Clean the piston cooling jets and inspect the piston cooling jets for damage. Ensure that the valve is free to move within each piston cooling jet. Replace any damaged piston cooling jets. The procedure for checking that the alignment of the piston cooling jets is described in Specifications, "Piston Cooling Jet Alignment" for more information.
If the crankshaft is installed, use Tooling (A) to rotate the crankshaft in order to access the mounting flange for the piston cooling jet.
Install a new O-ring seal (3) (not shown) onto piston cooling jet (2).
Install piston cooling jet (2) into the oil passage in the cylinder block. Note: Ensure that the piston cooling jet is correctly installed into the oil passage in the cylinder block before tightening the bolt.
Install bolt (1). Tighten the bolt to a torque of 9 N m (80 lb in).
Repeat Step 2 through Step 4 in order to install the remaining piston cooling jets. End By:
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install" for the correct procedure.
