[marinabrid]

hi all again,wife have a little sqeek on engine, 110 tdi 98 year.

its the idler pully i presume, when looking into engine and following the belt anti clockwise from the alternator there be a pully that appears to held by one bolt on a small arm with a 90 degree bend in it that comes out of the engine block.

iif i spray wd on it it does stop sqweeking. it be a plastic pulley with a metal outside.

do i just undo bolt and replace or must i de tension belt first.

thanks

You have to detension the belt, but that is easy. You just put a bar in and pull it. The back of the pulley has a plastic cover on, you pop that off and then it is a nut and bolt job. A replacement is

thanks mm for advice, where do you put the bar to prise it ?

the thing stops sqweeking only when you spray the plastic pulley with wd40

That will be the pully then!

 

You put a pry-bar between the top of the pully and the pully arm and pull!
