Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Peugeot 307 CC
• Product Codes: 8974JX
• Additional Numbers: NFP

Function And Fitment

The seat belt assembly secures rear-seat occupants by locking webbing during rapid deceleration and maintaining proper positioning in normal driving. This unit is specified for the left rear position (rear, driver side) of the Peugeot 307 CC and is supplied without the buckle. Compatibility is commonly referenced by the part number 8974JX; ensure the belt matches your vehicle’s mounting layout and connector type before fitting.

Replacement Guidance

Replacing a rear seat belt typically involves the following steps and precautions. These notes are intended for qualified technicians or experienced DIYers:

• Prepare: Park on level ground, set the parking brake, and work with adequate lighting and trim tools to avoid damaging panels.
• Safety First: Before working near pyrotechnic components (pretensioners) or airbag systems, disconnect the vehicle battery and wait the manufacturer-specified time for system discharge. Follow vehicle manufacturer procedures for SRS work.
• Access: Remove interior trim panels to expose the belt retractor, anchor bolts, and routing points.
• Unfasten: Remove bolts securing the retractor and lower anchor. Keep track of bolt types and locations for reassembly.
• Fit New Unit: Position the new belt assembly, route the webbing exactly as the original, and hand-thread bolts before torquing to manufacturer specifications.
• Torque And Test: Tighten mounting bolts to the vehicle manufacturer’s torque values. Check webbing movement, automatic locking function, and correct stowage. Reassemble trim and perform a final functional check.

Installation Recommendation

Use OEM or equivalent fasteners and follow Peugeot torque specifications for all anchoring points. Because seat belt systems are integral to occupant safety, final checks must ensure the retractor locks under a sharp pull and the webbing is free of twists. If the assembly includes a pretensioner or shows signs of prior activation, replace the entire affected restraint component. If uncertain, have installation verified by a qualified technician.

Why The Part Most Often Fails

• Accident Impact: Pretensioners can activate during a collision, rendering the retractor or webbing unusable.
• Wear And Tear: Fraying, contamination, or abrasion of the webbing from repeated use or sharp edges reduces strength and can lead to failure.
• Retractor Problems: Internal mechanisms can seize or lose spring tension, causing the belt to fail to retract or lock properly.
• Corrosion And Fastener Degradation: Mounting bolts and anchorage points exposed to moisture or salts may corrode, compromising secure attachment.
• Improper Use Or Installation: Incorrect routing, twisted webbing, or loose mounting can prevent correct operation.

Additional Notes

Searches for this part are often performed using the code 8974JX. Replace seat belts after any collision or if the webbing or mechanism shows visible damage. Always follow Peugeot service procedures for safe and compliant installation.

Replacement Procedure

Intended for qualified technicians or competent DIYers with basic tools. Typical replacement steps:

• Disconnect The Battery: Always disconnect the vehicle battery and wait an appropriate time before working on seat belts to avoid accidental airbag/pretensioner activation.
• Remove Interior Trim: Carefully remove the necessary trim panels to access the rear belt retractor, anchor bolts and buckle fastenings.
• Unbolt The Retractor And Anchors: Remove bolts securing the retractor and lower anchor. Keep track of bolt types and torque values.
• Disconnect Electrical Connector (If Present): If the belt assembly includes a pretensioner or sensor connector, unplug it following safety precautions.
• Fit New Unit: Position the replacement assembly, route webbing correctly, and fasten bolts to the manufacturer’s torque specifications.
• Reconnect Battery And Test: After reassembly, reconnect the battery and check belt locking, retraction, and buckle engagement. Verify there are no dashboard fault indications related to restraints.

Why This Part Fails Most Often

Rear seat belts typically stop functioning correctly for several reasons: webbing wear or fraying from prolonged use or snagging; Dirt, debris or rust causing the retractor to stick or lock; Internal mechanism failure due to age; Buckle wear or contamination preventing reliable latching; And deployment-related damage if the pretensioner operated in a collision. Regular inspection and prompt replacement of damaged belts are essential for occupant safety.

Installation Recommendations

• Follow Manufacturer Procedures: Use correct torque values for anchor bolts and follow Peugeot guidelines for trim removal to avoid damage.
• Observe Safety Precautions: Always disconnect the battery before starting work on restraint systems and wait the recommended time to discharge capacitors.
• Check Electrical Connections: If the assembly has a pretensioner or sensor, ensure connectors are clean and seated correctly.
• Test Functionality: After installation, perform a functional check of webbing retraction, locking under sudden pull, and buckle engagement.
• Use Replacement Hardware If Damaged: Replace corroded bolts, clips or trim fasteners to ensure a secure mounting.

Notes For Professionals

This seat belt assembly is intended as a direct-fit replacement. Technicians should verify correct routing and secure mounting during installation. Because restraint systems are critical for safety, any signs of prior deployment, damage or inconsistent operation should result in replacement of the complete assembly rather than repair of individual components.
