Water Pump / Generator Drive Belt Tension
Inspection and Adjustment
S6RW0D1606014
WARNING!
• Disconnect negative cable at battery
before checking and adjusting belt
tension.
• To help avoid danger of being burned, do
not remove radiator cap while engine and
radiator are still hot. Scalding fluid and
steam can be blown out under pressure if
cap is taken off too soon.

1) Inspect belt for cracks, cuts, deformation, wear and
cleanliness. If it is necessary to replace belt, refer to
“Water Pump / Generator Drive Belt Removal and
Installation”.
2) Check belt for tension. Belt is in proper tension when
it deflects the following specification under thumb
pressure (about 100 N (10kgf, 22 lbs.).
If belt tension is out of specification, go to next steps.
Water pump / generator drive belt tension
“a”: 4.5 – 5.5 mm (0.18 – 0.22 in.) as deflection /
100 N (10kgf, 22lbs)
NOTE
When replacing belt with a new one, adjust
belt tension to 4.0 – 4.5 mm (0.16 – 0.18 in.).

3) After loosening generator bracket bolts (2) and pivot
bolt (3), adjust belt tension to specification described
at step 2) by loosening / tightening generator adjust
bolt (1).
4) Tighten generator bracket bolts and pivot bolt as
specified torque.
Tightening torque
Generator bracket bolt (a): 25 N·m (2.5 kgf-m,
18.0 lb-ft)
Generator pivot bolt (b): 50 N·m (5.0 kgf-m, 36.0
lb-ft)5) Check belt tension for specification after turning
crankshaft two rotations clockwise.
6) Tighten generator adjusting bolt (1) as specified
torque.
Tightening torque
Generator adjusting bolt (c): Tighten 7.0 N⋅m
(0.7 kgf-m, 5.0 lb-ft) by the specified procedure.
7) Connect negative cable at battery.
Water Pump / Generator Drive Belt Removal and
Installation

Exhaust System
General Description
Exhaust System DescriptionS6RW0D1B01001
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
Diagnostic Information and Procedures
Exhaust System CheckS6RW0D1B04001
WARNING!
To avoid the danger of being burned, do not touch the exhaust system when the system is hot. Any
service on the exhaust system should be performed when the system is cool.

At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust system
as follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connection, dent and damage.
• If bolts or nuts are loosened, tighten them to specified torque referring to “Exhaust System Components”.
• Check nearby body areas damaged, missing, or mispositioned part, open seam, hole connection or any other
defect which could permit exhaust fumes to seep into vehicle.
• Make sure that exhaust system components have enough clearance from underbody to avoid overheating and
possible damage to vehicle underbody.
• Any defect should be fixed at once.
