Engine overheating occurs when a vehicle's engine temperature rises above the normal operating range. This can happen due to various reasons, such as low coolant levels, a malfunctioning thermostat, or a broken water pump. When the engine overheats, it can lead to severe damage, including warped cylinder heads or a blown head gasket. To prevent overheating, regular maintenance is essential. Checking the coolant level, inspecting the radiator, and ensuring the thermostat functions properly can help keep the engine at a safe temperature. If overheating occurs, it is crucial to stop driving immediately and allow the engine to cool down to avoid further damage.
