Can You Keep Driving When the Car Radiator Boils Over?
2 Answers
You should not continue driving when the car radiator boils over. Upon noticing the boiling, first pull over to the side of the road but do not immediately turn off the engine. There are various reasons that can cause a car radiator to boil over, though typically only one specific issue is at play each time. If you shut down all other functions, the water temperature may remain excessively high, potentially damaging the engine. The correct approach is to idle the engine, open the hood, turn on the heater to dissipate heat as quickly as possible, and ensure the car is parked in a shaded area. Next, the owner should check if the coolant level is sufficient. This situation often arises from the owner neglecting to top up the coolant regularly. It is crucial to use the same brand and model of coolant when refilling, as mixing different types may cause chemical reactions that render the antifreeze ineffective. Additionally, a coolant leak could be the reason for the low level. In such cases, the owner should thoroughly inspect for any leaks and have them repaired promptly.
Never drive when the radiator boils over. As a veteran driver with over 20 years of experience, I strongly advise stopping immediately. I remember one summer on the highway when my radiator boiled over, and I didn't stop in time—resulting in an overheated engine that caused the cylinder head to warp, costing me a fortune in repairs. Continuing to drive will cause the engine temperature to skyrocket, leading to blown gaskets, internal part deformation, and even potential explosions or fires, endangering lives. After stopping, turn off the engine immediately and let the car cool for at least half an hour before checking if the coolant is sufficient or leaking—otherwise, the problem will worsen. If necessary, call a tow truck—never take the risk. A boiling radiator is a matter of life and wallet—don't take it lightly.
