CAUTION!
Note:
When installing ribbed belt, make sure it is seated correctly on the pulleys. - Align marking on camshaft gear with marking on cylinder head cover.
- Align marking on vibration damper with marking on lower toothed belt

After installing the camshafts, the engine must not be started for
approx. 30 minutes. The hydraulic valve lifters have to settle
(otherwise valves will strike the pistons). After installing the valvetrain and lifters, carefully rotate the
crankshaft by hand at least 2 full revolutions before starting to be
sure that valves do not strike the pistons.
- Install ribbed belt and ribbed belt tensioner Page 13
