Okay, I will try and answer. I've never worked on a 3 cylinder Corsa so I don't know what quirks they have. The usual procedure for replacing the cambelt is as follows: Rotate the engine until the crank pulley lines up with the TDC marker - they'll be a cut-out on the pulley. Remove any casing covering the cambelt, especially at the top where it covers the camshaft pulley. Make sure crank pulley still lined up with TDC and check for cutouts on the camshaft pulley. It'll either line up with the cylinder head or a marker on top of the camshaft housing etc. Slacken the cambelt adjuster and remove belt. Make sure all pulleys are clean and then fit new belt. Make sure to keep the long side tight and line up with all the teeth on the crank and camshaft. Tighten adjuster so that belt on long side has about 1/2 inch travel. Ensure crank pulley and camshaft pulley still lined up with marks and then rotate engine a few times. Re-check the tension of the belt. If it's okay then start the engine.
In some instances you may have to remove the alternator belt to gain access. Other cars you may have to remove the engine mounting and jack the engine up.
