The timing belt tensioner on my AX has let go. I've got a couple of question before I start attacking it with a spanner:
1. I've got a TU3M engine as fitted to the GT injection, does anyone know if this is the alloy or iron block?
2. The tensioner went as I tried to start the car - is the engine of the non-interference type or is there a chance of valves meeting pistons?
3. Changing the timing belt and tensioner doesn't look too difficult apart form the restricted space - is there anything else I should be aware of? The Haynes is less than clear when it refers to fabricating tools and specialist citroen tools. Do I hang the weight off the bar and tioghten it until the bar is horizontal?
thanks

If the engine has been running with a broken (or slipping) timing belt, I doubt you'll have any fun with that engine ever again.
Before you fork out money for any spares, do a simple check :
remove timing belt, remove spark plugs, then carefully and slowly crank engine by hand.
If it clearly reaches resistance against turning - and HAS BEEN ALLOWED TURNING - then bye-bye engine [xx(]
Otherwise :
Go by your logic and fantasy, when manuals calls out for special tools.
In this case it's widely known, that a timing belt this lenght is just exactly tensioned right, if with normal fingers force, you can twist the belt 90deg at it's longest run.
