I may have a leak?

What should I do
Top it off with some coolant, or as stated below, a small amount of distilled water. Check your hoses, expansion tank, and radiator for any signs of leaks.

Always check the coolant when the car is cold. There is significant pressure on the expansion tank when it's hot, I would not advise to open the cap until the car is cold.
