Hello, and thank you for choosing Just Answer!
It seems you have supplied some conflicting information (for vehicles in North America, anyways)..
So to speed up the process, I have included both possibilities.
Here are the instructions on your belt... This is on the 2.4 engine, which comes in the Camry.
The Corolla comes with the 1.8 engine, and here are those instructions.
If you need anything else, just let me know.
