Body/Frame - Usage Of Heat For Repair
NUMBER: 31-001-11
GROUP: Collision Bulletin
DATE: Approval Pending
SUBJECT:
Use of Heat To Straighten Damaged Components
OVERVIEW:
This bulletin involves Chrysler Group LLC position with regard to use of heat during repair.
DISCUSSION:
Chrysler Group LLC Service Engineering's position on the use of heat during collision repair is as follows:
^ Any damaged body panel or frame component, which is to be repaired, must be repaired using the "cold straightening" method. No heat may be
used during the straightening process. This "no heat" recommendation is due to the extensive use of high-strength and advanced high-strength
steels in Chrysler Group LLC vehicles. High-strength materials can be substantially and negatively affected from heat input which will not be
obviously known to the repairer or consumer. Additionally, application of heat will alter or destroy material coatings utilized for corrosion
protection and which may not be restorable. Ignoring these recommendations may lead to serious compromises in the ability to protect occupants
in a future collision event, reduce the engineered qualities and attributes, or decrease the durability and reliability of the vehicle.
^ During rough straightening prior to replacement, damaged panels or frame components may be heated to assist in body/frame realignment. This
application of heat, if absolutely necessary, must be constrained to the parts which will be replaced and not allowed to affect any other
components.
