Has any of u change chain tensioner yourself. how hard is it to do? what need's to be watch out? as i am thinking of doing it myself and when i am looking at the manual, it just show a few steps and its done. is it that simple??
What kind of noise does it make when it is worn or needs changing? Iv got a small noose recently, like a whine when you have a loose cam belt but not that loud, only does it when it's warm?
That'll be the auxiliary belt not the chain (at least I've never heard a metal chain whine... ). As a matter of precaution should change your aux belt, it leaves quite a mess if it goes...
