Early V8 Vantages had idler pulleys that had a ‘retaining’ wall on only one side, which eventually allowed the FEAD belt to get misaligned just enough to squeal. This updated version is dual-walled so the belt stays in place, eliminating the squeal and helping to prevent its return.
The updated FEAD belt and idler assembly must be used together or the chirp will continue! Updating the pulley alone will not solve the problem unless this belt is used with it.
