If there is no flow, what would you suggest from that point? I'll check tomorrow. I'm feeling heat in all my hoses, so I assume there is flow based on that. Not just the general engine bay warmth kind of heat.
No real upgrades in the performance sense. I switched to Open cooling using the Spectra radiator, and got a newer style t-stat housing so I could put a temp sensor for my stand-alone electric fan controller, which just controls a 2000 xj oem efan around 220. Otherwise, it's all factory equivalent parts.
