AC lines

[AHofner]

I'm in the process of pulling the HVAC unit. I've got the dash apart and just need to undo the heater core lines and the AC lines coming in through the firewall. I have the disconnect tools from Lisle, but have no idea how to use them. best I can tell, they slip around the line and you push them into the flare which then releases some sort of lock? I'm stumped and I've come a long ways to throw in the towel now. I really want to take a good look at the blend door to see if it's causing the low air flow on the pass. side. I've been using the write up that scbroder did as my guide (huge help, thank you!) but the AC line fittings are giving me problems.

Any help would be appreciated.

Here is the procedure from the service manual. In a nutshell, yes you insert the tool into the open end to release the spring. You might have to push the line together slightly, insert tool, then pull apart.





1. Recover the refrigerant system (Refer to 24 - Heating and Air Conditioning/Plumbing - Standard Procedure) .

2. Remove the secondary retaining clip from the spring-lock type refrigerant line coupler.

3. Fit the proper size A/C Line Disconnect Tool 7193 or equivalent over the coupler cage (1).

4. Close the two halves of the A/C Line Disconnect Tool 7193 or equivalent around the coupler (2).





NOTE: The garter spring may not release if the A/C Line Disconnect Tool 7193 is not squarely inserted into the coupler cage opening.

5. Push the A/C Line Disconnect Tool 7193 or equivalent into the open side of the coupler cage to expand the garter spring (3). Once the garter spring is expanded, pull on the refrigerant line attached to the female half of the coupler until the flange on the female fitting is separated from the garter spring and cage on the male fitting.

6. Open and remove the A/C Line Disconnect Tool 7193 or equivalent from the refrigerant line coupler (4).

Yeah, just make sure the pressure is all off the system, put the tool on the line and push it toward the coupling, turn it back and forth to get it to get under the garter spring, when it goes in just pull the cpl. apart. bg
