Bulletin No.T 84-83File In Group 6A
Number 63
Date July '84
SUBJECT: HT4100 CAMSHAFT SPECIAL POLICY
MODELS AFFECTED: ALL 1982 AND CERTAIN 1983 CADILLAC VEHICLES EQUIPPED WITH HT4100 ENGINES
Cadillac has determined that all 1982 and certain 1983 vehicles equipped with HT4100 engines could experience grossly deteriorated engine power and severely decreased idle quality. These conditions may be diagnosed as rough idle, lack of power, engine miss, backfire, valve train noise or idle surge, and may be caused by camshaft lobe wear on one or more lobes.
In recognition of this condition, a special policy applicable to all 1982 and certain 1983 Cadillac vehicles equipped with the HT4100 engine is being issued. The special policy will provide coverage on the camshaft, in the event of camshaft wear, for 5 years or 50,000 miles, whichever occurs first, from the date the vehicle was originally placed in service. This will include waiver of the $100 deductible for the Power Protection Plus second year warranty.
This special policy will include the parts and labor required to replace the camshaft.
