Water pump
The water pump is driven by the engine drive belt and supplies
the coolant to each area of the engine.
Coolant reservoir
Thermostat
When the engine coolant
starts to open (fully open at
flow to the radiator to maintain
the engine temperature.
1. OVERVIEW
The coolant system is to keep the engine temperature stable.
2. COMPONENTS

2112-01
Coolant temperature
sensor
Measures the coolant
temperature and sends the result
to the engine ECU.
Radiator
Radiates the heat through fins and cools
down the hot coolant as the coolant
passes through the tube of the radiator
core.PWM fan
Circulates the fresh air forcibly to exchange
heat with the radiator core fin.

3. INSPECTION
1) Alternator
Output Test
Disconnect the cable connected to the B
terminal on the alternator. Connect one
end of the ammeter to the B terminal and
the other end to the cable connected to
the B terminal.
Measure the maximum output value.
(Maintain the engine speed between
2,500 and 3,000 rpm.)
(Turn the headlamp and all the electrical
switches on.) 1.
2.Pass: If the measured current
is 45 A or higher.
Fail: If the measured current is
less than 45 A.
Check the current of the B
terminal. -
-
-
Move the gear selector lever to the neutral
position.
Maintain the engine speed at 2,500 rpm
with the vehicle unloaded.
(Turn all the electrical switches off.) 1.
2.Open circuit: If the measured
current is 5 A or higher. -
Disconnect the negative cable from the
battery.
Remove the B terminal and turn off the
ignition switch.
Measure the resistance between the L
and F terminals with an ohmmeter. 1.
2.
3.Pass: If the measured
resistance is between 3 and
Faulty rotor coil or slip ring: If
the measured resistance is
-
-
Connect the B terminal wiring.
Measure the voltage with the engine
running. 1.
2.
Specification: 12.5V to 14.5V
Faulty IC regulator or field
coil: If the measured voltage
is 14.5V or higher. -
-
Disconnect the negative cable from the battery.
Connect the negative cable again after connecting the ammeter. -
