Just looking at my older threads and realise I’ve not updated a few…

I replaced the belt the other weekend. I removed a few pulleys for inspection (all looked fine) but cleaned them while they were out anyways.
Everything has been put back together and I have a squeal free engine again! No more embarrassing looks from people as I leave my street!  Currently driving: 2012 L322 SE Overfinch 4.4 tdv8

put some few drops of water on belt during engine run. If will be less noise then belt or dirty pullei if bo change then one of bearings.

Mine’s been quiet for 4 months since the tensioner and belt were replaced. Reckon it was a combination of weak tensioner and contaminated belt as both were replaced 10months previously. 2012 TDV8 Vogue (L322)
