Technical Fiat panda Cylinder Head Gasket Replacement and timing questions

[atakan123123]

Hello everyone, thank you for following the topics I opened before. I had a poor idle problem that I couldn't fix.

As the last step, I decided to remove the cylinder head gasket.


The cover gasket is in good condition.
The valves are slightly brown and discolored. While this is being dismantled, a heat resistant valve will be installed.

I have questions about timing. How many degrees should the flywheel be when the crank and cam are in correct timing?

I think these 3 variables are not in exactly the right position. Maybe that was my problem.

Especially the flywheel looked 6 degrees.

There's three different methods of timing on the 1.2
Two types of timing belts and tensioners

Depending on engine number and oil filler cap

Square oil filler up to engine 2533527 uses timing marks and a different type of timing belt


Square oil filler from 2533528 uses this locking tool

Round oil filler, Evo 2 uses this locking tools

One thing I understand is, isn't it enough to adjust just by looking at these two variables?

 

[koalar]

What's the engine number

Should be here

Is the oil filler square or round

[koalar]

No on the engine block

Should be on a bit sticking out

Fiat tells you to lock the crank and the cam, tension the belt and remove the locks. Thus causes the belt to pull the cam 1 tooth out of step.
I marked the cam wheel and cylinder head with white marker then locked crank and cam then added black lines that align to each.
Lock crank, remove cam lock, fit belt one tooth regarded and tension the belt. The Pen marks should align.

If they don’t align you’ll need to loosen the cam pulley retaining bolt, fit locks and finally tension the belt. Nip the bolt but DO NOT go full torque. Finally removed both locks and use a cam pulley holding tool to torque the centre bolt. Refit crank lock and confirm cam is correct.

EDIT - DO NOT loosen or tighten the cam sheel with the alignment lock in place. The wheel has to be back held with a suitable fog tool while the nut is unscrewed or fully torqued up.

Where did you get these photos? Trying really hard to get a workshop manual without dropping cash for it

Yours is an early engine and is timed just by the marks

One thing I understand is, isn't it enough to adjust just by looking at these two variables?

Yes it is enough

When the signs are correct the flywheel shows 6 degrees.

I wonder if this is normal?

 

[koalar]

I don't know, I have never looked at the flywheel

Some instructions online are wrong

It's this mark on the right in the photo

Which normal lines up with the casting, but doesn't have to

Lock the crank and the cam, then you can check the timing marks and add your own with white marker & Sharpie pen.

Wrong engine

These engines already have timing marks and are timed by them

No locking tools used or needed

I installed the cylinder head gasket and adjusted the engine timing.

While removing it, I replaced 2 radiator hoses. I'm refreshed.

The engine mount was very worn. It was quite difficult to find a new one. Its production has ended and it is not available in our country. I had to buy it from an out of town parts dealer for 2-3 times the normal price.


I'm currently waiting for the engine mount to arrive.

I finally finished the car and it ran smoothly.
I ran it parked for a few 30 minute periods.
I used it for about 10 km. There don't seem to be any problems yet.

I supplemented with 3 glasses of water 3 times at different times. I hope it's just filling the gap. And there is no water leakage.


I couldn't place the timing belt cover properly.

I think I tightened the engine mount a little from the top during assembly.
Because even though I want the cover, it doesn't fit properly.


I don't want to lift the engine again and disassemble many parts. I will use it this way for a while during testing.


I don't know if my idle problem has been solved. I will continue to use it.

The upper belt cover appears correctly fitted

I found an old photo. It must be combined with the camshaft sensor. It looks a little lower and more open now.

I'm not sure about this.
