Corp. Ref. No.: 771209
SUBJECT: AIR CONDITIONING HOSE ROUTINGS
MODELS AFFECTED: 1987 SKYHAWKS WITH THE LL8 2.0L L-4 OHV (VIN CODE 1) ENGINE, AND C60 AIR CONDITIONING
Some 1987 Skyhawks 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 closely to exhaust system components.
If any of these conditions are encountered, the air conditioning hose/pipe routings should be carefully adjusted to achieve the following minimum clearances. Refer to illustration.
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.)
