There is no leak in the radiator, but the anti-freeze in the radiator doesn't stay in the radiator? The low coolant light comes on, even tho i've added coolant. Do I need a radiator. Please help if you can.

The coolant is leaking somewhere.
It doesn't evaporate.

It could be leaking into the engine.
Or the heater core
or out the water pump
or various gaskets.

Filling the system with coolant and then putting a pressure tester on it will help find the leak 90% of the time. (Unless it's inside the engine)
