SUBJECT:
EXHAUST SYSTEM RATTLE (INSTALL WASHER TO TIGHTEN BELLY BAND AROUND MUFFLER)

MODELS AFFECTED:
1989 SKYLARKS


Customers may comment about a rattle type noise coming from the rear of the vehicle. This noise may be caused by the muffler strap or belly band, not being sufficiently tight around the muffler, which can result in a rattle between the muffler and belly band.





This condition can be corrected by installing washer, part number 14034623, as shown in Figure 1, and tightening to 16 N-m (12 lbs.ft.). Part is currently available from GMSPO.

IMPORTANT:
The belly band must be properly positioned between the locating dimples on the muffler.
