THERMOSTAT OPERATION Operation
1. At warming upValve closes until temperature of coolant reaches to 85 °C.
B. From Radiator
C. From Crankcase
D. To Crankcase
2. At partial opening. Valve opens partially as temperature of coolant is maintained between 85-100 °C.
3. At full opening. Valve opens full as temperature of coolant is more then 100 °C.

COOLING SYSTEM LEAKAGE TEST
Tools Required
124 589 15 21 00 Tester
Test
1. Loosen the pressure cap by 1 notch and remove the capafter. Notice Do not remove radiator cap when coolant is above 90 °C.
2. Add the coolant to the arrow mark of coolant reservoir.
3. Connect the special tool to the injector of reservoir and apply 1.4bar pressure. Tester 124 589 15 21 00
4. If the pressure on the tester drops, check the hose, pipe and leakage and, replace or retighten.

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
