Wasn't looking forward to this but turned out very easy in the end.

1. Place rear on ramps and secure.
2. Remove plastic engine undertray.2a. Remove plastic vapor tank.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.You cannot view this attachment.
3. Compress tensioner spring SLOWLY using large water pump pliers and clamp.
4. Belt drops off.
5. Fit new belt. I used a toyota one. I attached picture of easiest method I found.
After I got it round the crank pulley I could tension the belt with both hands and there was a satisfying"snap" as it went over the edge of the tensioner pulley.
6. Remove tensioner "clamp" and double check with a torch that the belt is over all pulleys correctly.

Satisfying little job, knowing that you've got a fresh belt on that isn't going anywhere anytime soon.

Interesting approach to the tensioner!
