How do intention the above on a new shape 2006? Or more importantly how do I release tension to get belt on before tensioning it back up? Am I missing something obvious?

not sure on the new shape dont you loosten off the alternator and or powersteering pump like the classic?

Nope don't think so. No adjusters on them. Has a separate auromatic tensioner pulley.

Ha. Automatic.

To the left of the crankshaft pulley is the auto tensioner. From memory its a spanner in the nut in the centre and turn clockwise to loosen tension.

Bang on mate thankyou.
