3. Tighten bolts (7) to a torque of 22 N·m (16 lb ft) in the sequence that is shown in Illustration 4.

4. If the engine has a low mounted oil filter on the left hand side, install the oil filter base. Refer to Disassembly and Assembly, "Oil Filter Base - Remove and Install".

   If the engine has a right hand side oil filter, follow Steps 4.a through 4.d in order to install blanking plate (12).

   1. Install bolts (11) to blanking plate (12).

   2. Position a new joint onto blanking plate (12).

   3. Install the assembly of the blanking plate to the assembly of oil cooler (6).

   4. Tighten bolts (11) to a torque of 22 N·m (16 lb ft).

5. Remove the plugs from tube assembly (9). Remove the caps for the fuel return from the cylinder head and from transfer pump (8). Install tube assembly (9) to the cylinder head and to transfer pump (8).

6. Follow Steps 6.a through 6.e in order to connect engine wiring harness (4).

   1. Place the harness in position.

   2. Connect engine wiring harness (4) to position sensor (2) for the fuel injection pump.

   3. Connect engine wiring harness (4) to oil pressure sensor (13).

   4. Connect engine wiring harness (4) to solenoid (1) for the fuel injection pump.

   5. Install new cable straps in order to secure engine wiring harness (4) to the assembly of oil cooler (6).

7. Remove the plugs from all plastic tube assemblies (3). Remove the caps from the appropriate ports. Install plastic tube assemblies (3).

8. Fill the cooling system to the correct level. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct procedure.

9. Check the level of the engine lubricating oil. Refer to Operation and Maintenance Manual, "Engine Oil Level - Check" for the correct procedure.
