The Stovebolt Site Forums The Shop Area Interiors Urethane window is cracked how do I remove it

My vent window was installed using urethane and it cracked. Any suggestions on how to get it out. I was thinking running a razor blade down the sides and pulling as hard as possible.

Not sure what year truck your working on but on my 52 I soaked the glass where it is held in the frame by glass tape. I then tapped a screw driver between the glass and the frame starting at the top. This worked well for me but your situation may be different. I have also used Kerosene to soak the window tape.

The only way I,he ever had success with is to either use a propane torch to heat the frame (you will need to remove the frame from the assembly to avoid damage to the rubber, then probably repaint) or to break the glass out and dig/cut what's left of the glass and sealant out. You could try taking the frame out and soaking in alcohol or lacquer thinner, urethane doesn't play well with either of these. If you use the heat route, avoid the fume's and smoke, I'd do it outside if possible, the fumes are nasty!! Good luck. John

I've heard both gas and kerosene work for the tape but not for the urethane. I ended up beating the window out and using a utility knife down the sides. I then used a small chisel ( or screwed driver) to pull it the rest of the way out. Frame need to be repainted after that process. Took about 2 hours to get it out. If anyone has a better way I would love to hear it in case I ever have to change another window.

Best plan is to not use urethane for this purpose. I am glad that it is expensive or I would have been tempted to use it. I thought better of it, as I was thinking about the poor guy who had to come in behind me (most likely me). That stuff does not give up holding on.
