Changing Timing belt tensioner

i have Toyota Avensis 2008 T25 (3ZZ-FE 1.6L) and i know i'm in corolla forum but both cars shared this engine ,i'm planning to change timing chain tensioner because it's leaking and i know i can change only the o-ring but i will change the tensioner for prevent maintenance and i saw youtube video for the procedure and after the installation they crank the engine clockwise ONLY while i checked on the service manual says crank the engine counterclockwise like for few degrees at least 10 degree and then turn it over clockwise so i don't know what to do, do like the manual says or just crack it clockwise and it will release itself.
please anyone replaced this tension tell me what to do
