VISTA VENT HARDWARE NUT W/INTEGRAL SEAL

MODELS AFFECTED: 1982 THROUGH 1986 CIMARRONS WITH VISTA-VENT OPTION (AD3)

Some Cimarrons equipped with a Vista-Vent may experience a water leak condition at the hinge and/or latch attachments. This condition may be caused by poor sealing of the nut and bushing assemblies. To correct this condition a new nut has been released (P/N 20664430). This nut has an integral seal and does not require the use of the bushing (refer to Figure 1).

Whenever service of one of the old style nuts is required, all of the nuts must be replaced with a new style nut due to its lower profile and different appearance.

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.
