Mk6 gtd timing belt

[Davekgtd]

Hello just had my timing belt and water pump replaced now its making a whining noise between 1500-2300-2500 up and back down the revs could this be that its just a new belt or should i take it straight back anybody had one replaced on this model

sounds like it might be too tight, or something else is wrong. you need to take it straight back. who did it , main dealer ?

Ye its been back today they have checked everything and said its all fine just new belt bedding in reassured me its all covered if something went wrong

new belts do not need to bed in and should not whine. it is either too tight or the new water pump is goosed. simple as that. 25 years in the trade and i know things like this..

When the bonnets popped up mate and i get someone to stick some revs on the noise seems to be comming from the rear part of the timming belt housing am i right in thinking this is where the water pump sits

it could be something on the aux belt, but unlikely . chances are they have managed to over tension it or the new pump or a new roller/tensioner is dodgy. it does happen every now and again, but the usual cause of a whine is a belt thats too tight.

[Davekgtd]

Ok they did say they had checked the belt and it wasn't to tight even though when they first listened to it. Thats what they had said it was the belt was to tight and tried to convince me it was fine to drive with the belt over tight

its fine to drive yes, until the extra tightness wears out the water pump bearings, the tensioner bearing or the guides bearings, then the belt snaps or wears itself away.

[Davekgtd]

I way be paranoid but i have a sneaky feeling they haven't replaced the pump and they have just stuck a new belt on and the new belt being nice and tight is causing the old pump pully to whine could this happen ?

yes, that could happen, especially if the old belt was a bit stretched and not tight.

[Davekgtd]
