Reference Vehicle: MINI Cooper Mk1 3-Door Hatchback

Authentic Original Manufacturer Part

Where is this part fitted & What does it do?

This seat belt assembly is located on the Front Left Passenger Side (Nearside in the UK, Driver's side in LHD countries). It is secured to the B-pillar and the base of the passenger seat. This crucial component restrains the passenger during sudden deceleration or collisions, working in tandem with the pre-tensioner and airbag system.

Fitment Location: Front Left Passenger Seat (B-Pillar).

Context: Critical safety restraint for the front passenger.

Part Details, Materials & Symptoms of Failure

Material: High-tensile woven polyester webbing strap, heavy-duty steel mounting brackets, and a robust internal retractor spring mechanism designed to meet strict 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 does not pull out smoothly.
• The belt will not lock when yanked quickly (indicating internal inertia reel failure).
• The vehicle has been in an accident and the pre-tensioner has deployed, locking the belt permanently.

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 the manufacturer 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 - 1.5 Hours

Required Tools: 10mm spanner (for battery), Torx T50 socket (for seatbelt anchors), trim removal tools, flathead screwdriver.

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 (usually Torx T50), the lower anchor bolt, and the main retractor reel assembly bolt. Disconnect any electrical plugs for the pre-tensioner. Install the new belt in reverse order, ensuring all high-tensile bolts are torqued to manufacturer specifications.
