The second sight I enjoy greatly as its put in to the most simplest terms; very well done

Be certain to replace the tensioner too. The project will take you six hours or so, be patient and enjoy the process. Be certain to take digital photos as you go and tag what goes where and take notes as to routing of wires and hoses.
Please let me know if this assited you,
Thanks,
