Reference Vehicle: Fiat 500 Mk1 3-Door Hatchback

Authentic Original Manufacturer Part

Where is this part fitted & What does it do?

This seat belt tensioner assembly is located on the Front Right Driver Side (Offside / O/S in the UK). It mounts inside the B-pillar behind the interior plastic trim. It is responsible for restraining the driver during sudden deceleration. It features a built-in pre-tensioner charge that pulls the belt tight milliseconds after an impact is detected.

Fitment Location: Front Right Driver Seat (B-Pillar).

Context: Critical safety restraint for the driver.

Part Details, Materials & Symptoms of Failure

Material: High-tensile woven polyester webbing strap, heavy-duty steel mounting brackets, and a robust internal retractor spring/explosive pre-tensioner mechanism designed to meet strict European road safety standards.

Common Symptoms of a Faulty Unit:

• The belt strap is frayed, cut, or severely worn (an automatic MOT / annual inspection failure).
• The retractor mechanism is jammed, very slow to retract, or hangs loosely.
• The belt will not lock when yanked quickly (indicating internal inertia reel failure).
• The airbag warning light is on, indicating a deployed or faulty seat belt pre-tensioner module.

The Massive Benefit of Buying a Factory Original Part: Never compromise on safety. Cheap aftermarket seat belts may not deploy correctly or withstand the immense forces of a crash. An original factory part ensures you are installing safety equipment exactly as Fiat intended. Plus, buying a high-quality recycled original part saves you as much as 70% compared to buying new!

Fitting Instructions & Garage Repair Estimator

Estimated Repair Time: 1.0 Hour

Required Tools: 10mm spanner (for battery), 16mm/17mm sockets (for seatbelt anchors), trim removal tools.

Brief Instructions: Safety First! Always disconnect the negative battery terminal and wait at least 15 minutes before working near airbag or pre-tensioner systems. Remove the interior B-pillar trim panels using plastic trim tools. Unbolt the upper D-ring anchor, the lower floor anchor, and the main retractor reel assembly bolts. Disconnect the yellow electrical plug for the pre-tensioner. Install the new belt in reverse order, ensuring all high-tensile bolts are torqued to manufacturer specifications.
