INSTALLATION

PROCEDURE

1. INSTALL EGR COOLER ASSEMBLY

(a) Using an 8 mm socket wrench, loosen the 4 bolts of the No. 1 EGR pipe sub-assembly. HINT: As the bolts of the No. 1 EGR pipe sub-assembly are only to be loosened, it is not necessary to replace the EGR inlet gasket and EGR valve adapter gasket. If the No. 1 EGR pipe sub-assembly is removed, it is necessary to replace the EGR inlet gasket and EGR valve adapter gasket with new ones.

(b) Using an 8 mm socket wrench, loosen the 2 bolts of the EGR valve assembly.

(c) Install a new EGR cooler gasket to the EGR cooler assembly. NOTICE: Make sure that the claws of the EGR cooler gasket are toward the EGR cooler assembly side.

*a Claw

(d) Install a new EGR valve gasket to the EGR cooler assembly.

NOTICE:

Make sure that the claws of the EGR valve gasket are toward the EGR cooler assembly side.

(e) Type A: (1) Temporarily install the EGR cooler assembly to the cylinder head sub-assembly and EGR valve assembly with the 3 bolts and 2 nuts. (2) Tighten the 3 bolts and 2 nuts in the order shown in the illustration. Torque: 24 N·m {245 kgf·cm, 18 ft·lbf}

*a Bolt or Nut

(f) Type B:

(1) Temporarily install the EGR cooler assembly to the cylinder head sub-assembly and EGR valve assembly with the 2 bolts and 3 nuts.

(2) Tighten the 2 bolts and 3 nuts in the order shown in the illustration.

Torque:

24 N·m {245 kgf·cm, 18 ft·lbf}

(g) Connect the No. 3 water by-pass hose and No. 4 water by-pass hose to the EGR cooler assembly and slide the 2 clips to secure them.

(h) Using an 8 mm socket wrench, tighten the 2 bolts of the EGR valve assembly.

Torque:

10 N·m {102 kgf·cm, 7 ft·lbf}
