Some advice to anyone out there who hasnt got a clue what they are doing when attempting this type of repair :
1. get your digital camera out and take a lot of pics before dismantling any of the valve timing mechanism.
2. If you cant see the manufacturers timing marks, make your own marks on all the gears and corresponding marks on engine.
3. The use of small wooden or plastic wedges behind your camshaft gears will stop them from turning out of alignment when the tensioner is released.
4. After you have replaced the belt check that your marks all line up.
5. Rotate engine at least to full revolutions of the crankshaft by installing the crank pulley bolt and using a socket and ratchet. Dont force anything if it wont turn.
6 Recheck that your marks all line up.
7. If you are happy that everything is correct reassemble engine.

I am not trying to be a smart a## but just offering some good advice as I have done hundreds of timing belt replacements over the last 35 years as a mechanic. Some engines are interference types, get it wrong and you will be very sorry.

Cheers
