The role of the windshield is a lot more complex than simply allowing a view of the road ahead. It is considered a structural part of the vehicle as it contributes to the strength of the roof and A-pillars. The windshield helps to manage collision energy and has become an integral part of several advanced safety systems.

It is commonly asked; what is required when replacing a windshield? With this question in mind, we will be presenting a series of articles that highlight some of the requirements from the various OEMs. Let’s see what GM has to say.

The information that we are looking for can be found in vehicle-specific GM body repair manuals. For 2016 model year vehicles:

  • GM identifies that adhesive must meet GM 3651G specifications.
  • It is important to stay within the same product line, do not intermix primers or adhesives.
  • Be sure to refer to the urethane manufacturer’s directions for curing time specifications, and do not use adhesive after its expiration date.
  • Pinch-weld primer is to applied to any exposed painted areas on the pinch-weld flange. Black primer should not be applied to the existing bead of the urethane adhesive on the pinch-weld flange. Primer is to be applied only to nicks, scratches or the primed surfaces.
  • During the installation process, it is important to keep the door glass open until the stationary glass installation is complete. This will help to prevent the sealant from cracking should the doors be opened and closed, causing a pressure change.
  • GM identifies two specific tools:
    • BO-24402-A Glass Sealant Remover (Cold Knife).
    • BO-39032 Stationary Glass Removal Tool, or equivalent in order to remove the window.

GM does have a specific warning for Glass replacement: “Window Retention Warning: When replacing stationary windows, only use a single component adhesive kit, or an adhesive system meeting GM Specifications, to maintain original installation integrity. Failure to use the single component adhesive kit will result in poor retention of the window which may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.”

Per our contact at GM, for vehicles equipped with a forward-facing camera (front view camera) If the windshield was replaced or R&I, the Frontview camera module must be calibrated.
