1. Before fitting the timing belt, make sure that
the camshafts are timed and secured using
tools 1860985000 and that the pistons are
aligned checking the position of the pins for
tool 1860992000 as described previously.
Then fit the timing drive belt, following the
order given below:
1. Crankshaft drive gear
2. Water pump gear
3. Timing drive pulley
