Rattle coming from the front of the motor

[Susan]

They cleaned the pulleys and replaced the belt. The tech said there was some 'contaminant' on the belt.

When I dropped it off they mentioned that some of the belt tensioners were not torqued correctly and that sometimes causes a noise. There is nothing about retorquing (sp?) on my ticket, but would they likely check that when changing the belt? That might be worth checking also.
