ye will do, but noise sounds, as if coming at side of engine where all the belts and pulleys are. just remembered that when we first looked at the prob. you could look down and see with the aid of torch that the aux belt had moved sideways a notch. thought that might of been prob. but no. did that still same. but we did ask ourselves why it was off a bit. had to change main pulley wheel as well, as there was a 1 inch triangular chuck missing . couldnt find missing bit , looked like it had been like that for the 35,000 miles i've done.
