Whining noise when starting up
Hi there!
I have a 95 968 - runs great. When I start it, hot or cold, it makes this 'whine'. It sounds like a belt or something needs tightening but not sure which. If I start and stop it a few times (running errands for example) it will start sometimes without the noise.
AC compressor and belt replaced few years back. Noise was there before the replacement.
Thanks for any help!

Hey,
Thanks all - apologies for the video. Ill try to capture another however the noise starts at 2 seconds and ends at 3 seconds. Whine / grind maybe!? Hard to find an adjective to suit that noise.

Drifting
an alt will spike a 20-30 amp output to bring the battery back up for a few seconds immediately after starting. check the belt tension and pulley alignment. belts do stretch with time/ozone.
the belt should be as tight as the timing belt. I go with 5mm deflection and then count turns to zero deflection on the turnbuckle. with the belt at zero deflection, tighten the belt further the same number of turns. then tighten the pivot and lock the turnbuckle and end points.
