Can You Keep Driving When the Car Radiator Boils Over?

[MacJordan]

You should not continue driving when the car radiator boils over. Here are the specific reasons why: 1. After the radiator boils over, the engine's heat dissipation becomes poor, and the excessively high temperature causes components to expand, reducing the clearance between parts. 2. The high temperature decreases the viscosity of the engine oil, accelerating wear on various components. If you do not stop immediately and take appropriate measures, the engine may suffer severe damage or even catastrophic failure. Here are the specific reasons why a car radiator may boil over: 1. Insufficient coolant. The primary function of coolant is to lower the engine's temperature. If there is too little coolant, the engine will overheat. 2. Water pump failure. The engine block has a complete water circulation system, with a water pump installed at the upper outlet. Its role is to pump out hot water and pump in cold water through the pulley to cool the engine. If the water pump fails, the engine's water circulation system will not function properly. 3. Cooling fan failure. The cooling performance of the fan directly affects the engine's heat dissipation capability.
