^^ Agree with what Welshpug said. It's a toothed belt, not an aux belt. It needs some tension but not a stupid amount. The Peugeot manual refers to a Seem meter to measure tension but no such thing seems to exist outside of a Peugeot workshop so above rule of thumb is what most people use. (Some say make sure you can't twist the belt more than 90 degrees max on its longest run, and they presumably mean when you're putting some effort in to it).
