This guide ring is used when securing the drive belt tensioner to the engine. It is placed between the drive belt securing bolt and the bracket, and can be easily lost during tensioner replacement. Be sure to pick up a new guide ring before installing your new tensioner and relieve worry of lost or damaged hardware.

* This part is designed for the TSI engine only. This can easily be found on the engine cover of your 2.0T VW/Audi. It will clearly be stamped TSI or TFSI.
