Re: 4000csq belt squeeking at start
If the adjuster rack is not loosened along with the alternator bolts,
the teeth can shear off the adjuster pinion. The rack slot does not match
the arc of the pinion bolt as the alternator moves and the entire rack has
to move to compensate. If the rack is not loose, the adjuster pinion binds
against the rack and voila! - no teeth. At least this is how the system on
my '91 200q works - from your description yours sounds similar.
