Why Do Older Cars Tend To Develop Coolant Leaks?

Coolant leaks are a fact of life on just about any older vehicle. There's no set age or mileage where they typically start, but it's a good bet you'll experience one sooner or later once you cross the warranty threshold. Coolant leaks can range from relatively minor to incredibly severe, but any coolant loss can potentially result in overheating and engine damage. While these leaks may be unavoidable, knowing why they occur and what to expect can be helpful.
