Where is the tension bolt for the serpentine belt on a Chevy Malibu?

Answer 1

there is no tension bolt ! if the belt is loose it is either a stretched belt or the tensioner is bad. the only bolt on a tensioner is the bolt that goes through center of tensioner to hold it to the engine. no adjustment. good-day ! on the tensioner there are a few marks to tell you if it needs replaced, it should be on the center mark if all is ok. if its on any other mark. replace belt or tensioner if needed. the marks are on the front side of tensioner accross from the center bolt. alt, water pump, etc, are all stationary.
