11. Place the fitting tool (8) onto the chain link and rivet
the chain pins one by one.
Tightening Torque35-- 40 N∙m (26-- 30 lb-ft)
12. Check the riveting of chain pins and re-- rivet if nec-
essary.
13. Remove the wire.
14. Position the no.1 cylinder at TDC.
In this position, the marking on camshaft / camshaft
bearing cap (arrow) must also be aligned. If the
markings are not aligned, the timing chain must be
re-- set and the injection pump timing has to be set.

DRAIN AND FILLING OF COOLANT
Preceding Work : Removal of skid plate
Drain / Filling
1. Loosen the pressure cap of reservoir by 1 notch and
remove pressure 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 Torque30 N∙m (22 lb-ft)
5. Tighten the drain plug of the lower radiator.
6. Fill the coolant through coolant reservoir -- tank.
Notice
DA proportion of 50% by volume of water / anticor-
rosion must be ensured.
7. After engine is running at idle speed, check the level
of coolant. If necessary, add enough specified cool-
ant.
