how do these conections come apart

This conection was the bottom conection on the radiator for the tranny coolant line.


And these two are the lines going into the ac radiator.

Looks kinda like the way a Ford fuel filter is connected. but I am just guessing.

I'll second that. On some fords there for the fuel filter on vehicles that have fuel injection there is a tool that slides into the connection to release a clip, that does look very similar.

Hope this helps.

I have the tool if you want to try it. Let me know.

You can also buy them at most part stores and if I remember they are not that expensive. There are two different tools that give you a varity of sizes.

I tracked down those tools, thanks for the heads up.
