you don't need to remove the engine,remove fuel filter,coolant reservoir-swing onto top of engine,the p.a.s pump bolts onto the tensioner body with four 10mm bolts and think there are four 15mm nuts holding the tensioner body onto the block,once the nuts are off I think the two top long studs need removing and these have a star torx head on them to help you do this,sorry if I missed anything,good luck.
