Understanding Coolant Leaks: Causes and Signs
Before diving into the repair process, it's crucial to grasp the common causes of coolant leaks and the signs that indicate a potential issue. Identifying these factors early on can help prevent more significant problems and costly repairs down the line.
Common Causes of Coolant Leaks
Coolant leaks can arise from various components within your vehicle's cooling system. Here are some of the most frequent culprits:
