CS-144 Generator Replacement

Beginning with the 1998 model year, General Motors stopped releasing internal repair components for the CS-144 Generator.
GM warranty procedures require the replacement of the CS-144 generator. The generator unit repair procedures found in the past model Service Manuals
should not be used.
Use of non-GM repair parts for warranty repairs is not approved or recommended. Therefore, warranty labor claims for CS-144 generator rebuilds in the
field for 1998 and newer vehicles will not be accepted.
Service parts which may be available through GM for past model years, which appear to fit, should not be used. The use of correct parts is essential for
proper performance of the generator.
This policy change was instituted by GM to provide the best service and warranty experience for our customers.
