Serpentine belt replacement cost?

Posted by thechucklingturtle@reddit | askcarguys | View on Reddit | 7 comments

Have a mechanic asking me for over $1000 to replace a serpentine belt. 2012 Buick Lacrosse. Am I missing something or is this a gross over pay? Details below:

Remove and replace in-line 4 serpentine belt tensioner: $359

Belt tensioner: $611

Multi-v reinforced belt serpentine belt: $85

Any help is much appreciated!
