First of all sorry on my language, English is not my native language.

I am working on Fiat Panda , 1.2 v8, year is 2012.

There are no marker marking/lines that I can use to align the VVT




I have the special tools as well as the tool 1a that you can see on the photo above, but I can not figure out how to align this big wheel(camshaft pulley is its name yes ?) and then insert this tool that you can see on the picture.
As like I said, usually before replacing the belt you would make marks that you can use to align everything in place but this car has no markings at all, no one took the time to use the marker and make some marks.

Can anyone help me figure out how to align this thing ?

The cam shaft wheel does not have a key to the cam shaft ,it fits to cam shaft in any position that is why there are no marks on wheel.

The cam shaft is locked in position using the special tool at opposite end of cam shaft to the wheel.

Marks aren't really that important. You can make your own reference.marks using tipex and use the crankshaft, camshaft, and vvt locking tools BEFORE removing the timing belt.

Just to add. Lock the crankshaft first. It will need to be turned because the locking tool only fits in one exact position.

The thing is, someone already changed the belt, but they messed up, and did not make any marks, so now they brought the car to me because I have the special tools needed.
I was able to use the tools to align and lock everything.

But now I have to use the tool that you see in the photo, marked with 1a

Its supposed to lock the big wheel, I marked it in red here in the photo


How am I supposed to know how to position this big wheel ?

Or am I missing something ?

All the other tools can fit only in one place in one certain position, but this tool marked with 1a can fit between any teeth, so how can I make sure to align big wheel properly ?

The position of the wheel isn't important
The position of the can shafts themselves is what matters
You can't time these engine's from the position of the pulleys(allthrough it is possible is everything is allready perfect but not advised) as they arnt keyed to the shafts

While Ive never done a timing belt myself I do believe you should have a locking tool that fits on to the camshaft
Itself on the opposite side I thing like these

I did our belt and water pump about 2 years ago without the fixing/locking tools and its done 15k perfectly fine since and no need for a proxy relearn.

I think I set the engine at tdc on cylinder 1 and marked the pulleys in some way. I think when the engine is tdc the inlet/exhaust valves of cylinder 4 keep the cam from turning, I'm more used to the 850 engines so I've probably got lucky.

You may find that at tdc cylinder 1 that the valves of cylinder 4 should both be open by the same ammount. You will have to take the carbon cover off to do this.

As said above, the pulley does not set the timing. The timing is set with the crank and camshaft locking tools. Post #6 above shows a link to a pic of the cam locking tool. That places the cam in the correct place.
There is also a crankshaft locking tool, that places the crank with all pistons midway in the cylinders, so the engine is not timed at TDC.
Once the locking tools are in place, the belt can be fitted. The camshaft pulley should be loose at this time, to allow the pulley to be where the belt needs it. The pulley locking tool I think is to prevent the belt taking any strain while the bolt is tightened.

On all the FIRE camshafts I've seen (not lots), the camshaft has a hexagon cast into it, where a large open spanner can be used to hold the camshaft when tightening or loosening the pulley bolt. (I think I remember a 27mm spanner fits)

So you need the crank and cam holding tools. Slacken the pulley bolt. Remove the belt. Set the crank and cam with the tools, then carefully fit the belt. With the belt tensioned, use the pulley locking tool and tighten the pulley bolt, while also holding the camshaft with a spanner. Remove the tools, rotate the engine two full complete turns, and refit the tools to check all is still aligned.

If in the previous "messed up" attempt the VVT pulley to camshaft bolt was loosened then it may now be out of timing by a fraction of a tooth. This is when the 1a tool is needed to reset it. Otherwise the crankshaft and camshaft locking tools should keep everything alligned.
