Hi,
About a week ago a radiator hose blew. The hose was replaced properly. After several
days the car began to over heat again. The hoses were fine. It's a six cylinder engine. We have replaced the radiator after flushing out the original one. We have also replaced the water pump, and thermostat. The engine continues to overheat. I am at a loss as to what to do next. Is there a sensor i'm not familiar with?
Thank you,
Barb

It sounds like you have replaced everything. Also, when it overheats, do you hear the coolant boiling and are you sure it is overheating and not just a bad sensor?

Once more question. Do you have to add coolant to it on a regular basis?

What size engine is in this? There should be air bleed screws located on your engine. Just need to know the size to further assist. Sounds like its airbound.
