 When belt is replaced with a new one, adjust it
to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
 When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.
 When checking belt deflection or tension immediately af ter installation, first adjust it to the specified
value. Then, after turning crankshaft two turns or mo re, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.
 When installing belt, make sure that it is correctly engaged with pulley grooves.
 Keep engine oil, working fl uid and engine coolant away from belt and pulley grooves.
 Do not twist or bend belt excessively.
ALTERNATOR AND POWER STEERING OIL PUMP BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (A ) and adjust tension by turning
adjusting bolt (B).
 For the specified belt tension, refer to EM-14, "
Checking Drive
Belts".
3. Tighten nut (A).
A/C COMPRESSOR BELT
1. Remove front engine undercover with power tool.
2. Loosen idler pulley lock nut (C) and adjust tension by turning adjusting bolt (D).  For the specified belt tension, refer to EM-14, "
Checking Drive Belts".

When timing chain is not removed/installed, this step is not required.
a. Rotate crankshaft pulley clockwise to align timing mark (grooved line without color) with timing indicator.
b. Make sure that intake and exhaust cam noses on No. 1 cylinder (engine front side of right bank) are located as shown in the fig-
ure.
 If not, turn crankshaft one revolution (360 degrees) and alignas shown in the figure.
NOTE:
When only timing chain (primary) is removed, rocker cover does
not need to be removed. To make sure that No. 1 cylinder is at
its compression TDC, remove front timing chain case first. Then
check mating marks on camshaft sprockets. Refer to EM-65,
"Removal and Installation".
