Recall - Air Injection System (AIR) Defect: Overview

88buick01
Model Year 1983

Bulletin No. 83-C-15

File in Group 64

Number 27

Date Jan., '88
SUBJECT: AIR INJECTOR PIPE CORROSION


MODELS AFFECTED: 1983 REGALS AND LESABRES EQUIPPED WITH 3.8L ENGINE (VIN CODE A) AND CALIFORNIA EMISSIONS (NB2)


General Motors has determined that some 1983 Buick Regal and LeSabre models equipped with RPO LD5 3.8L engine and California emissions may be emitting pollutants in excess of California emission standards. This may be attributed to the air injection tube corroding with increased mileage and exposure.

To correct this condition, the AIR injection tube and AIR injection check valve will be inspected and replaced, if required. In addition, the carburetor primary vacuum break is to be inspected for proper operation. When required, the primary vacuum break, if found to be inoperative, will be replaced.
