What Causes Engine Overheating Warning?

[DelAdelyn]

Engine overheating warning can be caused by the following reasons: Coolant Leakage or Insufficient Coolant: A coolant system leak leads to insufficient antifreeze, which in turn causes the antifreeze temperature to rise. If the antifreeze level is found to be low, the first step should be to check for leaks. Cooling Fan Malfunction: A faulty cooling fan prevents timely heat dissipation from the antifreeze when the car engine operates at medium to high speeds, causing the antifreeze temperature to rise and leading to issues like "boiling over". Water Pump Failure: When the water pump fails, the water on the engine's heat conduction side cannot circulate promptly, resulting in a rapid rise in water temperature after the engine starts.
