So, excuse me if this has been beat to death, I've used the search but didn't see anything that really helped.

Back in August my fiance and I were involved in an accident in my '02 F150. Long story short, we were doing 45mph, went into a ditch, hit a concrete culvert, deploying the air bags. My question is does my truck have seat belt pretensioners? I've seen some sites saying, I do, some saying I don't. What all will I need to replace other than the airbags? Crash sensors? SRS module?

Thank you all in advance!
Pic of the damage for fun.

 

I'd replace the sensors. Probably located around the core support somewhere. Not sure if it has pretentioners, they're usually by the belt retractors.

 

I wanna say that it doesn't have the pretensioners as I can freely pull the seatbelts, and they still retract. But I'm not sure.

 

They do have pretensioners except those truck with center belts.
They don't work unless there is a 'forward motion' to cause them to lock such as caused by applying the brakes. Or hitting something.
Naturally when just pulling them up they won't lock.
In the old days you pulled the belt tight and was not movable.
Now they are fully adjustable without pulling them tight because now thay lock up from a forward actuating lockup.
Look under the plastic cover at the mechanization and see how they are supposed to work.
This not to say one could have been damaged from the accident trying to hold more than 100 pounds plus inertia body wight in check as the locks were designed to do..
Good luck.
