Put the piston cooling jet in position on the cylinder block and install the screw that holds the piston cooling jet to the block.2. Tighten the screw to a torque of 24 7 N m (18 5 lb ft).3. With the piston at the bottom of the bore, check the clearance between piston and piston cooling jet with a piece of wire (1) 0.63 mm (.025 in) thick. If the clearance is less than 0.63 mm (.025 in), make a replacement of the tube. The piston cooling jets must fit evenly against the cylinder block. If they do not, it will cause an oil loss in the engine oil system.End By:a. install engine oil pump
