Yes, that part is pretty straightforward to design and execute. Plumbing the coolant flow is where it gets fun. I need a new branch off the coolant circuit on the other side of the existing monovalve for the bypass circuit. Right now that branching occurs in the existing monovalve body. This means finding a "Y" or "T" fitting of the right diameter and splicing that in, and routing the new branch off that fitting to the newly added monovalve / bypass circuit. ------------- Max Charleston SC
