Belt noise after MI pulley?

How many ft lbs is it supposed to be?

There isn't a torque measurement for a belt, but rather a deflection and a tension measurement. They point to check is half way between the alternator and the crank pulley.

Deflection:
New belt 7.0 to 8.5 mm (0.28 to 0.33 in)
Used belt 11 to 13 mm (0.43 to 0.51 in)

Tension:
New belt 539 to 637 N (55 to 65 kg, 121 to 143 ld)
Used belt 245 to 392 N (25 to 40 kg, 55 to 88 ld)

Yeah it's funny I called my service dept to ask them if they can measure the deflection for me and they said there's no way to measure it. They also said that because there's no tensioner that I wouldn't need to worry, it will tighten itself. I seriously wonder if I should be letting these people do my oil changes, even if it is free.
