I'd like to hear from DML about how his is plumbed. I have never heard a bad thing about Dick Wright or about a bad plan of his, so my curiosity has gone up.I'd love to save the space and avoid an extra radiator and there is plenty of room to install an electric fan behind the radiator on my MCI7. It is a trick to avoid creating an accidental bypass for the DD, and to be able to flow coolant without running into the closed thermostats on the DD when parked.
