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 the alignment of the piston cooling jets is described in Specifications, "Piston Cooling Jet Alignment".
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) onto piston cooling jet (2).
Position piston cooling jet (2) in the cylinder block. Install bolt (1). Tighten the bolt to a torque of 9 N m (80 lb in).
Repeat Step 2 through Step 4 for the remaining piston cooling jets. End By:
If the engine is equipped with a balancer, install the balancer. Refer to Disassembly and Assembly, "Balancer - Install" for the correct procedure.
If the engine is not equipped with a balancer, install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install" for the correct procedure.
