WarningBefore any work on the structure of a vehicle with on board electric energy (electric vehicle/hybrid vehicle), the vehicle must be isolated by an authorised technician
WarningObserve the safety and cleanliness recommendations
WarningObserve the precautions to be taken for the pre-tensioning components
WarningAny repair work carried out on a vehicle with on board electric energy (electric vehicle/hybrid vehicle) must be carried out by an authorised person
WarningAll of the stripped surfaces must be protected by means of the approved electrolytic rezincing process
WarningThe number of spot welds necessary for the assembly of a new part must be identical to the number of spot welds fixing the original part

Preliminary operations
Deactivate the pyrotechnic systems
Disconnect the ancillaries battery
WarningEither remove or protect those components which are in the repair zone and risk being damaged by the heat or the dust
Remove
- Front wing (repair side)
- Bonnet
- Bonnet hinge (repair side)
WarningIf the vehicle has the Stop and Start system; remove-refit the voltage retention device
Release the wiring harnesses
Location: replacement part

Identification: front wing upper mounting
Composition: front wing upper mounting
| reference | designation | thickness | nature/classification |
|---|---|---|---|
| (1) | front wing upper mounting | 1,76 mm | high strength |
WarningTake into account the difference in thickness of the part when setting the welding station

Preparation: front wing upper mounting
WarningWhen cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection
Prepare the mating edges and protect them using a weldable primer (index "C7")
NoteApply the weld-through primer on the internal faces of the panels to be welded
Cutting out: front wing upper mounting
Cut out the spot welds
Remove the front wing upper mounting (1)
Cleaning and preparation of the body
Prepare the mating edges and protect them using a weldable primer (index "C7")
NoteApply the weld-through primer on the internal faces of the panels to be welded
Adjustment
Position the front wing upper mounting (1)
Check with the gauge
Position the components used for adjustment
Check the fits and clearances
Holds the part in position
Welding
WarningThe number of spot welds necessary for the assembly of a new part must be identical to the number of spot welds fixing the original part
Weld with electric spot welds
Sealing protection
Apply a phosphate-print layer to the zones laid bare
Painting, then spraying of the index "C5" product into the hollow sections in the repair zone
Additional operations
Refit the electrical harnesses and the components removed
Reinitialisation
Reactivate the pyrotechnic systems
WarningPerform the operations that are required following a reconnection of the ancillaries battery
Reconnect the ancillaries battery
