NOISE, VIBRATION, AND HARSHNESS (NVH) TROUBLESHOOTING
Use the Chart Below to Help You Find the Cause of the Symptom.
EBS00LPX
1. Locate the area where noise occurs.
2. Confirm the type of noise.
3. Specify the operating condition of engine.
4. Check specified noise source.
If necessary, repair or replace these parts.

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00LPY
●Before inspecting the engine, make sure the engine has cooled down; wait approximately 30 minutes
after the engine has been stopped.
●Visually inspect all belts for wear, damage, or cracks on contacting surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the ▼ marked point.
CAUTION:
When measuring belt tension immediately after belt is installed, first set the tension to the standard.
Then, rotate crankshaft for more than two turns in order to eliminate variance in belt deflection
between the pulleys. Re-measure and adjust the tension to the standard.

Tension Adjustment
EBS00LPZ
CAUTION:
●When belt is replaced with a new one, tighten it a little
stronger than current one to accommodate for insufficient
adaptability with pulley grooves.
●When tension of belt being used exceeds “Retightening
limit”, adjust it to value for “Used belt”.
●When installing belt, make sure that it is correctly engaged with pulley groove.
●Keep oil and water away from belt.
●Do not twist or bend belt excessively.
●When adjusting belt, remove snap retainer from adjusting bolt thread (to prevent the retainer from
becoming pinched or missing).
●After adjustment, be sure to install snap retainer to adjusting bolt thread.
NOTE:
Snap retainer can prevent adjusting bolt from dropping due to vibration during driving.
POWER STEERING PUMP AND WATER PUMP BELT
1. Loosen lock nut (A) and power steering pump mounting nut (B).
2. Turn adjusting bolt (C) to adjust. Refer to EM-11, "
Checking
Drive Belts" .
3. Tighten lock nut (A) and power steering pump mounting nut (B)
in this order.
ALTERNATOR AND AIR CONDITIONER COMPRESSOR BELT
1. Remove RH splash cover (with undercover attached).
2. Loosen lock nut (G).
3. Turn adjusting bolt (H) to adjust.
Refer to EM-11, "
Checking Drive Belts" .
4. Tighten lock nut (G).
