Default 2000 es300 alternator belt tension

What is the recommended alternator belt tension for 2000 es300? It does not have auto belt tensioner.
I put on new belt yesterday and it squealed on start up when cold. So I tightening it some more and and it doesn't make squeal noise any more. Belt is tight... Maybe 1/2 " flex between alt and harmonic balance with 2-3 pounds of pressure. I don't want to damage anything with belt on too tight.
thanks in advance.

You should be able to twist the belt 90 degrees on the longest section of straight belt, but not much more.
