Engine needs to be set to TDC, on compression stroke. Remove all the spark plugs. Find #1 cylinder. If your standing in front of the engine, its the cylinder closest to the front of the engine, passenger side. LOOSELY thread a spark plug in the #1 cylinder, only one or 2 turns. Turn the crank clockwise untill you hear a hissing noise (NOT a sucking noise) Take the spark plug out. Stick a straw or something in the #1 cylinder and turn the crank. Watch the straw-it will go up, and then begin to go back down. Back up the crank until it starts to go back up. Look at your timing marks on the timing belt cover and set the mark on the crank to the 0 mark on the cover. Thats TDC.

Now align the cams by lining up the marks on the cam and the marks on the back timing cover.

Install the belt, and tensioner as noted in the manual.

Turn the crank over 2 full revolutions, and make sure your timing marks on the crank AND cams still line up.
