Simon, Just tried the car over a few miles with aircon on. The cab was getting cooler, proving your point. It's not as cold as I would have liked, but I only took it a couple of miles and it's a hot day so probably needs more time to clear the cabin.
I kept it running on the drive and coudln't hear the noise with air con still switched on. It is over a year ago since I used the aircon and noticed the noise, so maybe I need a longer run for it to kick in again.
If it is the Coley Pully, would it be advisable to change the water pump at the same time?
I'm in Bedford, so if you know anyone who would take it on, I'd be grateful.
Regards Larry
