If the timing belt is shredded, you may have another sort of problem. However, since you need to change it, set the crank at 0 degrees. If you look at the cam gear, you will see a small hole on the perimeter of the gear. By small, I mean about the size of a pencil lead. This has to be lined up with a notch on the head when the cam is at roughly the 6 o'clock position. You may need a mirror to see it. To install the belt, the 4 bolts on the water pump must be loosened and the pump slid to the right, as the pump pully acts as the belt tensioner. After the belt is slid onto the crank and cam gears, the pump pulley must be slid back and the pump tightened. Before I replaced the cover, I would turn the engine over by hand a couple of times to make certain I hadn't gotten it a tooth off. An easy way to determine if you have a hydraulic head, remove the cam cover, and with a lobe facing up, turn a lifter and look for a hole in the side of it near the top. If you have no hole, you have a hyraulic engine.
