Probably needs a new AC/PAS belt, but worth checking the tensioner pulley. They can get misaligned

As rubber ages it loses some of it's grip and flexibility. Normal for belts a few years old to squeal a bit in sub-zero temperatures. You can tighten a little, which may fix it, put on some belt lube, which will fix it but not forever, or get a new belt fitted, which will also fix it until it too ages and starts to squeal. Common to all cars.

Loosen the tensioner and let it do its thing, shouldnt be buggered at 62,000km. Take the belt off and spin all the pulleys by hand and check for roughness, inc Alt, That way you can turn the belt inside out and check it all the way round for separation, cracks etc

You could Take the belt off and turn it around so it spins the other way. The 14mm nut on the adjuster will be tight. It is very easy to round off, so beware. and the belt has to be tight, with no more than 15mm freeplay on the longest run.

Chuck 'em. The squeal was their final plea.

i need help here,ever since the new belts went on,i have an intermittent rubbing noise when i turn right,sounds like a rubbing noise and then also like a slight knocking noise as well ,my mechanic {mate}had a good look this arvo and we also drove it and of course the noise didnt really appear.HE checked his tools in case something was left in the engine bay,dont know ,but as he said its a bit of a coincidence.Any ideas,i feel like im back in a ford.

Did you move an AC or PAS pipe out of the way to make belt fitment or adjustment easier?

the belt might be touching the intercooler hose aswell.

If the tensioner is out if line, you can look down at it with the engine running and see it not running true with the belt,
