off completely or off to install a cam gear?
using a 10mm wrench loosen the tensioner. then there are two pins, front and rear. use a pick tool to loosen the tensioner even more with the front clip.
warning, it's FUN to put back on.
remove serpentine belt cover (two 10mm bolts)
15mm wrench for the tensioner
remove serpentine belt. remove crank pulley. remove two 10mm or 8mm (i forget) bolts holding the cover. this will expose the timing belt.
remove cam gear cover, loosen tensioner, remove belt. it's fun. (not really)
