Im sure its just me missing it, but I think you need a bypass-hose between the thermostat and radiator, so that the water will sirculate in the engine when there is no need to run through the radiator... As it looks like now, the flow stops when the thermostat is closed?

Daniel..you didn't miss anything I just never mentioned it in the thread but trust me in my many conversations with Meziere I have asked that same question. Here's what I have been told by two different Tech's...a bypass is not needed and that all I need to do is drill a 1/8" hole in the Thermostat flange to allow some flow.
