Isn't there a note in the service manual that they need to be changed at 120K km/5 years
or every 4 years in a cold climate?

It says to replace toothed timing drive belt at 63.000 miles (101.000 km) or every 4 years for heavy duty use - cold climate.
Done mine after 4 years at only 25.000 miles (40.000 km). I used to change cambelts in other Alfas at around 40.000 miles (60.000-70.000 km)

Holy crap, I'm at 98.000km... shocked! I already bought all the parts and locking tools for the cambelt replacement - I tought I'd just wait until 105.000km as specced in the manual, but it'll be a good job for the weekend.

Well the timing belt drive is essentially the same as on the twin spark engines which had to be
replaced every 60.000 km.!
On a Giulietta 1750 TBi it's specify that the cam belt needs to be inspected at 70.000 km service interval.
The pre tensioning of the belt tensioner slowly diminish to zero and then it's time to
replace. Elongated driving results in ripped teeth as the belt becomes too lose.

May be a good idea to change the belt at a shorter interval, and maybe make it public on the forum so that others do the same.

Car manufacturers tend to over estimate change intervals to make the cars servicing costs lower.

I still prefer belts to chains personally. I can change a belt myself, but chains are a lot more difficult.

Cambelt service on a cambelt driven engine at intervals of 100+ km is complete nonsense in my opinion.

This is the most important piece in the engine, moreover it is relatively cheap and I wouldn't even think driving more than 60 000 km or 3 years without changing everything.

What happened in this situation is normal. In Belarus you have rough climate, given the conditions and time nothing unusual happened.

I gave seen a belt go on my V6 and I'd advise always changing early. False economy hanging back and it lets you sleep better at night. Always change the lot - not just the belt.
