There's nothing whatsoever to fear now with the aux belt and cambelt

The cambelt tensioner is what I'd describe as a semi-auto. Setting it is foolproof and there's no guesswork involved at all, unlike the TU (and later XU) eccentrics.
In fact, potentially the most difficult part of the job is cracking the crank pulley bolt loose. If it puts up a fight, use the starter - never fails 8)
Replace the waterpump. Funny things are waterpumps. They get jealous of a new cambelt and show their displeasure by failing two weeks later...
