INSTALLATION
Installation is in the reverse order of removal.
Perform the following :a. Adjust the shift cable.
b. Refill the engine with engine oil.
c. Refill the transaxle with fluid.
d. Refill the radiator with engine coolant.
e. Bleed air from the cooling system with the heater valve open.
f. Clean the battery posts and cable terminals with sandpaper assemble them, then apply grease to prevent
corrosion.
g. Inspect for fuel leakage.
After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for
approximately two seconds and fuel line pressurizes.
Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.

4.Disconnect the ECT(Engine Coolant Temperature) sensor connector.
5. Remove the coolant hose related to the heater hoses and the ECT(Engine Coolant Temperature) system.
6. Remove wiring protector.
7. Remove water temperature control assembly(A) and the gaskets(B).
8.Remove the water pipe(A).
THERMOSTAT
Removal of the thermostat would have an adverse effect, causing a lowering of cooling efficiency. Do not remove
the thermostat, even if the engine tends to overheat.
1. Drain engine coolant so its level is below thermostat.
2. Remove the coolant inlet pitting(A) and the thermostat(B).

3. Install the wiring protector.
4. Connect the heater hose and ECT hose.
5. Connect the ECT sensor connector.
6. Connect the radiator upper and the lower hose(A).
7.Install the air cleaner assembly.
8. Fill with engine coolant.
9. Start engine and check for leaks.
10. Recheck engine coolant level.
THERMOSTAT
1.Place thermostat(B) in coolant inlet pitting(A).
Install the thermostat with the jiggle valve upward.

6.The MICRO 570 will detect the amount of ripple from the charging system to the battery. Excessive ripple usually
means the stator is damaged or that one or more generator diodes have failed.
7.The MICRO 570 will prompt you to turn on accessary loads. It will then test at idle and prompt you to rev the
engine. The analyzer will determine if the charging system can provide enough current for the demands of the
vehicle's electrical system.
When asked to turn of the accessory loads, turn of the blower to high(heater), the high beam beadlights, and
rear defogger. DO NOT use cyclical loads such as air conditioning or wind- shield wipers.
8. After the test, the MICRO 570 will display the idle voltage, load voltage and the state results.

TEST
1.Check to see that the voltmeter reads as the same value as the battery voltage. If the voltmeter reads 0V, and the
open circuit in the wire between alternator "B" terminal and battery ( - ) terminal or poor grounding is suspected.
2. Start the engine and turn on the headlamps.
3. Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500
rpm and read the maximum output current value indicated by the ammeter.
After the engine start up, the charging current quickly drops.
Therefore, the above operation must be done quickly to read the maximum current value correctly.
RESULT
1.The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good
condition, remove the alternator from the vehicle and test it.
Limit value : 70Ë of the rated current
a.The nominal output current value is shown on the nameplate affixed to the alternator body.
b. The output current value changes with the electrical load and the temperature of the alternator itself.
Therefore, the nominal output current may not be obtained. If such is the case, keep the headlamps on the
cause discharge of the battery, or use the lights of another vehicle to increase the electrical load.
The nominal output current may not be obtained if the temperature of the alternator itself or ambient
temperature is too high.
In such a case, reduce the temperature before testing again.
2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the ammeter and voltmeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.
REGULATED VOLTAGE TEST
The purpose of this test is to check that the electronic voltage regulator controls voltage correctly.
PREPARATION
1.Prior to the test, check the following items and correct if necessary.
Check that the battery installed on the vehicle is fully charged. The battery checking method is described in the
section "Battery".
Check the alternator drive belt tension. The belt tension check method is described in the section "Inspect drive
belt".
2. Turn ignition switch to "OFF".
3. Disconnect the battery ground cable.
4. Connect a digital voltmeter between the "B" terminal of the alternator and ground. Connect the (+) lead of the
voltmeter to the "B" terminal of the alternator. Connect the ( - ) lead to good ground or the battery ( - ) terminal.
5. Disconnect the alternator output wire from the alternator "B" terminal.
