I am in the process of this right now, but I cannot find the screw that allows me to pull the hoses back from the firewall. Could someone help me locate that? I have a 05 V50 T5.1. Use a smaller torx (I forget the size) and loosen the screw that is holding the pipe in place at the firewall
2. From the engine compartment pull on the hose that is connected to the pipe you are trying to separate. Note: I did not have to disconnect any of these connections, rather keeping the connections fixed helped me slide the pipe out through the firewall a little.
The hoses to the right are for the heater core
