Have you ever noticed liquid underneath your car? In the summer, it is most likely the water from your air conditioning system, which is normal. However, if you see other liquids, such as green, orange, or other brightly colored liquids, it might be coolant. Coolant is the fluid that keeps your engine cool. Coolant circulates through your engine, heater core, and radiator through channels and rubber hoses. The system is a closed system. If you see coolant outside your vehicle, you have a leak. These leaks usually develop in rubber exterior hoses and occasionally from the water pump or radiator. If you find a leak, it needs to be repaired or else the engine can overheat because of lack of coolant flow.
