Hi All,
I have a rather frustratingly annoying high pitch noise at idle, if you rev the engine it disappears. You can only hear this noise in the cab. I have recently serviced the van and replaced all cam belt and tensioner, aux belt tensioner and ideler...but this seems to have increased the the occurrence of the noise, I am thinking this is possible a power steering pump issue, I have no other problems with the pump but cant think where else it is coming from. Has anyone else had this problem, what are your thoughts?
Thanks in advance.
