Replaced Belts, Quick Squeal on Cold Start
I recently had my two belts replaced and now on cold starts there is a quick squeal. Only lasts for a second then it goes away.
Anyone have an opinion on the cause?

A new belt will settle in to the pulley groves and wear in a bit causing some loss of tension. A momentary squeal on a cold start up is a sure confirmation of a loose belt. On a 350Z it’s always the larger alternator belt that squeals. Take it back for an adjustment, or better yet do it yourself.
There are some great DIY write-ups on tensioning the belts on this site. The spec for how tight to make the larger belt is a 4 to 5 mm deflection with a 22 lb pressure mid span between the pulleys.
When I helped my friend tension my car’s belt, I was the 22 lb pusher. What I did was push down on a bathroom scale to calibrate my thumb, and then applied the same push to the belt.
