Subject: ADDITIONAL CANISTER CONTROL VALVE INFORMATION (REF. 82-I-190) - 1982-1983 FIREBIRD WITH 5.0L V-8 4-BBL. ENGINE (VIN CODE H)
If it becomes necessary to replace a canister control valve on a 1982-1983 Firebird equipped with the 5.0L V-8 engine, a new control valve (part number 17075074) should be used.

It was determined that the original control valve (part number 17070627) may display some of the conditions referred to in bulletin 82-I-190.

The new control valve will be available for service by the end of February 1983 and will supersede the original number.



The new canister control valve should not be mounted using the normal mounting provisions, rather it should be suspended from the vacuum harness (see illustration).. The existing mounting bracket should be removed and discarded..
