AC noise and risk of engine damage

[vxr2010]

Hi a note of caution , i had what appeared to be a grumbling bearing in the ac compressor , it was actually the little plastic pulley/tensioner underneath it and the compressor was ok , the replacement pulley is around 20£ or so , it’s easy to fit as just needs rad fans taking off , if it does fail it can cause a lot of damage as it can cut into the cambelt so just a point of caution
