What Causes Sudden High Engine Temperature While Driving?
1 Answers
Sudden high engine temperature while driving can be caused by a leaking radiator obstructing water circulation, insufficient coolant leading to radiator water shortage, or malfunctioning temperature sensors or gauges. If you notice high engine temperature, first find a safe and shaded place to pull over. Keep the engine idling - do not turn it off, as shutting down would stop both the cooling fan and coolant circulation, potentially causing further overheating. When detecting engine or vehicle overheating, add antifreeze or seek professional repair services. For other failures like water pump or thermostat issues, seek assistance promptly. Additionally, understand that engine coolant temperature reflects the cooling system's operational status - engines perform optimally within specific high-temperature ranges. Normal engine operating temperature typically ranges between 90-95°C. Temperatures exceeding 100°C indicate overheating. After running for some time to reach optimal temperature, antifreeze circulates extensively to dissipate heat, effectively protecting the vehicle. Automotive engines require specific operating temperatures - neither too high nor too low. Engine-generated heat often exceeds conventional air cooling capacity. Vehicles are equipped with engine coolant temperature sensors, usually displayed separately on the dashboard.
