New water pump
New thermostat
Flushed and burped system
No leaks
Vehicle runs at perfect temperature.
Pulled heater core. Flushed and checked for leaks. No problems.
NOW:
At operating temp, both heater core hoses are COLD. For the life of me, I can't figure out why coolant isn't getting through those hoses. I know on some year Explorers, there is a type of heater vacuum control valve, but mine doesn't have that. It's just one hose in, one hose out. Both hoses are cold.
I'm completely lost. It's been pretty cold lately, and some heat would be nice!
