I have changed both the idler pulley and the tensioner pulley yet the belt continues to squeak. If I put an expensive belt on, it will be quiet for a few weeks but will eventually start squealing too.
This is a 1990 chevy 1500 4x4

Did you replace the whole tensioner or just the pulley? Are there any coolant leaks?
