2009 Yaris Timing Belt or Chain?

[zoidberg444]

I would imagine in US, Japanese and Euro markets that Toyota have switched to almost entirely interference engines to squeeze 1-2% better fuel economy and emissions out of them. I know the belt driven GR engines (The V6 unit) in the 90's and early 00's were none interference but later versions did away with it.

All the Yaris engines I know of. 1KR, 1SZ, 2SZ, 1NZ, 1ND, 2ZR are all chain driven engines.

Also I thing that all the non-interfere engines were build with collaboration with Yamaha.
