There is no safe amount of time to keep driving once an engine is overheating. Some engines can suffer serious damage within minutes, while others may survive a short temperature spike if the driver shuts them down quickly. The problem is that you cannot tell from the driver's seat how close the engine is to damaging a head gasket, cylinder head, bearings, or other internal parts. If the temperature gauge moves into the red, a red temperature warning appears, or steam comes from under the hood, the right move is to pull over safely and shut the engine off. Trying to make it another few miles can turn a cooling-system repair into an engine repair. Overheating Damage Can Happen Faster Than You Think Engines are built to operate within a controlled temperature range. Once coolant temperature rises beyond that range, aluminum cylinder heads and other components begin expanding more than they were designed to. That excess heat can distort sealing surfaces, weaken ga ... read more
