Re: Radiator needed for 5.3L

Well from what I read on those posts, seems belt throwing will happen if the tensioner is worn out. I re-used the belt on my 5.3L swap, and have been seeing black dust on the engine around the belt drive. Also hearing squeaking sometimes when the engine is cold. Guess it's time for a new belt and tensioner.
