This is really doing my nut in!
I’ve had a squeak for a while which sounded like one of the auxiliary pulleys, or the belt slipping, so I’ve changed and had changed all the pulleys (though not the tensioner itself)…new belt etc.. now the noise has got worse (it actually almost totally went away for a while).
It only happens when you’ve had a motorway cruise, though there is a bit of a pulley noise when stationary.
It is worst around 2000rpm and seems to go at higher rpm
There seems to be some wear on the new belt.
I initially thought it was the top pulley gone again (I changed that first a year back), so changed that again today and it’s still there after a motorway run.
I’m stumped and quite frustrated with it now, so any thoughts, or particularly anyone who has had this before would be great.
The cambelt has been changed when I got it, and the garage showed me a receipt for the water pump and cambelt kit – though I have always been worried they didn’t do it and I’m on for cambelt failure – so also checked that today and it’s a Gates belt, so deffo changed, but could the sound be the cam belt auxiliary pulley (tensioner?), or the water pump on the way out (no water loss)
