KNOCKING NOISE FROM ENGINE COMPARTMENT - 1983 CELEBRITYS AND CITATIONS EQUIPPED WITH THM 125C

ALL CHEVROLET DEALERS
Some 1983 Celebritys and Citations may exhibit a knocking noise from under the hood which could be caused by loose torque converter to
flywheel bolts.
Loose torque converter bolts sound much like a bearing knock and will give several raps on a quick acceleration (engine running free).
With the transmission in gear, the noise may or may not appear at idle depending on the idle smoothness.
Check torque converter to flywheel bolts before attempting to repair any bearing type knock.
