Why does the coolant leak out of the radiator?
A coolant leak. While driving, the incoming air flow allows the radiator to keep the coolant temperature down. But when the car is driving at low speeds or at a standstill, it’s up to the fan to do that job. If the fan isn’t kicking in, then there a few things that could cause that.

What can I do if my coolant leak is not obvious?
Sometimes when a coolant leak is not obvious you must create pressure inside the system to force the leak to appear. This is done using a cooling system pressure tester which you can get from Amazon for about $55.00 (US).
What happens if you lose antifreeze with no apparent leak?
