Before I try to answer this I need you to tell me that you have opened the bleed bolt located on the thermostat housing and purged the air pockets from the engine cooling system with the engine idling. You also need to confirm that the water pump is pumping by removing a heater hose and running the engine with the heater hose end disconnected and look for flow to confirm that the water pump impeller is not compromised in any way reducing flow. Should have stopped after one thermostat replacement.
