Timing belt condition + Expansion tank relief valve?
Hi! I got my car about 4 years / 50k kms ago; the previous owner changed the TB at my request.
Today, I tried to check the condition of the belt: Only managed to open the top-right cover (maybe the top-left would be easier?) but couldn't take it out without moving the radiator. I took this photo. What do you think about the condition of the belt? (btw, realized that I don't have a 22mm socket so I couldn't turn the engine over --- the plan was to do that. Turned out that I have only 21mm and 23mm).
Timing belt
On a separate note, when I was putting things back together, my arm might have brushed over the expansion tank. Something fell off. I think it was the pressure relief adjustment? I took a drive and it seems not to leak (from the look of it, the upper piece with a square and a cross was part of what's at the center of the "valve").
Anyone knows what it does? Should I glue it back?

From the looks of it your TB is OK. Nothing to worry about. Regarding the other item, I have no idea what it is.

if so, mine is different.

Yes, sir. I think there're two versions, one with radiator cap and one with filler cap on the expansion tank (radiator has no cap).
Because there's no cap on the radiator but only a small hose (2cm outer diameter?) that goes to the radiator, it's harder to fill (air trapped inside easily). It can take weeks to get the final level.
Once I filled too much on a hot day, and that little thing blew some coolant out. I guess it's some kind of pressure relief, and it possibly could be turned with a ratchet or screw driver to adjust.
On the radiator, where the US version has the cap, there's another plastic "screw" like that one, though it only has a square in the middle, not the cross. Both looks to be 1/2".

Here is a picture of my European model and it appears to be the same as yours. I would presume you have broken the top off so if it is screwed down tight itshould not be a problem unless you need to undo it at some time in the future. I would replace the header tank if it was me, you never know what problem it may cause at some point.

Yes, that's it. I could swear I barely touched it.
I've never adjusted it, either. If it leaks, I'll replace the tank. I hope it doesn't.
