this video of
1.4L multiair engine already has both locking tools in place
timing belt bit starts at 29:55
he doesn't really explain how he got them on
in these old blurry videos (
part1 and
part 2), the locking tools just slip on, all alignment holes line up perfectly
he puts on the crankshaft locking tool first
and then locks the cam second
which is the reverse sequence of what's in the repair manual
this
guy does the cam lock first, it is probably the best video
not sure why it didn't come up when I searched earlier (maybe as it has Alfa in title, not Fiat)
there's other
alfa videos
this
italian guy explains stuff well
one of these days I'll get the courage to give it another go
