Engine Compartment - Knocking Noise

Number 83-T-32 Section 7 Date 05/83
Subject: KNOCKING NOISE FROM ENGINE COMPARTMENT - 1983 6000 VEHICLES WITH 2.5L L-4 AND 2.8L V-6 ENGNES
Some 1983 6000 vehicles 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 bearingtype knock.
