2007 Elantra Timing Belt Tensioner
 

Just replaced timing belt on 2007 Elantra at Firestone. Have a suspicion that the belt is overtightened. There is some small additional noise from the belt side when revving the engine. It's very quiet when idling. Is the belt tensioner spring loaded and self adjustable? Had 1997 Geo Prizm with spring loaded tensioner - awesome, no worries of overtightning.
