SUBJECT:
KNOCKING NOISE FROM ENGINE COMPARTMENT
MODELS AFFECTED: ALL ENGINES
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 mounting bolts before attempting to repair any engine for bearing-type knock.
