Coolant is usually light in color, such as orange, pink, or turquoise, so it can be easily distinguished from other fluids under the vehicle. Its texture is watery, and it gives off a pleasant smell after rolling.
Coolant leaks can range from minor issues like a loose clamp to serious problems like a broken water pump or leaking heater. This type of leak requires immediate attention as it deteriorates quickly and can damage the engine.
