Thermostat
When the engine coolant
reaches 90℃, the thermostat
starts to open (fully open at
100℃) and lets the coolant
flow to the radiator to
maintain the engine
temperature.
Water pump
The water pump is driven by the engine drive belt and
supplies the coolant to each area of the engine.
Coolant reservoir
Long life coolant is used.

is between 3 and 6 Ω.
Faulty rotor coil or slip ring: If the
measured resistance is less than
3 Ω or greater than 6 Ω. -
-
Connect the B terminal wiring.
Measure the voltage with the engine
running. 1.
2.Specification: 12.5 V to 14.5 V
Faulty IC regulator or field coil: If
the measured voltage is 14.5 V
or higher. -

3) Checking Battery

09-71451-01
(1) Checking
Using battery tester ▶
PASS (11.0 V or more): Explain to the customer that the battery is reusable.
Need to be charged (9.0 to 11.0 V): Charge the battery with a charger and reinstall it. Explain it
to the customer.
Need to be replaced (9.0 V or more): The battery should be replaced due to overdischarging. -
-
-
(2) How to use battery tester
How it works and How to use it ▶
Determine battery capacity by fixing current
(load capacity) and time and varying
voltage.
Determine battery capacity based on the
amount of voltage drop when discharging a
fixed load capacity (120 A) for 5 seconds.
Connect the tester to the battery and read
the display while applying a load for 5
seconds. -
-
-
How to read display ▶
Red area (①): overdischarge or faulty
battery
Yellow area (②): Need to be charged (using
a vehicle alternator and a battery charger)
Green area (③): Normal
Red area on the left-hand side of OK (④):
Impossible to charge with an alternator
Green area with OK (⑤): Normally charged
Red area on the right-hand side of OK (⑥):
Overcharged by an alternator태 -

(3) Starting with jumper cable
If the battery is weak or terminated, the battery from another vehicle can be used with jumper
cables to start the engine.
Connecting order ▶
The positive (+) terminal of the discharged battery
The positive (+) terminal of the booster battery
The negative (-) terminal of the booster battery
Connect one end of the other jumper cable to the body of the discharged vehicle, such as the
engine block or a front towing hook. 1.
2.
3.
4.
Starting ▶
Prepare a set of jumper cables.
Place another vehicle that has the same 12 V of power near to the discharged vehicle.
Switch off all electrical accessories for the discharged vehicle.
Apply the parking brake and shift the transaxle to the P position (automatic transaxle) or neutral
(N) position (manual transaxle).
Connect the jumper cables.
Try to start the discharged vehicle while accelerating the engine rpm in the booster vehicle.
Attempt to start the engine with the discharged battery.
After starting the engine, carefully disconnect the jumper cables in the reverse sequence of
connection. 1.

If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a
malfunction in the charge system including the battery. Therefore, carrying out the system check
is needed.
(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the
battery cables with the ignition key turned to ON or ACC position, several electric units can be
damaged due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted
with soapy water. -

Alternator
The alternator charges the battery and
supplies power to each electric unit by
converting the mechanical energy to the
electrical energy.
1. SYSTEM DESCRIPTION
1) Overview
The charge system is designed to supply electrical energy to the vehicle while driving, and
supplies a constant direct current voltage by converting mechanical rotational movement to
electrical energy.
The voltage regulator on the back of the alternator controls the generated voltage in all rotating
ranges and adjusts the system voltage according to the electric load and ambient temperature
change.
2) System Layout (Locations)
Battery
It converts the chemical energy to the
electrical energy and supplies power to
the corresponding electric units when
starting the engine.
