View Full Version : Special Ac line Disconnect tool?

09-17-2013, 10:22 PM
I am trying to remove this hose from a 2004 Dodge Sprinter and have it repaired. Problem is I have not seen a connector like this before and all my normal ac disconnect tools do not work on it. This hose is attached to the rear of the rear ac compressor and runs to the ac unit on the roof.

It *looks* like a fuel line disconnect I saw on my Father-In-Law's Ford. If it's the same thing, you need a tool like this:

I have tried various disconnect tools like the one you linked. It seems like they are not long enough to do anything when you put the ridge inside the connector it just goes all the way in without pushing anything.

Hmmmm... Well, I'm sure you are on the right track. There must be an extra long one available for that, or you can just make one. Hardware stores have different diameter pipe. You could get one the right diameter, cut it in half and glue it to the tool I linked to where the arches already are. Just a thought.
Good luck.

I may end up having to make a tool, I was hoping that someone had some experience with these fittings and could give me some guidance.

I can only offer what the service manual describes for the rear a/c plumbing:

(1) Recover the refrigerant from the refrigerant system (Refer to 24 - HEATING & AIR CONDITIONING/ PLUMBING - STANDARD PROCEDURE - REFRIGERANT SYSTEM RECOVERY).
(2) Remove the secondary retaining clip from the spring-lock coupler.
(3) Fit the proper size A/C line disconnect tool (Special Tool Kit 7193) over the spring-lock coupler cage (Fig. 38).
(4) Close the two halves of the A/C line disconnect tool around the spring-lock coupler.
(5) Push the A/C line disconnect tool into the open side of the coupler cage to expand the garter spring.
Once the garter spring is expanded and while still pushing the disconnect tool into the open side of the coupler cage, pull on the refrigerant line attached to the female half of the coupler fitting until the flange on the female fitting is separated from the garter spring and cage on the male fitting within the disconnect tool.
NOTE: The garter spring may not release if the A/C line disconnect tool is cocked while pushing it into the coupler cage opening.
(6) Open and remove the A/C line disconnect tool from the disconnected spring-lock coupler.
(7) Complete the separation of the two halves of the coupler fitting.
