A new nut assembly for hinge and latch attachments on vista vents is now available.
The new nut provides a better appearance as well as better seal against water leaks.
If conditions such as loose hardware and water leaks at the hardware attachments are noted, replace the old nut and bushing assembly with the new nut assembly.
The new nut has an integral seal and therefore no longer requires the use of bushings.
Due to the lower profile and improved appearance, the new nut should be used in all locations (hinges and latches) when service operations on vista vents are performed.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
