Hi dullbird,
Have you tried a squirt of CRC on the belt when the squeek is occuring.I used to worry about all thesqueeks on start up and as engine warming.My mech an experienced landy mech showed me with a coulple of well placed squirts of CRC that the noise was indeed coming from the belt.ie Squirt -non squeel -but returned later till engine was warm.
Don't notice it now as it's a recognised no worrios noise
Cheers,
Mary
