Intermediate silencer

F4R or K4J or K4M

Tightening torques
rubber mounting bracket bolt on the resonator	0.8 daN.m
rubber mounting bracket bolt on the body	2.1 daN.m

REMOVAL

• Raise the vehicle on a lift.
• Remove the undershield.
• Cut the exhaust line (Exhaust chapter, Exhaust general information, page 19B-1).

• Remove:

• resonator mounting bolts (1) to the rubber mounting bracket,
• the resonator.

Note: If the rubber mountings are damaged, mark the position of the bracket on the body, then replace the "bracket - rubber mounting" assembly.

INSTALLATION

WARNING

Cut the new resonator pipe (Exhaust chapter, Exhaust general information, page 19B-1)

• Refit:

• the resonator,
• the sleeve (Exhaust chapter, Exhaust general information, page 19B-1).

• Tighten to the following torques:

• rubber mounting bracket bolts on the resonator (0.8 daN.m),
• rubber mounting bracket bolts on the body (2.1 daN.m).

• Tighten the couplings while relieving the exhaust line to ensure its correct alignment (Exhaust chapter, Exhaust general information, page 19B-1).
• Check that all heat shields on the exhaust line are present and correctly secured.
• Check that there is no contact with the underbody.

WARNING

• Replace any damaged heat shield without fail.
• Do not reuse a used sleeve.
• The coupling bolt and nut assembly must be positioned so as to avoid any risk of contact with the underbody.
