What is a common consequence of low coolant levels in a vehicle?

Low coolant levels in a vehicle can lead to engine overheating because the coolant is responsible for regulating the engine's temperature. It absorbs heat from the engine and dissipates it through the radiator. When coolant levels are low, there is insufficient fluid to absorb and transfer heat effectively, which can cause the engine to overheat.

Overheating can lead to severe engine damage, such as warped cylinder heads or blown gaskets, which can result in costly repairs. Maintaining proper coolant levels is essential for the efficient operation of the engine and to prevent overheating, which is a critical aspect of vehicle maintenance that should not be overlooked.
