I'm replacing the heater core in my 1988 Sable GS 3.0L.
I have the dashboard out. I have the heater core bypassed since early last summer and now I'm in the final stage of pulling the heater core.
Before I can do that though I have to disconnect the A/C
lines on the firewall side.
I bought the spring lock coupling tool set.
I managed the top line.
But the lower line (condenser line) just will not disconnect. I struggled with it almost two hours yesterday and it will not go.
I used the 5/8" spring lock tool which seems like the only size that fits.
I push it into that doughnut thing from the firewall side in the dirrection outward and then I pull the line toward me to disconnect but it will not move.
Anyone has any tips, advice?
Also I found a doughnut shapped spring under my car after disconnecting the top line? Is that from the spring lock doughnut thing?
Is the lower line the same mechanism as the top line?
I'm stuck with this and my fingers are hurting from working the spring lock tool and pulling the line.
Any help, pointers, pictures or anything at all much appreciated.
Sorry for the long post.
