Why does my car make a noise when I start it in the mornings?
i noticed that the car makes this weird noise in the mornings as I turn it on to go to work. The noise sounds as if the car was running out of water. However this goes on for about 10 or 15 seconds and then it goes away for the entire day, it is not there when I turn the car to go back home from work. And it is not until the next day early in the morning that the car does this same noise.

You may have air in the coolant system.
To bleed it allow the car to cool and remove the radiator cap. Turn the heater setting all the way hot. Allow the car to reach operating temprature and then top off radiator and reserviour with a 50/50 mix of anti-freeze and distilled water.
