Measurement of Mating Surfac
1. Measure the height (H) of the cylinder head(refer to
Service data standard).
2. Check the mating surface of the cylinder head.
3. Mill the sharp edge of the combustion chamber.
4. Re-- measure the height (H) of the cylinder head.
5. Seal the intake and exhaust valves.
6. Measure the dimension (T) between the camshaft
bearing and the valve system(refer to Service data
standard).
7. Mill the cylinder head valve seat(refer to Service data
standard).

DIAGNOSIS
SYSTEM LEAKAGE TEST
Tools Required
124 589 15 21 00 Tester
Test Procedure
1. Loosen the cap a little and release pressure and re-
move the cap.
Notice:For the risk of scalding, cap must not be opened
unless the coolant temperature is below 90°C.
2. Fill coolant up to upper edge (arrow) of reservoir.
3. Connect the special tool to the reservoir filler cap and
apply 1.4 bar of pressure.
Tester 124 589 15 21 00
4. If the pressure on the tester drops, check leakage at
the all coolant hoses and pipes and each connec-
tions. Replace or retighten if necessary.

COOLANT DRAIN AND FILL UP
Draning & Filling up Procedure
1. Loosen the cap a little and release pressure and re-
move the cap.
Notice:For the risk of scalding, the cap must not be
opened unless the coolant temperature is below 90°C.
2. Loosen the radiator lower drain cock and drain the
coolant.
Notice:Collect the coolant by using a proper container.
3. Drain the coolant from the crankcase by inserting a
hose (dia. 14mm) onto the drain bolt on the side of
crankcase (exhaust manifold) and by loosening the
plug.
Notice
DJust loosen the drain plug to drain the coolant and do
not remove the plug completely.
DCollect the coolant by using the proper container.

4. After complete draining of the coolant, remove the
hose connector to drain plug and reinstall the drain
plug.
Installation Notice
Tightening Torque
30 NSm (22 lb-ft)
5. Tighten the radiator lower drain cock.
6. Remove the de-- aeration hose clamp in the water
pump and remove the de-- aeration hose.
7. Fill up the coolant through the coolant reservoir
tank.
Notice
DMatchtheanti--freezeandthewaterratioto50:50.
DSupplement the coolant until the coolant overflows to
the deaeration hose.
8. Insert the de--aeration hose and completely tighten
the clamp.
9. Check the coolant level in the coolant reservoir tank.
10. Warm up(until thermostat is opened) the engine and
recheck the coolant level in the reservoir tank and fill
up the coolant if necessary.
