  1. Thoroughly clean the threads on threaded nut (1) and the cylinder head.

  2. Install a new seat washer (3) into the recess in the cylinder head.

    Note: If the original seat washer is reused, the projection of the fuel injection nozzle will be incorrect.

  3. Put a 2.0 mm (0.08 inch) bead of 4C-5591 Anti-Seize Compound on the first two threads of threaded nut (1).

  5. Carefully tighten threaded nut (1) to a torque of 30 N·m (22 lb ft). Remove any excess Anti-Seize Compound from fuel injection nozzle.

    Note: Do not rotate the fuel injection nozzle after installation. The seal which is made by the anti-seize compound may break. A broken seal may allow leakage past the seat of the fuel injection nozzle.
