Belt tensioner question

It looks like the drive belt tensioner in my 1997 3.1 liter will have to be replaced soon. Is the bolt a left handed thread type? Thanks.

Std thread.

Thanks

Welcome to AF. Ok, you jumped in on the middle of a 2 year thread, you need to start a new one, see the thread starter button in the main forum page, second do you have spark and fuel pressure, a belt tensioner will not cause a no start. BTW, year and engine are required!
