Hello, my name is Lee and I have a 1998 GTO SR.
Last week I had a loud(ish) screeching noise coming from the engine bay when driving and when ticking over. I sprayed some WD40 on the Power Steering belt and it went away. This morning the noise came back so to pinpoint the area I sprayed again on the belt but the noise comes back after a couple of seconds. If I spray directly where the belt meets the Power Steering tensioner - it goes away for much longer - no more noise at the moment.
I changed the belt and the P/S tensioner 17 months ago (new parts) and the edges on the belt appears to be a little frayed.
If anyone can help or recommend anything - It will be much appreciated.
