I was removing the water separator bolt to allow the water to drain when the bolt snapped in two. I was not tightening. I can't drive it to a dealership to get it replaced. Does anyone know if people can remove the broken bolt or have to replace the whole water separator? Btw, 2007 6.0 F250 Diesel.

 

Similar thread that may help.....doesn't look like just the screw is replaceable, but as an alternative it looks like you can remove the whole cover to give it a good cleaning
