1.1 CYLINDER BLOCK AND CYLINDER LINER NOTICE: Always check to make sure cooling nozzles are open and aligned after piston installation. An obstructed, misaligned, bent, or damaged nozzle may not provide proper piston cooling. A loosened nozzle may cause a loss of main gallery oil pressure. In either case, piston overheating or lack of adequate lubrication may result in severe engine damage. 5. On current non-premium engines with cast iron pistons, install the bolt-on plate over the oil gallery orifice at the base of each cylinder bore. On premium engines with closed-end rods and forged steel pistons, install oil spray nozzles into these openings. See Figure 1-18 for location of nozzle.
