Which engine was that from? It looks very similar to one I changed.
I changed the pulley on the Xsara (HDi engine) four years ago. We had been on a short touring holiday within a holiday in August starting and finishing in France. We went through Andorra, down Spain to Gibraltar and back in seven days.
I had noticed a slight noise when coming back through Andorra but by the time we got to Montpellier it quite noticeable. The noise went away (!) when I turned the A/C off so we continued slowly on using ordinary roads. Unfortunately by the time we got to Nimes even that didn't work We took the final forty five miles quite gently indeed.
Back at base we were joined by some friends who were able to run me into Orange where I was able to buy a new pulley. Prices of car spares in France are much greater than in the UK and it was nearly twice what I would have paid normally.
However, needs must. Back at home I went to work on the grass surface and in a surprisingly short time had changed the pulley. My friends were very impressed as they imbibed wine at the outside table as I worked!
