Tensioner or Idler pulley

[heathaurion]

Hey all,

My '09 Aurion started a loud squealing / slight rattling noise today.  The mechanic says it's either the idler or tensioner pulley. With pressure on the pulleys using a spanner on the bolt heads, the noise went away.  

Anyhow .... has this happened to anyone else and is this a common aurion fault?

cheers all- Heath

Hey just wondering did you get this sorted ? Mine is doing the same and looking to take it to Toyota to look at it .

Cheers

One likely source of the noise, says Toyota, is a worn No. 2 idler pulley. Replacing it with a more rugged design (Part No. 16604-0P011) and adding an extra pulley cover plate (Part No. 16649-31020) should silence the noise in short order.
