Coming from behind and below where all the drivebelts are. Could this be my coolant seals dying? I checked all the drivebelts and none of them seem particularly worn, so I don't think it's from any of those.

1991 NA, this would happen when I drive around the block gently, never going past 3000 rpms.

And another question...if my clutch is giving, what signs (other than performance) would there be?

 

oops
