Ok, so I bypassed the ox fitting thing today on my 03 b3000 and did a flush. I ran the system up to temp per the gauge. The heater was hot inside the heater core hoses were both hot, but the top radiator hose was not hot or pressurized and the radiator cap also was not at all. So.... yes dumb, I undid the radiator cap after the engine running for 15-20min. It did have pressure, but the coolant was cold..... wth is going on??? Is the thermostat not opening or is it something else
