i dont have air con. Its a sr, its the pipes going from the heater matrix to the engine bay, there the metal ones that connect to the rubber pipes in the engine bay
no there more to the left hand side. Just behind the inlet mani where the heater matrix water pipes are. Its the metal ones where the water goes through to the matrix
the pipe's are linked to by pass the matrix but its the metal ones coming out the bulk head. There in the same place as the pic about but my are curved an face down but one has been cut off.
sounds like it is the heater matrix pipes . cause the metal ones are attached part of it . some one will have joined them for a reason . usually cause the matrix is leaking. or its cause they broke one . have fun replacing that
