Confusion continues over coolant colors for cars. Of course, there is still the good old green stuff, but there is also orange, yellow (gold and amber), red, pink, blue and, if you mix the wrong things together, brown. Despite the rainbow of colors, all antifreeze starts out colorless.
Enter the cooling system. The cooling system is used to keep the engine from overheating. It does this by keeping the temperature at a constant so it runs more efficiently. The cooling system uses coolant to do this. Coolant is a 50/50 mixture of water and antifreeze. When you start your engine, a water pump circulates the coolant through the engine and radiator. Once the engine has reached a certain temperature, a thermostat opens to control the flow of coolant through the radiator.
