What is essential to check regarding windshield washer fluid?

Checking the level of the windshield washer fluid is essential for several reasons. First and foremost, maintaining an adequate fluid level ensures that drivers have a reliable means of cleaning their windshield, which is crucial for visibility while driving. If the level is too low, the washer system won't function properly when needed, especially in adverse weather conditions or when driving on roads that are particularly dirty.

Additionally, regular checks of the fluid level can prevent damage to the washer pump and associated components. Running the pump dry can lead to wear and tear or even failure, resulting in the need for costly repairs.

While factors like the color, age, or brand of the fluid can matter under certain circumstances—for example, certain colors might indicate contamination or appropriate usage—the primary focus should always be ensuring that there is enough fluid available to be effective when the situation necessitates its use.
