2012 FF
CAUTION:
• All restraint systems should be disabled before beginning repairs.
• Electronic modules located within 305 mm (12 in.) of any welding should be isolated.
• Protect vehicle from weld spatter damage.
• Vehicle service manual should be referenced for guidelines and warnings.
Service assemblies for body components may be disassembled if utilization of the subcomponents is more
appropriate to the repair or to reduce vehicle disruption. The structural and non­structural metal on the Fiat 500
(FF) may be sectioned in several areas providing the prescribed methods below are adhered to.
The joint should whenever possible be performed in as "flat" an area as possible to simplify the repair. While the joint
may include "holes" and formations, it is suggested they be avoided but where this is not possible, the technician must
ensure that the additional material thickness does not impede installation of fasteners, etc. that the hole exists for.
All dimensions are to be restored to factory specifications prior to full or partial component replacement.
CAUTION: NVH foam should be removed from the weld area, as material may be flammable.
CAUTION: Do not apply any corrosion protection or NVH foam prior to completion of welding, as materials are
flammable.
The described sectioning locations only explain joint location and type. All other welds along the sectioned
portion of the component must be replaced. Squeeze Type Resistance Spot Welding (STRSW) is the method to
be used. If accessibility prevents application of spot welds MIG plug welds are to be used. Welding of structural
panels through 3 or more tiers of panel stack ups will require 9.5 mm. plug welds. Exterior panels should be
installed using 8 mm. plug welds. For further information (Refer to Collision Information ­ Specifications)
When welding is completed apply inner panel rust proofing, such as Mopar Cavity Wax Kit (part #68042969AA), Mopar
Wax Refill (part #68042970AA), or equivalent. Apply to the inner cavity areas in two applications with a 30­minute flash
period between the applications. Pay particular attention to areas which have been welded. Corrosion protection should
always be restored to manufacturer specifications. For further information on Corrosion Protection, (Refer to Collision
Information ­ Standard Procedure).
Finish, sealers, adhesives and silencers should be reapplied or replaced to OEM locations and specifications, (Refer to
Collision Information ­ Material Locations).
