REMOVAL

I - REMOVAL PREPARATION OPERATION

• Position the vehicle on a two-post lift (see Vehicle: Towing and lifting) (MR 392, 02A, Lifting equipment).
• Remove the engine style cover.
• Disconnect the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery).
• Remove:
  • the scuttle panel grille (see Scuttle panel grille: Removal - Refitting) (MR 393, 56A, Exterior equipment),
  • the engine undertray,
  • the engine tie-bar (see 19D, Engine mounting, Lower engine tie-bar: Removal - Refitting, 19D-13),
  • the catalytic converter (see 19B, Exhaust, Catalytic converter: Removal - Refitting, 19B- 29) (K9K/760,762,764,766,768),
  • the catalytic pre-converter (see 19B, Exhaust, Catalytic pre-converter: Removal - Refitting, 19B-23) (K9K772).

II - OPERATION FOR REMOVAL OF PART CONCERNED

1 - First fitting of the exhaust gas cooler recirculation assembly

• Remove:
  • the mounting bolts (1) from the rigid exhaust gas recirculation pipe,
  • the snap-fit clamp (2) using the (Mot. 1567),
  • the rigid exhaust gas recirculation pipe (3).

2 - Second fitting of the exhaust gas cooler recirculation assembly

• Remove:
  • the bolts (4) of the rigid pipe bracket from the cylinder head,
  • the bolts (5) of the rigid pipe on the exhaust manifold then discard them in the waste bin,
  • the bolts (6) of the rigid pipe on the exhaust gas cooler,
  • the rigid pipe and its seal then discard them in the waste bin.

REFITTING

I - REFITTING PREPARATION OPERATION

• All the bearing faces must be carefully cleaned.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the new rigid exhaust gas recirculation pipe with a new seal,
  • the new exhaust gas recirculation pipe mounting bolts.

1 - First fitting of the exhaust gas cooler recirculation assembly

• parts always to be replaced: Exhaust gas recirculation rigid pipeparts always to be replaced: exhaust gas recirculation pipe boltparts always to be replaced: Exhaust gas recirculation pipe clip
• Refit the new rigid pipe, equipped with new bolts on the manifold, a new seal on the manifold and a new clip.

Note: The Parts Department only supplies clips for the rigid pipe with a tangential bolt.

• Adjust the rigid pipe in its location by screwing, without tightening, the bolts on the manifold and centring the rigid pipe on the EGR support at the timing end.
• Torque tighten:
  • the rigid pipe bolts on the exhaust manifold (36 N.m),
  • the bolt of the clip on the rigid pipe (5 N.m).

2 - Second fitting of the exhaust gas cooler recirculation assembly

• parts always to be replaced: Exhaust gas recirculation rigid pipeparts always to be replaced: exhaust gas recirculation pipe boltparts always to be replaced: Exhaust gas recirculation pipe seal
• Fit the new rigid pipe equipped with a new seal and new bolts on the manifold.
• Fit without tightening:
  • the bolts of the rigid pipe on the exhaust gas recirculation cooler,
  • the bolts of the rigid pipe on the manifold,
  • the bolts of the rigid pipe on the cylinder head.
• Torque tighten:
• the rigid pipe bolts on the exhaust manifold (36 N.m),
• the bolts of the rigid pipe on the cylinder head (25 N.m),
• the bolts of the rigid pipe on the exhaust gas cooler (12 N.m).

III - FINAL OPERATION

• Refit:
  • the catalytic pre-converter (see 19B, Exhaust, Catalytic pre-converter: Removal - Refitting, 19B-23) (K9K/772),
  • the catalytic converter (see 19B, Exhaust, Catalytic converter: Removal - Refitting, 19B- 29) (K9K/760,762,764,766,768),
  • the engine tie-bar (see 19D, Engine mounting, Lower engine tie-bar: Removal - Refitting, 19D-13),
  • the engine undertray,
  • the scuttle panel grille (see Scuttle panel grille: Removal - Refitting) (MR 393, 56A, Exterior equipment).
• Connect the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery).
• Refit the engine style cover.

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Disconnect the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery)

• Disconnect:
  • the air temperature sensor connector (1),
  • the vacuum pipe (2) between the turbocharger regulation valve and the turbocharger outlet air pipe,
  • the vacuum pipe (3) between the air pressure sensor and the turbocharger outlet air pipe.
• Loosen the turbocharger outlet air pipe clips (4).
• Remove the turbocharger outlet air pipe (5).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove:
  • the clips of the exhaust gas recirculation pipe using the (Mot. 1567),
  • the exhaust gas recirculation rigid pipe (6).

REFITTING

I - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the exhaust gas recirculation rigid pipe,
  • the clips to the exhaust gas recirculation pipe using the (Mot. 1567).

II - FINAL OPERATION

• Refit the turbocharger outlet air pipe.
• Torque tighten the turbocharger outlet air pipe clips (5.5 N.m).
• Connect:
  • the vacuum pipe between the air pressure sensor and the turbocharger outlet air pipe,
  • the vacuum pipe between the turbocharger regulation valve and the turbocharger outlet air pipe,
  • the air temperature sensor connector,
  • the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery).
