I have a 2003 s40 with almost 107K and I believe that Volvo specs 108K as the time to change the timing belt. My question is, are these interference engines where the engine will seize if I don't change it? I'm debating ($$) whether to wait till it dies (if that doesn't make a difference) vs. changing it now.
I have a starter question I'll also throw up separately. This place rules!!

 

It should have been done at 105K per Volvo.
I recommend at 70K. I have seen to many break or actually the pulley blows apart.

Yes they are interference engines.
