i heard a chain like noise while it was over heating and i was almost home so i kept on driving but it sounded like a chain every time i like stepped on the gas... ps its not the head.. ive changed, radiator, fan clutch, thermostat, t-stat housing.. so what else?
What is this noise i heard on my car while it was overheating?
You should have stopped and turned off the engine as soon as you noticed the overheating. By continuing to drive, you may have caused further and permanent damage.
The noise is speculation ( especially not knowing what type of vehicle you have ) but it could have been the timing chain, valves, scorched rod or crank bearings, etc.
