When your radiator is leaking, how far you’ll be able to drive is going to depend on a lot of different factors. For instance, if it’s cold outside and raining, you’ll get more mileage before overheating than you would on a hot summer’s day.

That’s only if you have plenty of coolant, though, and the speed that you are traveling at is also going to make a difference in how quickly your vehicle is going to overheat. As such, it’s really best to pull over and call a tow truck to get your vehicle safely to the shop. The less you risk your engine overheating, the better.
