Hello,
It is possible to have the thermostat failed at the stuck closed position, which is triggering the engine to overheat.
Another possibility is that the water pump is not circulating coolant properly, which could be due to a bad impeller.
If the thermostat is stuck closed, you will have a significant temperature difference between the upper and lower radiator hose, when the engine is at operating temperature or above.
