HEATING PIPE NISSAN ALMERA N16 2.2DI

Very good. I am trying to try to remove the heating pipe from the Nissan Almera 2.2 di of the motor block. Apparently it is simply embedded to pressure I suppose that with some type of Toric Board or something similar, my doubt is whether to take it out you simply have to throw and then change some type of joint to insert it again or it is something more complex of what I imagine I imagine. Forero can help me very much in advance.
