take the pulley off..... there are 3 marks one on each cam and on on the oil pump

line cams up.....loosen tensioner.....stick drill bits in the cam alignment holes.... wrap belt around cams and work it down to the crank.... that way you align only one mark at the bottom..... snug the tensioner almost tight..... bump the tensioner pulley with a rubber mallet so it takes slack but doesnt lossen again..... lock the tesioner down.......DONE
