I have this kit to replace the serpentine belt and belt AC on my 2003 Chevy Tahoe, which I've never done before. The quality of the kit taken is quite decent (nothing in it screamed "cheap"). I originally used a 15mm socket and 24" grip on the main idler and the same socket came in handy to loosen the motor shield bolts from the underside. However, I've found that I'm generally much better at all of these tasks already with an adjustable socket wrench (the head can be positioned at different angles, and the handle lengthened). Despite this, I'm still glad I got this set, so by the way that it didn't cost a decent sum and I'm satisfied with the quality.
