DRAIN AND FILLING OF COOLANT Preceding Work : Removal of skid plate Drain / Filling
1. Loosen the pressure cap of reservoir by 1 notch and removepressure and then loosen the cap. Notice Do not remove radiator cap when coolant is above 90 °C.
2. Open the drain plug and drain the coolant.
Notice Collect the coolant by using the proper bottle.
3. Remove the drain plug(1) and seal(2) of cylinder block and drain the coolant.
4. Replace the seal to new one and tighten the drain plug
Installation Notice
Tightening Torque 30 Nm
5. Tighten the drain plug of the lower radiator.
6. Fill the coolant through coolant reservoir-tank. Notice
A proportion of 50% by volume of water / anticorrosion
must be ensured
7. After engine is running at idle speed, check the level of coolant. If necessary, add enough specified coolant. MAINTENANCE AND REPAIR

Removal & Installation Procedure
1. Remove the O-ring.Check for damage and replace it if necessary.
2. Remove the injector bracket from the injector.
Installation Notice Exactly seat the anti-twist lock into the square groove in
injector.
3. Separate the injector from the fuel distributor. Inspection & Maintenance Inspection of the Injector operation and spray pattern
1. Connect the contact box to the ECU.
2. Connect the shop made test plug to the injector and place it into the tank.
3. Position the ignition switch to ON.
4. Connect the pin 63(+) and 69(-) of the contact box with a test cable.
5. Check the injector spray pattern.
NoticeReplace the injector if the injector spray pattern is abnormal or the fuel doesn't inject.
Injector Resistance Inspection
1. Remove the injector connector.
2. Measure the injector coil resistance using a resistance tester. Notice Replace the injector if the measured values is out of the specified values. Check the connector and wire connectionbetween the ECU and the injector if the measured valuesare normal.
Specified Value 14 - 17

KNOCK SENSOR
Functions Vibration of the engine block is transmitted to the sensor and transferred to the ECU in the form of an alternating voltage signal via a shielded cable. The knock sensor is fastened to the engine block to recognize knocking in all cylinders. TheECU compares the signal and the retards firing point. Removal & Installation Procedure
1. Disconnect the knock sensor connector from the intakemanifold bracket.
2. Unscrew the mounting bolt (M8 X 28) from the knock sensor installed on the cylinder block and remove the knocking
sensor. Installation Notice
3. Installation should follow the removal procedure in the reverse order.
