The worst part about replacing these parts on the pilot is bleeding the hydraulic tensioner. Also, the timing belt must have ZERO slack before the pin on the tensioner is pulled. I learned it the hard way and had to push the tensioner piston back in and put the release pin back in place. A breaker (and a pipe extension) was required to bleed the V-ribbed belt tensioner. As a weekend mechanic, it took me longer than a pro, but I saved $$
