Suzuki Grand Vitara JB627. Manual - part 118

1J-13 Charging System:

Rectifier
Positive rectifier

1) Using an ohmmeter, connect one tester probe to the

“B” terminal (1) and the other to each rectifier
terminal (2).

2) Reverse the polarity of the tester probes and repeat

Step 1).

3) Check that one shows continuity and the other

shows no continuity. If there is continuity, replace the
rectifier.

Negative rectifier

1) Using an ohmmeter, connect one tester probe to

negative terminal (1) and the other to each rectifier
terminal (2).

2) Reverse the polarity of the tester probes and repeat

Step 1).

3) Check that one shows continuity and the other

shows no continuity. If there is continuity, replace the
rectifier.

Bearing
• Check that drive and bearing is not rough or worn.

• Check that end housing bearing is not rough or worn.

Water Pump and Generator Drive Belt
Inspection and Adjustment

S6JB0B1A06007

1) Disconnect negative cable at battery.
2) Inspect belt for cracks, cuts, deformation, wear and

cleanliness. If it is necessary to replace belt, refer to
“Water Pump and Generator Drive Belt Removal and
Installation”.

3) Check belt for tension. Belt is in proper tension when

it deflects the following specification under thumb
pressure (about 10 kg or 22 lb.).

Water pump / generator drive belt tension “a”
Existing belt: 9.0 – 10.0 mm (0.35 – 0.39 in.) as
deflection / 10 kg (22 lbs)
New belt: 7.5 – 8.5 mm (0.29 – 0.33 in.)as
deflection / 10 kg (22 lbs)

4) If belt is too tight or too loose, adjust it to proper

tension as follows.
a) Loosen adjusting bolt (2) and remove tension

pulley bolt (1). And then turn tension pulley (3)
using hexagon wrench (4) as shown.

b) Adjust belt tension to specification, and then

tighten adjusting bolt (2) and tension pulley bolt
(1) to specified torque.

Tightening torque
Tension pulley bolt (a): 25 N·m (2.5 kgf-m,
18.0 lb-ft)
Tension pulley adjusting bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft)

Water Pump and Generator Drive Belt Removal
and Installation

S6JB0B1A06008

Removal

1) Disconnect negative cable at battery.
2) Loosen tension pulley bolt (1) and tension pulley

adjusting bolt (2).

3) Remove Water Pump and Generator Drive Belt (3).

Installation
Reverse removal procedure noting the following
instruction.
• Adjust belt tension referring to “Water Pump and

Generator Drive Belt Inspection and Adjustment”.

• Tighten all fasteners to specified torque.

Tightening torque
Tension pulley bolt (a): 25 N·m (2.5 kgf-m, 18.0 lb-ft)
Tension pulley adjusting bolt (b): 25 N·m (2.5 kgf-
m, 18.0 lb-ft)

Precautions

Exhaust System Caution

S6JB0B1B00001

NOTE
Be sure to use UNLEADED FUEL for the catalytic converter equipped vehicle. Use of LEADED FUEL
will affect performance of the catalytic converter adversely to a great extent.

General Description

Exhaust System Description

S6JB0B1B01001

The exhaust system of the vehicle consists of the exhaust manifold (with Warm Up Three-Way Catalytic Convertor,
WU-TWC), exhaust No.1 pipe, exhaust No.2 pipe (with Three-Way Catalytic Converter, TWC), muffler, seal, gasket,
etc. The three way catalytic converter is an emission control device added to the exhaust system to lower the level of
Hydrocarbon (HC), Carbon Monoxide (CO) and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.

Diagnostic Information and Procedures

Exhaust System Check

S6JB0B1B04001

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. Refer to “Exhaust System Components”.

• Check under neath body for damaged, missing, 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 passenger compartment carpet.

• Any defect should be fixed at once.
