Just to give a good tip -
Line up the crank to TDC using the timing marks on the out side of the oil pump which is a notch and the cut out on the inner side of the crank sprocket then mark the cams with tip-ex correction fluid - this way you know they are spot on - I also mark them in three places along with the crank sprocket - when removing the old belt push the long section of the belt in hard using a lever and pin the tensioner - then remove the tensioner - the cams will flick round once the tension is removed - but try to let them loose slowly using a spanner on the cam bolts - use bulldog clips or clothes pegs to hold the new belt in the right place on each cam and cable ties on spanners to hold them against the springing action works great - fit the tensioner and pulley assembly to the right torque and lever the new belt to release the pin on the hydraulic tensioner - turn over three times jobs done
cheers
Steve
PS removing the power steering pulley helps with removing the timing covers too
