TD5 seat belt

Hi all , the drivers seat belt is stuck on my missus's td5, it comes out about an inch and stops, if you leave it for a minute it comes another inch?? i assume the tensioner is kaput so have ordered a new belt/tensioner. Has anyone evr changes one before as advice would be gratefully received. ie how do i remove the trim? once the trim is out of the way is there a knack to fitting the new one or does it just bolt on?
thanks in advance

Not sure how you get the trim off, but before you buy a new one slacken the mounting bolt and let the mechanism hang loose. You should find that the tensioner will release.

Tighten the bolt until the belt will not pull out, position the mechanism in the position that the belt pulls out and tighten up the bolt.

Hi,
Drop the door seals down to show B post, two lugs at the front two at back clip over the B post seam, put small blade in top of trim finisher and pull towards center of vehicle. Belt assembly is just bolted on with a location lug.

Thanks, will do it tomorrow hopefully all will go well.

Seat belt changed. No bolts to undo the trim thought. Removed both front and rear seals around the pillar, the pilaar unclipped with metal clips on both sides, had to leaver out a small bracket clipped in at the bottom then just 3 bolts to rmemove the seat belts-takes about 20 mins!!
thanks all
