Get a copy of the Haynes workshop manual from a second-hand bookshop or e-bay etc.
Remember the same engine was used on the Cavalier so that manual would do.
I have the Cavalier manual, if you're anywhere near Perth, Scotland, you're welcome to have a look!!
You might be able to get more info at these sites
