I'm in the process of doing a timing belt change. I am replacing the timing belt tensioner while I'm at it. I need a little clarity on in. The tensioner pulley is just a pulley, correct? The actual tension is applied by the pin it's self when installed - type 3. So when I install the pulley, it should rotate freely and only be limited by the little bracket that restricts it from a full rotation. Is this correct? Also, should I use any type of "locktite" on any of the bolts during the installation of all major components, or feel confident at tightening to the correct torque?
