How does this tensioner kit improve belt system performance?

Replacing a worn tensioner and idler restores correct belt alignment and tension, which reduces belt chatter and premature wear. The pulleys and spring-loaded tensioner maintain consistent pressure on the V-ribbed belt, helping accessories like the alternator and A/C compressor run quietly and reliably.
