Starting car on COLD mornings, cold like 35 and below, the car squeals about a minute after start up.

Sounds like belt. Goes away when car warms up. Fixes? Causes?

Thanks in advance.

I was told it's the tensioner. No idea how true that is just yet, but it's it's spring-based, an easy, cheap fix.

 

That's your power steering belt. There's two bolts on Alternator. One on top and one on bottom that's PITA. Don't strip it like I did. You can put a bolt in the
alternator bracket to use as a leverage point to pry alternator towards radiator. If belt looks frayed or cracked just replace it. Otherwise a tightening should do the trick.

I just "repaired" this issue on my xA as well.

Here are the two belts you can replace-

Amazon.com: Dayco 5040478 Serpentine Belt: Automotive

You may as well change them together since you'll be in there anyway, here is a pic to give you an idea:

 

Tightening the alternator belt is easy. It is the second belt down below, for power steering pump, that is more difficult to get to.
