HIGH EFFORTS TO RELEASE HOOD LATCH
A properly adjusted hood will be flush with the fenders and front panel at the outboard corners and approximately 1-3 mm (.040-.118") higher than the front panel at the centerline of hood.
Adjusting the hood striker bolt length 43-45 mm (1.7-1.8") as shown in Figure 1, will give the proper height adjustment in most cases. Adjusting the front outboard hood bumpers so the hood is flush with the fender surface will give the proper height adjustment at the fenders. The proper lubrication points are as indicated in Figure 2. Use GM Part Number 1052349 or equivalent when lubricating the latch striker, latch plate components and secondary hood latch pivot.
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.
