MODELS/YEARS 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.)
