Failing water pump caused an antifreeze leak as well as overheating. It also caused the heater to stop working as well when coolant would get low.

I haven't got the problem fixed yet. I will have to take it to the shop because I am not car SAVVY. I noticed my cars temperature needle rising alot so I would add coolant. Over time I seemed to be having to add a half a gallon to a gallon every two to three days. Today I decided to add water to the radiator and to the reservoir but I left the top off of the radiator when I started the car. The coolant flowed smoothly from the reservoir to the radiator. It started to leak around the hose in between the alternator and the belt on the supercharger. I have researched online figured out that I may possibly need to replace my water pump

I was sitting in front of a convenience store with my car running and my car began to smoke. I got out popped the hood of the car to see all my coolant leaking from my car.
