SHIFT CABLE CONTACTS THE A/C PIPE CAUSING POSSIBLE RUB

Models Affected: 1987-88 6000 WITH 2.5L, 3.1 OR 2.8L ENGINE

Some 1987-88 6000 models with 2.5L (VIN Code R), 3.1L (VIN Code T) and 2.8L (VIN Code W) engines with MD9 3-speed transmission and C60/C67 Air Conditioners have a potential rub through condition of the A/C pipe by the auto-transmission cable. This pipe is part of the A/C hose assembly routed along the left fender rail from evaporator to accumulator. The vibration and engine roll movement of the transaxle may cause the shift cable to rub through the A/C pipe, causing a refrigerant leak and an inoperative A/C system.

This condition may be addressed by using the following service parts and procedure to protect the A/C pipe.

Procedure For 2.5L Engine (VIN Code R)

1. Loosen the clip that holds the A/C pipe to the fender rail, See Figures 1 and 2.

2. Slide the rear rubber protective sleeve forward to the clip, as shown in Figure 2.

3. Retighten the clip to fender rail.

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.
