What light indicates low windshield washer fluid?

[VonHeidi]

Low windshield washer fluid is indicated by a light showing a container with two water splash symbols. Engine coolant should not be too low but can be slightly overfilled: If there's no coolant in the expansion tank when it needs to be replenished, the vehicle will experience coolant deficiency. This may lead to abnormal engine overheating, even causing cylinder scoring and engine damage. It's acceptable to slightly overfill coolant beyond the maximum line, as long as it doesn't overflow during high temperatures. Different coolants should not be mixed: The color of coolant actually represents its different chemical compositions. Mixing different types of coolant is not recommended as it may cause chemical reactions or crystallization, affecting heat dissipation. Coolant only needs replenishment, not replacement: Coolant maintenance is just an upkeep item, not a service item. Modern vehicles use long-life coolant that can last for hundreds of thousands of kilometers without issues. Generally, there's no need to replace it within 5 years - regular inspection and replenishment are sufficient.
