Just a couple weeks ago i noticed a on and off coolant leak near the water pump area, i noticed a huge puddle from that area 10 minutes after i turned the car off. Funny thing is, it doesnt leak when the car is running, it only leaks sometimes! Is this the pump?

 

I would wipe down everything around the water pump so you can see where exactly its leaking from. We cant make suggestions without pics either otherwise this thread turns into the guessing game
