Exhaust Manifold - Cracking

Bulletin No. T 84-28
File In Group 6F
Number 4
Date Dec. '83

SUBJECT: EXHAUST MANIFOLD CRACKING

MODELS AFFECTED: 1982 CIMARRON WITH 1.8L L4 ENGINE


Some 1982 Cimarrons may experience a cracked exhaust manifold when subjected to high temperature and high load conditions. To correct this condition, a new exhaust manifold assembly has been released under the old part number (P/N 14018756) which is now available through GMWDD.

Replacement of the new exhaust manifold assembly requires a change in the outer bolt torque specification (#1 and #4 runners). These four bolts should be torqued to 15-20 N-m (11-15 ft. lbs.). This torque change should be noted on page 6A-25 of the 1982 Cimarron Service Information Manual.
