What would be a sign of low coolant levels?

A visible coolant leak is a clear indication of low coolant levels in the vehicle’s cooling system. Coolant leaks can occur due to various issues such as cracked hoses, damaged radiator, or a defective water pump. When coolant escapes from the system, it not only leads to a decrease in the overall volume of coolant but can also result in engine overheating if the levels drop significantly.

In this situation, a driver would notice puddles or stains under the vehicle where coolant may be seeping out. Detecting a visible coolant leak prompts further investigation to identify the source of the leak and address it before more serious engine damage occurs.

Other indicators, such as increased engine noise, excessive tire wear, or poor air conditioning performance, may not directly relate to coolant levels. While they can be symptoms of other underlying mechanical issues, they do not specifically signal low coolant levels in the same straightforward manner as a visible leak does.
