What type of leak is indicated by a red/green color?

The indication of a red/green color leak is typically associated with the engine cooling system. This color can denote the presence of antifreeze or coolant, which is essential for regulating the engine's temperature and preventing overheating.

Coolant is often dyed in bright colors, such as green, orange, or pink, for easy identification. The presence of these colors in a leak suggests that coolant is escaping from the system, which could point to issues like a cracked radiator, a damaged hose, or a failing water pump.

In contrast, engine oil usually appears brown or black, transmission fluid is typically a reddish color, and brake fluid is usually clear or slightly yellow. Understanding these distinctions is crucial for vehicle maintenance and safety, as identifying the source of a leak can help address potential mechanical issues before they lead to more significant problems.
