I have a question, if the crank pulley has the same diameter as the one that comes origin OEM, whats the thing about changing the belt in the case of the ones that do not have AC? it does not make any sense

I agree. If the belt is still in good condition you can keep using the same belt. I have AC and used my belt for another 60+ thousand miles after my crank pulley install. I just replaced it last week because it was finally starting to crack and wear after 80k miles. It was the original belt that came on the car.

Comments about changing the belt are specific to the installation of the 10% UD pulley, not the CR Lite. In cars without A/C there is not enough swing on the alt bracket to achieve proper belt tension with the 10% UDP installed. Therefor a smaller belt is required.
