I have a 2.3 how do i install the timing belt

Align harmonic damper mark at TDC with #1 piston at top. You'll have to remove harmonic damper on front of crank. (You can do it without removing the damper, but it's a real pain in the rear.) This WILL require an industrial strength impact wrench to break the bolt loose. Pull spark plugs. Makes last step easy and you can use a screwdriver to make sure #1 is at top. You'll see tick marks on the crank pulley, the cam pulley and the auxillary shaft pulley. These marks must line up. Use a straight edge (ruler, piece of flat metal stock, etc.) to make sure they're aligned. Pull tensioner arm back and lock it there. Install belt around pullies. Now comes the tricky part. Whne you release the tensioner, the auxillary shaft will rotate at least one tooth off of alignment. Release tension and compensate auxillary shaft postion. You want the marks aligned with the belt under tension. Now using a long wrench, rotate the engine clockwise by turning the crank balancer bolt. After 2 complete revolutions back to TDC, confirm timing mark alignment on the pullies. If they're off, redo it until they're aligned. Good luck.
