Thanks for the input guys. I have since found the correct page in the Nissan service manual which states the indicator should be in-between the two outer marks for the belt to be within it's "possible use range" with a new belt being towards the LHS. I'm just a fan of preventative maintenance that's all

I've recently aquired an 08 350z HR and noticed that my auto-tensioner indicator is towards the RHS of the markings. I started looking around this area as I have a whiring sound I can hear from within the car. From what I've read this means there is more tension on the belt than required. If the belts are too tight is there still adjustment I can make and if it was once set correctly how could it gain tension? The car has 15k miles on the clock.
