Can You Continue Driving with High Water Temperature?
2 Answers
You should not continue driving when the car's water temperature is too high. The consequences of driving with excessively high water temperature are as follows: 1. Engine impact: High water temperature causes the lubricating oil temperature to rise, reducing viscosity and making it prone to leakage. The overall engine temperature increases, preventing the formation of an effective oil film and affecting engine power output. 2. Cylinder damage: Continuing to drive can easily cause deformation and damage to the cylinder block and cylinder head, and in severe cases, replacement of new cylinder blocks and heads may be required. The reasons for high water temperature in a car are as follows: 1. Cooling fan not working: The cooling fan may be controlled by a thermostat switch or a water temperature sensor. 2. Insufficient cooling medium: (1) Antifreeze: High-end cars require antifreeze to be added year-round. (2) Water or distilled water: Temporary substitute. 3. Radiator blockage: (1) External blockage: Use water or air to remove dirt. (2) Internal blockage: This affects the circulation of the coolant and creates pressure, leading to two possible outcomes: radiator leakage or particularly high water temperature during high-speed driving.
The sudden rise in water temperature suggests you should definitely not continue driving, as this can quickly damage the engine. Issues like cylinder head warping or piston seizure can occur, leading to extremely high repair costs or even total vehicle write-off. I've seen many lessons learned in similar situations: immediately stop and turn off the engine in a safe location, then wait at least half an hour for the engine to cool before inspecting. Common causes include insufficient coolant, fan malfunction, or a stuck thermostat—simply check the fluid level and fan operation. If coolant is low, carefully add distilled water after cooling, but it's best to call a tow truck for professional repair. Delaying could lead to more severe failures; prioritizing safety is the wisest choice.
