Subject:
EXHAUST HANGER "O-RING" UNHOOKING
Model and Year:
1990-91 CORSICA, BERETTA
A condition may exist on some 1990-91 Corsica/Beretta vehicles where the exhaust hanger "O-rings" may become repeatedly unhooked from their
retainers. This may cause more than normal looseness in the system and may cause underbody noise comments from the owner.
A new design exhaust hanger "O-ring" has been released to correct this condition. The new part number is 10056770.
Parts are expected to be available on April 8, 1991. Until then, normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP
orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part
will be shipped premium transportation at dealer's expense. All other order types will be cancelled as incorrectly ordered while the 400 control is in
place. Use current warranty labor code and time allowance.
