What does the coolant fluid look like?

Coolant fluid typically has a bright color, often green, orange, yellow, or pink, depending on the type and manufacturer. It is a mixture of water and antifreeze, which gives it a slightly viscous texture. When new, it is usually clear and translucent, but as it ages, it may become darker or cloudy due to contaminants. Always check your vehicle's coolant level and color regularly to ensure proper engine function.
