There's a company that advertises in Hemming's motor news called snake oil. All they do is seat belt repair but you will have to send & use another while you wait or order from dealer. I don't think that is something they will repair for safety reasons. Or get a generic replacement set.
Replace the belt and buckle as one unit.
To replace the seat belt buckle on a 1996 Geo Prizm, first, remove the plastic trim covering the seat belt assembly by unscrewing any screws or clips. Next, detach the old buckle by unscrewing it from its mounting point, then disconnect the wiring harness if it has one. Install the new buckle by reversing the process: attach it securely to the mounting point and reconnect any wiring. Finally, replace the trim and ensure the new buckle functions properly.
You don't need a torque wrench when you unscrew something.
Buckle up.
The parts of a belt buckle are the prong, buckle and belt.
Remove the front seat, four bolts hold it down to the floor and unplug a pig tail connection under the seat. you will then have access to the seat belt buckle in between the seat and the center counsel.
The 4.0 liter OHV - V6 engine and the 5.0 liter - V8 engines used in a 1996 Ford Explorer XLT use a timing CHAIN
To replace the driver side pushbutton seat belt buckle on a 1997 Toyota Previa, first, remove the plastic cover around the seat belt assembly by unscrewing any screws or clips. Disconnect the seat belt buckle from its mounting point by unbolting it and unplugging the electrical connector if equipped. Install the new buckle by reversing the removal steps, securing it firmly and ensuring the belt operates correctly. Finally, replace the plastic cover and test the seat belt functionality.
With some belts there are clips in the reverse side, which you can use to change the buckle. What do you do if the belt you want doesn't have clips? Well I cut the stitiching or remove the rivets, depending on which the belt has, then replace the buckle and refasten it with safety pins, or if you have a thinner belt you may prefer to staple it. Hope this helps.
Best to go get a used one & replace it
call a mechanic.
I don't see how you could install just the buckle. I suggest you go to almost any salvage yard and get a replacment belt/buckle assembly. Replace the whole thing.
