I have owned a 1998 Cadillac Deville for almost a year. Since I've owned this car its been one problem after another.I've replaced the battery, the alternator, the starter and the radiator along with new radiator hoses. The most recent one has given me the most trouble. One day while driving, the check coolant level indicator came on. When I turned the car off, I noticed a significant amount of antifreeze leaking from the front of the drivers side. At times it seems like it's a slow drip but now more recently it's been pouring out.
What is causing my car to lose antifreeze? Is it the radiator that I recently replaced?

 

Very likely the water pump, located at the back of the right side cylinder head, or for orientation purposes the cylinder head at the front of the car. If you remove the shield at the bottom of the car you can see up to the top, look for the bottom of the pump to see if the water is pouring out of the weep hole.
