    Hi all, Today I have replaced idler and tensioner pulleys. Given it was my first DIY it went reasonably smooth. Job completed in about 2 hours. When I started the car from cold it seemed to be misfiring and rpm was at about 900 as opposed to the usual 1100 when cold. After 20 seconds engine...

    As in the subject - most DIYs do it though I can't see why it's needed and therefore would try to get away without doing it

    Hi Having a minor squealing on cold start up which quickly goes away when the cars warmed up, reading these forums suggest it will be the tensioner pulley bearing dried up although the belt is old, probably original as the car is a low 30k miles and I've only just bought it. Think I will have...

    Hi This is my first post and im in the process of diagnosing a whining noise coming from my engine. I think i have narrowed it down to the idler pulley on the belt tensioner. What i would like to know is are both the idler pulleys for the belt system the same? and is this the correct one of the...

    I think my new belts have put the old pulleys under more stress and I'm fairly certain one of them is making a noise. I assume the idler pulley can just be un-bolted? Can the pulleys on the tensioners be replaced or do you need the whole unit? (talking both the drive belt tensioner and the air...
