Fitment And Function

This unit is intended for the left front (driver) position on Peugeot 406 models that use the listed part numbers. It functions as a three-point inertia-reel restraint: the webbing runs over the occupant and is stored on a spring-loaded reel that locks under sudden deceleration. Many front belts on this vehicle family may incorporate a pyrotechnic pretensioner and/or load limiter depending on model year and equipment level; if the original system included a pretensioner, it must be inspected after any collision.

Installation Recommendations

• Always follow the vehicle manufacturer’s repair procedure. Remove interior trim panels carefully to access anchor bolts and the retractor.
• Before starting work, disconnect the battery and wait the manufacturer-recommended time when dealing with pretensioners or airbag system components to avoid accidental deployment.
• Unbolt the lower anchor(s) and the retractor securing bolts. Note routing of the webbing and any harness connectors for pretensioner or seatbelt warning sensors.
• Fit the new belt in the same orientation, ensure the webbing is not twisted, reconnect any electrical connectors, and tighten bolts to the manufacturer’s torque specification.
• After installation, perform a functional check: smooth extension/retraction, audible locking under sharp pull, and correct sensor/warning lamp behaviour if applicable.
• If the original belt’s pretensioner has been deployed in an accident, replace the pretensioner and associated components as required by the manufacturer.

Why This Part Most Commonly Fails

• Wear And Abrasion: Frayed or cut webbing from repeated use, sharp edges, or foreign objects.
• Contamination: Dirt, grease, or chemical spills causing the retractor to stick or slow its action.
• Corrosion Or Seizure: Moisture ingress or rust on mounting bolts and retractor components leading to restricted movement.
• Pretensioner Deployment: Activation in a crash makes the belt and pretensioner unusable and requires replacement.
• Incorrect Routing Or Installation: Twisted webbing or improper anchoring reduces effectiveness and accelerates wear.

Notes For Mechanics And DIYers

Searchable identifiers for quick reference: 96384991XX, 8974CT. Check the vehicle’s service manual for specific fitment variants and torque values. When replacing a front belt, inspect anchor points, seat structure, and pretensioner circuitry to ensure the complete restraint system remains safe and compliant.
