My 2009 Volvo Penta 5.7 Gi -300-J has an automatic serpentine belt tensioner. I need to loosen the serpentine belt to put on a new water pump. How do I loosen the belt? Please help ASAP!!
Would be easier to post pic of your tensioner. There are a few different ones, and they either need a square drive extension or a wrench to release tension
