need some advice, metalic rattle noise like a stone in a can.
« on: April 05, 2012, 07:07:59 pm »


please advise..

noise has been there for a while, nothing is wrong with the car and its driving spot on. just drove to bristol today without a single glitch. decided to record the noise.

i swear iv read something before about a tin can rattle sound.. but looking at the video is that object ( i dont know what it is but its near the belt) shaking in a worrying manner and the cayse for the noise? im getting a mot done In a few weeks but would appreciate advise so i can approach the.mechanic and suggest him having a look at xyz..

thanks in advance!!!

Aux belt tensioner?

I had a similar noise on my wife's old HDi and it was the alternator pulley.

Cambelt tensioner or roller possibly?, mine is making similar noise, like having a  budgie under the bonnet, booked in for cambelt change in 10 days

Slip off the aux belt and turn each accessory that it runs by hand, that will help narrow down the fault.

The bit n the video that is moving around is the tensioner, this has a nut in the centre. Move the tensioner with a spanner to slacken the belt and remove the belt (draw a diagram of its orientation before removal) and then start the engibe again, if the noise has gone it will be one of the components that was being powered by the belt.
