Nissan Juke Service and Repair Manual : Removal and Installation

CAUTION:
Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat resistance, corrosion resistance and shape.

Perform the operation with the exhaust system fully cooled down because the system is still hot just after the engine stops.

Be careful not to cut your hand on the insulator edge.

REMOVAL

1. Remove Diesel particulate filter assembly.

2. Remove exhaust center tube and muffler from rubber mounting.

3. Remove exhaust center tube.

4. Remove main muffler.

REMOVAL

WARNING:
Any intervention on system during product life cycle is prohibited. If an intervention is required, the system will need to be entirely replaced.

The pressure measurement circuit must never be opened except at the adapters on the exhaust pipe.

Any intervention (excluding assembly) on system and more specifically, on the connection between stainless steel preformed tube and rubber hose is prohibited (sealing of the system would no longer be guaranteed). For example, intervention on screw, clamp, sensor, etc..

1. Remove engine under cover.

2. Disconnect exhaust pressure sensor harness connector.

3. Remove exhaust pressure sensor fixing bolt.

4. Remove exhaust pressure hose.

INSTALLATION

Install in the reverse order of removal.

CAUTION:
Always replace exhaust gaskets with new ones when reassembling.

If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, remove them.

When installing the insulator avoid large gaps or interference between the insulator and each exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left directions.

CAUTION:


In case clamp has been damaged or broken, it is necessary to charge the differential assembly itself, in order to avoid any leakage. it is not possible to replace just the clamp.

In case it would be necessary to change the washer of the coupling nut, then the coupling nut must be replaced itself as these two parts are an assembly part.

Any contact of the hose with products likely to damage them should be avoided.

The screw of the stainless steel preformed tube can only be tightened once (re-use is prohibited)
During any handling operation of the Diesel Particulate Filter pressure measurement hoses (handling, storage, assembly, etc.), the parts should never be folded or submitted to tension.

Installation is basically the reverse order of the removal.
