SOFT TOP DIFFICULT TO LATCH IN REAR & CLEANING PROCEDURE

Soft Top Difficult To Latch In Rear:

Some 1990-1/2 Allantes may experience a condition of the rear bow difficult to latch. This may be caused by the soft top material being stowed for extended periods of time after being stored when wet. It is extremely important that the soft top be stored only when dry or slight material shrinkage can occur. To correct this condition, raise the soft top and latch in the rear. Leave the top in the up position for at least 24 hours. Hot towels applied to the top or direct sunlight may aid in stretching the material.

Cleaning Of The Soft Top Cover:

The 1990-1/2 Allante soft top cover is made from an SMC composite material with a Soflex paint system. It is VERY important that NO DETERGENTS OR SILICON CHEMICALS be used in the care of the soft top cover. Recommended cleaning procedure is to use lukewarm water ONLY with no detergents. Detergents and silicon chemicals (i.e., Armor All) cause severe streaking of the painted surface. No field repair process is available at this time for the cover.

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.
