Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C8; Peugeot 807
• Product Codes: 14007784XX; 8974XF
• Other Numbers: 8974XF; 14007784XX

Function and Typical Use

The seat belt secures the occupant by restraining forward movement during sudden deceleration or collision. The assembly typically includes the webbing, retractor mechanism and buckle attachment points. Properly functioning belts are essential for airbag systems to perform as intended and for occupant safety in everyday driving and accident scenarios.

Replacement Procedure

Basic replacement steps for experienced technicians or competent DIYers:

• Disconnect the vehicle battery before starting work to avoid electrical hazards and to prevent unintended activation of restraint components.
• Remove interior trim panels to access belt anchor bolts and the retractor housing; keep fasteners organized for reassembly.
• Unbolt the anchor points and detach the old belt assembly from the retractor and buckle mounts.
• Install the new assembly in the correct orientation, secure all bolts and fasteners, and reinstall trim panels.
• Reconnect the battery and perform a functional check: ensure smooth webbing travel, correct locking under a quick pull, and secure buckle engagement.
• Always Follow Manufacturer Procedures And Torque Specifications During Installation.

Installation Recommendations

• Use the correct grade and length bolts; tighten to the manufacturer’s torque settings—if unknown, consult official service literature.
• Inspect mounting points and surrounding structure for deformation or corrosion; repair any damage before fitting the new belt.
• Do Not Reuse Bolts Or Components That Show Signs Of Stretch Or Damage.
• Some Vehicles May Have A Pretensioner Integrated In The Belt; If Present, Treat According To Manufacturer Guidance.

Why This Part Fails Most Often

• Deployment In A Collision: Belts And Pretensioners Often Require Replacement After An Accident.
• Wear And Age: Webbing Can Fray, Fade Or Lose Strength Over Years Of Use.
• Contamination: Dirt, Oils Or Chemicals Can Degrade Webbing And Retractor Mechanisms.
• Retractor Failure: Internal Springs Or Locking Mechanisms Can Seize Or Malfunction.
• Corrosion Or Damaged Mounting Points That Compromise Secure Anchoring.

Additional Notes

Searchable Part Numbers: Customers and workshops frequently look for this item by OEM codes 14007784XX and 8974XF. Replace seat belts that show visible damage or fail functional checks—never attempt repairs to webbing or locking mechanisms. Regular inspection as part of routine vehicle maintenance helps ensure occupant safety.

High-quality replacement safety belt designed for the left front (driver) position on Citroën C8 and Peugeot 807 models. This part corresponds to common OE references 14864390XX and 8974XF and is aimed at professional mechanics and experienced DIY enthusiasts who require a reliable, directly replaceable belt assembly. The belt restores occupant restraint function, meets original fitment points and mounting geometry, and is suitable for vehicles originally equipped with a 3-point seat belt system.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Citroën C8, Peugeot 807
• Product Codes: 14864390XX, 8974XF
• Additional Numbers: 14007784XX

Function And Description

The assembly is a 3-point driver seat belt with a retractor and inertia locking mechanism. It restrains the occupant during sudden deceleration and helps reduce movement in the event of a collision. Many original installations on these models incorporate a pretensioner and a load limiter to improve occupant protection; if the pretensioner has deployed in a prior event, the entire assembly must be replaced.

Installation Recommendations

Before starting work, take appropriate safety precautions. If the vehicle is equipped with a pretensioner, disconnect the negative battery terminal and wait at least 10 minutes to reduce the risk of accidental activation. Remove required trim panels to access the upper anchor, retractor and lower mounting bolts. Unbolt the anchor points and remove the old belt assembly. Install the new belt ensuring correct routing and alignment of the webbing, then torque all mounting bolts to the manufacturer’s specifications. After installation, check for smooth operation of the retractor and correct locking under sudden pulls. Inspect surrounding mounting points and trim for damage and replace fasteners if corroded or deformed.

Why This Part Typically Fails

• Wear And Abrasion: Repeated use can cause fraying or weakened webbing, especially where it rubs against trim or hardware.
• Contamination: Dirt, oils or chemicals can degrade webbing and internal mechanisms.
• Pretensioner Activation: In a collision the pyrotechnic pretensioner will fire and the belt must be replaced.
• Mechanism Seizure: Retractor spring or locking mechanism can stick due to corrosion, debris or long-term wear.
• UV And Ageing: Prolonged sun exposure can weaken webbing over many years.

Service Advice

Replace The Belt After Any Impact That Activates The Pretensioner Or If The Webbing Shows Cuts, Heavy Fraying, Burn Marks Or Stiffness. Always Verify Mounting Points And Fasteners For Structural Integrity. For Best Results Use Appropriate Torque Settings From The Manufacturer And Follow Repair Manuals For Trim Removal And Reassembly.
