A/C HOSE ROUTING MAY RUB THROUGH AT EXHAUST MANIFOLD

1987 FIRENZA MODELS EQUIPPED WITH 2.0L OHV (VIN CODE 1) ENGINES AND AIR CONDITIONING

Some 1987 Firenzas may not have proper clearance between some of the air conditioning hoses/lines and some engine components. This condition can lead to abrasion of air conditioning hoses/lines or melting of hoses if routed too close to exhaust system components.

If any of these conditions are encountered, and replacement of any of the air conditioning hoses/pipes is required, the routing of the hoses/pipes should be carefully adjusted to achieve the following MINIMUM clearances:

A/C muffler to exhaust flange 23.5 mm (approx. 15/16 in.) Suction hose to exhaust manifold 40.0 mm (approx. 1 - 9/16 in.) Discharge line to alternator bracket 30.0 mm (approx. 1 - 3/16 in.)

Refer to Figure 1

Use applicable Labor Time and Operation Numbers.

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.
