And this fixed the squeal? Had you replaced the water pump with a different brand to cause the squeal or did it just start happening?

[Salisburytree]

I replaced a tensioner which caused the squeal so I thought, I was then shredding belts so I then put the old tensioner back on and it still squealed. From there iv tried 4 different tensioner. Replaced fan pulley, idler, alternator water pump and vacuum.

Stuck a new belt on the other day and it just falls off after squealing for a minute or two.. Something still isn't right

you've only got the bottom crank pulley to check then.
