ok, i need to put the new timing belt and it is too tight, when i remove the old timing belt i just remove the two tensioner round thing to remove the belt , but when i try to put the new timing belt it is too tight... how to loose the tensioner so i can put the timing belt really easy not to force it? what i did wrong ? or do I need to loose something to put the new timing belt without forcing it?

can you show me in the diagram where is the adjusting nut you are taking about. i just remove the nut in front of the tensioner to remove the old timing belt... i did not adjust any adjusting nut.

thank you, is the nut next to one of the nut of water pump your picture is with the bottom cover of timeing belt.... mine is open already i wish i can find it because i dont remember loosing one when i removed the old timing belt... please be patient with me this is the first time i work on timing belt due to high cost of repair shop thats why i try to do it my self... i work on my car before changing brakes ,starter,and it is first time on timing belt.
