Lot's of great info on this forum. Hey Tech, were you born in a volvo? Lot's of great advice!!!
Have you ever changed the headliner in a 93 850GLT? Mine is sagged out. Any tricks would be greatly appreciated!

 

I have pulled them but you might be better off having it done it is failry cheap.
That will save you alot of trouble.. If you try it your self you have to remove all the old stuff then wire brush the entire Board then buy the Material and 3M spray adhesive. The spray the Board and put the Material on.

 

I agree with Tech on this. I restore cars as a hobby and have done a few headliners. It is a pain in the butt and just nasty work. If you do it yourself, remove the headliner from the car, dont do it while its installed! Remove the side and pillar trim and the dome light and I am guessing it should come out, but never done it on a Volvo yet. You need 3M headliner / trim adhesive and a thin headliner foam. You can get these at local auto paint / body stores. The adhesive is a spray and is really messy if you dont use it right, so practice with a piece of cardboard and some spare fabric, because once you lay down the fabric, it wont come back up if you mess up.

Hell, just drop 250.00 and get it done professionally.... I wish I had...
