Can You Still Drive When the Car Radiator Boils Over?
2 Answers
You cannot drive when the car radiator boils over. After the radiator boils over, the engine's cooling efficiency decreases, leading to excessively high temperatures. The expansion of components will reduce the clearance between parts. The hazards of a boiling radiator include: elevated coolant temperature reduces oil viscosity, accelerating wear on various components. If not stopped immediately, it can cause severe engine damage. The causes of a boiling radiator are: 1. Insufficient water level, rust, or leaks in the radiator; 2. Cooling system malfunction; 3. Thermostat failure; 4. Dirt accumulation on the radiator. Solutions for a boiling radiator include: 1. Refilling the radiator with water; 2. Replacing the thermostat; 3. Adding antifreeze.
Never keep driving when the radiator boils over! I've seen too many cases where stubborn drivers ended up with completely ruined engines, costing tens of thousands in repairs. A boiling radiator indicates severe engine overheating and total cooling system failure—possibly due to coolant leaks, a seized water pump, or a broken fan. Continuing to drive will cause cylinder scoring, warped engine blocks, and drastically reduced engine lifespan. For safety, immediately pull over, turn on hazard lights, and let the vehicle cool naturally before checking coolant levels. Make it a habit to inspect the cooling system monthly, replace coolant regularly, and always check before long trips. If overheating occurs, never gamble—call a tow truck instead. This small expense saves major headaches. Remember these details to avoid costly disasters.
