My car is leaking coolant. Some of it stays in but some of it leaks out onto the ground as I am pouring it in. Is it the intake manifolds or head gaskets that need to be replaced?

Best thing to do is to pressure test the cooling system and watch where the coolant is coming from, it may just be the water pump, a leaking hose etc.

Dan is right about having the cooling system pressurized to find the source of a coolant leak. The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. If the coolant loss is still evasive dye can be added to the cooling system that may indicate the source of the leak. A mysterious coolant loss may even be a sign of a head gasket that is not sealing well.

I had the same car and I replace the original radiator due to leak in the top right of the radiator. (When you look in front of the car. Not visible if you dont make a presure test.
