I have an 02 ram 2500, cummins HO. I want to change the radiator overflow bottle. It looks like it can be removed by simply pushing it up from the bottom. Is that the case or is there something else to it? thanks

 

There are some round dimples on the side of the bottle that attach it to it's holder.
Sometimes you can just push in on the dimple with your fingers but more often I'd resorted to a long thin screwdriver to wedge the holder from the bottle.

 

Thanks, I will give 'er a try. My luck though when I try force something I usually break it.

 

isn't it already broken? why do you want to replace it?
