Last issue on this rebuild, my engine is not staying cool and I don't understand why. I am checking coolant temp via my OBD2 scan tool. With the car at idle or driving it will heat up to 223 and maybe more if I let it, the fan doesn't turn on at any point and to fix this I tried replacing the coolant temp sensor, coolant temp switch, and replaced relays, all to no solve the problem and lead me to fixing the fan by directly wiring the fans to the battery. I know the thermostat is good because it opens in boiling water, and I can only believe the water pump is good because it is brand new and is a good brand from O'Reilly's where I work. However with this being said it still gets hot, with the cap off I see no coolant moving which gives me a red flag but I don't know why, the thermostat has to be open at 180 or close to it and the water pump must be moving coolant because the system has pressure and with a funnel used to get air bubbles out, they come out. I flushed the heater core and radiator so they aren't clogged and I completely rebuilt the entire motor nothing can be clogged as I would know. Wondering if anyone can point me in a directed of what to try next, cooling fans need to turn on when the car reaches temp and I need to see coolant rushing past the open cap. I don't know what to try next, please help!
