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.
