Technical Cambelt change - Lost the position of the gears?
Yes my mobile mechanic was convinced he didn’t need the locking tool and went ahead. Car went almost into limp mode after, he believed he was a tooth out. Redone and the car wouldn’t start. He then bought the locking kit and done it perfectly. He commented how he now saw that it was nigh on impossible and certainly not confident that it could be done without the risk of messing it up.
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:
https://pmmonline.co.uk/technical/belt-replacement-guide-fiat-500/
So when following these instructions the marks on the belt is not important?

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 fitting instructions you've found are the correct ones too. There is an excellent guide, by Andy Monty, to this in the Grande Punto section too. When looking for it don't click on the "guides" in the blue bar at the top of the page. click om the "Grande Punto" section and look for the hammer with "guides" written under it. Click on that and scroll down to the 1.2 8V EVO 2 Engine Cam Belt Replacement.
It is possible to do the job without the kit but you need to be brave and experienced to get away with it. If you type - Becky's timing belt - into the search bar at the top of the page you'll see several posts I made at the time which may be of help.
The bolts holding the engine mount to the front of the engine are a bit difficult to access but otherwise it's really not a bad one to do. Good luck with it all. Do let us know how you get on.
Kindest regards

Yes you totally ignor the marks on the belt because those marks are not for your engine.
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.

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.
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?
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.
How funny just watched a German YouTube on a Ford ka using belt lines and coloured dots.
I have only turned the engine by the crankshaft bolt (lower). I might have mixed up the lingo before...
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.

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?

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.
The lines on the crankshaft sprocket were fine if you were doing it the Ford way.
The problem is you have no mark on the camshaft sprocket to line up with the belt line.
If you had made your own mark in the correct place on the cam sprocket before removing the old belt you would have been ok.
Problem now is both camshaft and crankshaft sprockets have been wiggled so you must get the special tools to ensure correct relationship between crankshaft and cam shaft.
