Tensioner is at an angle and seems to the the source some belt noise so I'm planing on replacing. Can't see where the mounting bolts are and how many there are (and no pictures/instructions in Haynes).

I'm assuming it's remove the air filter housing for access, then the belt, after which I should be able to see a couple of bolts securing the tensioner, pull off and replace.

Is it that easy or are there any hidden complications?

Thanks in advance.
