after the repair.

Drumming noise - occurs Engine vibration excites CARRY OUT the Powertrain/Drivetrain inside the vehicle during the body resonances Mount Neutralizing procedure. idle or high idle, hot or inducing interior noise REFER to: Powertrain/Drivetrain Mount cold. Very low-frequency Neutralizing (303-00 Engine System - drumming is very rpm General Information, General dependent Procedures).

TEST the system for normal operation after the repair.

Engine drumming noise - Powertrain mount(s) CARRY OUT the Powertrain/Drivetrain accompanied by vibration Mount Neutralizing procedure.

REFER to: Powertrain/Drivetrain Mount Neutralizing (303-00 Engine System - General Information, General Procedures). TEST the system for normal operation after the repair.

Rattle - occurs at idle or Powertrain mount(s) CHECK the powertrain mounts for at light acceleration from a damage. INSTALL new mounts as stop necessary. For engine, Refer to the

appropriate section in Group 303 for the procedure. For transaxle, Refer to the appropriate section in Group 307 or Group 308 for the procedure. TEST the system for normal operation after the repair.

Whine/moan type noise - Powertrain mount(s) CHECK the powertrain mounts for pitch increases or damage. INSTALL new mounts as changes with vehicle necessary. For engine, Refer to the speed appropriate section in Group 303 for the

procedure. For transaxle, Refer to the appropriate section in Group 307 or Group 308 for the procedure. TEST the system for normal operation after the repair.

Clunk - occurs when Powertrain mounts CHECK the powertrain mounts for shifting from PARK or damage. INSTALL new mounts as between REVERSE and necessary. For engine, Refer to the DRIVE appropriate section in Group 303 for the

procedure. For transaxle, Refer to the appropriate section in Group 307 or Group 308 for the procedure. TEST the system for normal operation after the repair.

Idle speed is too high CHECK for the correct idle speed. TEST

the system for normal operation after the repair.

Accessory drive bearing Accessory drive idler CARRY OUT the Engine Cold Soak hoot - occurs at idle or or tensioner pulley procedure. high idle in cold bearing is experiencing REFER to: Noise, Vibration and temperatures of stick/slip between ball Harshness (NVH) (100-04 Noise, approximately 4°C (40°F) bearings and the Vibration and Harshness, Diagnosis and or colder at the first start bearing race Testing). of the day PLACE the EngineEAR probe directly on

the idler/ tensioner center post or bolt to verify which bearing is making the noise. INSTALL new parts as necessary. Refer to the appropriate section in Group 303 for the procedure. TEST the system for
