3B1-8 POWER STEERING (P/S) SYSTEM
POWER STEERING PUMP DRIVE BELT
NOTE:
For J20 Type engine, refer to Section 6H “GENERATOR BELT”.
INSPECTION
Check that belt is free from any damage and properly fitted in pulley
groove.
BELT TENSION CHECK
Check belt tension by measuring how much it deflects when
pushed at intermediate point between pulleys with about 10 kg
(22 lb) force.
Deflection of P/S belt:
6 – 9 mm (0.24 – 0.35 in.) G16 Type engine. . . . . . . . . . . . . . . . .
4 – 7 mm (0.16 – 0.28 in.) H25 Type engine. . . . . . . . . . . . . . . . .
BELT TENSION ADJUSTMENT
[For G16 Type engine]
a) To adjust P/S pump drive belt tension, use adjusting bolt of com-
pressor for A/C equipped vehicles and that of P/S pump for ve-
hicles without A/C.
b) Adjust belt tension to above specification.
c) Then tighten adjusting and mounting bolts to specified torque.
[For J20 Type engine]
To adjust P/S pump drive belt tension, refer to “GENERATOR
BELT” in Section 6H.
[For H25 Type engine]
a) To adjust P/S pump drive belt tension, loosen tension pulley
bolts and turn tension pulley using hexagon wrench.
b) Adjust belt tension to above specification.
Then tighten tension pulley bolts to specified torque.
Tightening Torque
Tension pulley bolts: 25 N
