![]() Does anyone know if the idler pulley is a left or right handed thread? Is it clockwise to undo?
I know the tensioner pulley is clockwise to undo (edit. no it isn't) but I'd like to make sure about the idler before I start getting heavy with it.

![]() I don't know, as I have never worked on one, but I can't see any reason for it to be a left hand threaded bolt.
The tensioner pulley needs to be left handed only so it doesn't undo when you take the tension off the belt. |

![]() Thanks Mike, I thought it might have something to do with the direction of rotation of the pulley. I'll find out at the weekend and post up.

![]() I mistakenly thought that there was just a tensioner pulley so I only ordered that. This thread made me investigate further and I bought an idler too which is probably what’s making the noise on my car.
Probably too late for you but Mister Auto do the INA one for just under £30. |

just to clarify:- the idler pulley bolt is a right hand thread - and the tensioner pulley bolt is a right hand thread.
