just a small edit, changed the alternarnator warning bulb in the dash, same problem extra glowy due to alternator blowing, but now all warning light don't work speedo/temp/petrol/rev counter do work, yes I made sure the big plug in the back was secure, any idea's anyone?

I presume you're talking about tensioning the auxiliary drive belt; well if it's like my Astra then it's automatically tensioned by a spring loaded jockey wheel. In fact there are markers on the tensioning mechanism to indicate whether or not the belt has worn (stretched).

As for your light business, can't understand what you're saying (grammar).

if i got that right,
get a spanner on the spring loaded tensioner, turn it, slide the belt on and slowly release it. job done.
as for the bulbs - check the fuse for the clocks first but if that hasnt gone it could be the bulbs.

no problem mate. just to confirm - it IS a 15mm. best to use a normal spanner with something on it to lever it a bit (they can make you ache if you're holding it for a while while lining the belt up).

Alternator belt tentioner

Got a Quick tip if anyone else is doing this as a newby to the car, it has been mentioned that to replace tha alternator, you need to pull the engine forward, we loosened the brake servo and managed ........ (a very tight fit but it worked) good luck to anyone trying this lol.

No need...

All you need to to do to improve access is to support engine with a jack and remove top left (as you look from the front) engine mount. Take the alternator out the top, not from underneath as the haynes manual says :Cool2:

Hi
easy way to do the tensioner Greasemonkies tip of the week
look at the rear of the tensioner you will see a small hole then look at the movable section when you turn it to release the tension you will see another small hole turn it until they line up and insert a nail this will lock the tension off then when the belt is lined up at your leisure take up the tension remove the nail job done
Cheers

Or just get a helper to line belt whilst you hold the tensioner off, or vice versa :cool:
