All 1.2 500's use the VVT engine.
The 1.2 VVT engine is an interference design and you can cause permanent damage by fitting the timing belt incorrectly.
AFAIK the VVT engine cannot be timed by using timing marks on pulleys; it can only be done using the correct locking tools. Even the experts have been caught out by this - IIRC @typecastboy had a timing belt issue with a mobile mechanic that needed locking tools to resolve.
@typecastboy - do you have any further information on this?
Before proceeding, obtain the correct locking tools, and make absolutely sure you have both the correct parts and the correct instructions for the specific variant of the engine in your car. If you continue to try to improvise a solution, there is a good chance that you will permanently ruin your engine.
I'm not advocating skipping cambelt changes, but I can't help noticing we get at least ten times more posts about cars which have had engine problems following routine cambelt replacement than we get reporting snapped cambelts.
I did this job on my boy's 1.4 8 valve vvt Punto and our own 1.2 8 valve non vvt Panda about 18 months ago. Yes this is the timing tool kit you need - I bought the Neilsen branded kit on ebay for around £40 and it worked just fine.The engine code was stamped on a shiny silverish plate underneath the carpet in the trunk to the left. I have the 169A4000 engine.
This kit should fit:

Ill order it and try to follow the instructions on:

So when following these instructions the marks on the belt is not important?

Yes, and I'd advise not to turn it by the cam pulley bolt (which actually is difficult to do with the design of the VVT pulley anyway) because you will have less control over the crankshaft which will turn too fast so you may bend a valve anyway. You need to have the plugs out and turn it using the crankshaft bolt. Also turn it slowly because if you turn it at any speed the energy stored in the flywheel, due to turning fast, will bend a valve for you anyway. So two complete revolutions of the crankshaft - which will give one turn of the cam of course - done slowly and without any "blocking" should mean you are in the clear to hit the starter motor.You will have to turn your crankshaft anticlockwise to return to where you started because you can no longer turn it clockwise because a piston may be touching a valve.
Turning it back to look like photos you posted and not turning it again until your kit arrives is good plan.
I seem to remember seeing a very good you tube video of a chap - may have been Polish? - doing this belt change on a wee Ford (which uses the same engine) and the coloured lines on the belt were relevant to the Ford application.Yes you totally ignor the marks on the belt because those marks are not for your engine.

I'm just a little worried that the OP has already told us that he has experienced blocking and if the engine was being turned at any speed at all - and he says he was turning it by the camshaft - valve damage may already have been inflicted. Suppose he'll only find out when he tries to run it?
Oh, I just found it (the you tube video) again. It's actually a Ka. Search You Tube for: Fiat/Ford 1.2l Replacing timing belt and water pump. The car is a very light yellow Ka and the chap doing it is wearing a red and grey overall. Somewhere around 16/17 minutes in is where he shows the use of the coloured lines.
Enjoy

Looks to me that Ford mark up the pulleys with coloured marks. I haven't seen any evidence of this on our Panda or my boy's Punto so I think the best thing to do is buy the timing tools. You will get it spot on that way without having to think too much about the deeper technicalities of the operation.This is the video I followed. I couldnt refer to the video due to some rules in this forum. Here is the link:

However he put the engine in TDC which I didnt. The lines on the belt and the sprockets did line up and then I thought it was enough. And as I understand in normal cases with a non VVT engine it would have been enough, or?
