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

Inspection & Maintenance Procedure (for MSE)
1. While the ignition switch is in 'OFF' position, remove thewiring connectors (1 and 15) from ignition coil and measure the primary resistance between terminal No.1 and No.15.
2. During engine cranking, measure primary voltage (T1/1) between ECU terminal No. 71 and No. 69.
Notice If out of specified value, replace the ignition coil.
Specified Value
0.9 - 1.6 (20 °C)
Specified Value 200 - 350 V
Notice
Measure remaining cables.
- T1/2 : No. 72 and 69.
- T1/3 : No. 70 and 69.
If out of specified value, check ignition cable and ECU.
3. Using a multi-tester, measure the secondary coil resistance between 5a and 5b.
Specified Value 6 - 8.5 k
