I just bought a 2000 chevy impala. I think it has a coolent leek. After I drive the car and park it. Coolent starts leaking somewhere under the passenger side of the car. Now I can not see where the leak is coming from because there is a metal plate under the car blocking my view. This plate has holes in it where you can see coolent starting to gather and drip. I don't think it's the water pump because its dry. Radiator I think is fine. Theres no air in the lines because I've bleed them out.
