Car seat belts can be replaced. Below are the replacement methods and situations that require replacement: Seat Belt Replacement Method: Locate the wiring under the car seat, find the sensor wire for the seat belt buckle, and remove it. Remove the seat cushion, deactivate the airbag, locate the bolts securing the seat belt, and detach the seat belt buckle. Inside the seat cushion, find the seat sensor and remove it. Install the new seat belt buckle onto the seat, thread the wire through the hole, and insert the bolts. Install the weight sensor onto the car seat. Attach the new retractor and tighten it with a wrench. Reinstall the seat cushion onto the car seat and arrange the wiring at the bottom properly. Inspect the newly installed seat belt. Situations Requiring Seat Belt Replacement: If the internal retractor spring of the seat belt has aged, causing the seat belt to become too loose or fail to tighten promptly. If not replaced, in an emergency, a loose seat belt may allow the occupant to slip out, resulting in severe injuries. If the seat belt has endured a strong stretching force during use, even if undamaged, it should be replaced and not used further. If the car has been involved in a collision that triggered the airbag deployment, the seat belt must be replaced immediately.

From my research on automotive safety, seat belts can indeed be replaced, and this is crucial. If the belt shows signs of wear, tearing, or doesn't retract smoothly, it may fail to protect you in an accident. The internal retractors and sensors can degrade over time and become ineffective, especially as the vehicle ages, so regular inspections are necessary. I recommend addressing any issues immediately by visiting an authorized repair shop or dealership for replacement. They use genuine parts and conduct tests to ensure proper installation. The entire process typically takes less than an hour for removal and installation, but since it involves the vehicle's anchor points, DIY attempts may result in misalignment, compromising effectiveness. After replacement, remember to test the locking mechanism several times and check its coordination with the airbag system. After all, seat belts are the first line of defense while driving—don't risk safety to save a few bucks.

I've been driving for over a decade and had my seatbelt replaced once when I noticed it was sticking and making noise when pulled. The mechanic said it could be replaced easily—just remove the old one and install the new one—costing a little over 200 yuan and taking about half an hour. Now it's much smoother to fasten, without that clicking sound. Just a reminder to everyone: a seatbelt isn't just a strap—it contains springs and sensors, and any issues can affect safety. I usually have a mechanic check for wear and tear every two years, and if it's aged or after an accident, I replace it outright. Don't try DIY—it's easy to break things. Go to a professional shop—they can also check the overall system while they're at it.

Replacing the seat belt is no big deal. As a repair technician, I see this all the time. The process involves loosening the mounting bolts, removing the old belt and retractor, then installing a new set and aligning the buckle position before tightening. Special tools are required to avoid loosening or damaging components. After replacement, you must test the tension strength and whether the locking function works properly—otherwise, it might fail in a crash. I recommend going to an experienced shop for this, as it involves a core safety system, and careless handling could be risky. The cost typically ranges from 100 to 400 yuan, depending on the vehicle model and difficulty.
