion, in addition, harmful vapors are formed.
