If your car is leaking antifreeze from the engine, it is important to address the issue promptly to prevent any further damage. The first step is to identify the source of the leak. Here are a few possible reasons for the antifreeze leak:

1. Cooling system hose: Inspect the hoses connected to the radiator and engine for any cracks, holes, or loose connections. A damaged hose can cause antifreeze to leak. If you find a damaged hose, it will most likely need to be replaced.

2. Radiator: The radiator itself could have a leak. Look for any signs of coolant pooling around the radiator, or check for visible damage like cracks or holes. If the radiator is damaged, it may need to be repaired or replaced.

3. Water pump: The water pump is responsible for circulating the coolant through the engine. If the pump is faulty or has a leak, it can cause antifreeze to leak. Inspect the area around the water pump for any signs of leakage or damage.

4. Head gasket: Another possible cause of an antifreeze leak is a blown head gasket. This can create a pathway for coolant to leak into the combustion chamber or mix with engine oil. Signs of a blown head gasket may include white smoke from the exhaust, milky oil, or engine overheating.

It is crucial to address the antifreeze leak as soon as possible, as driving with low coolant levels can lead to engine overheating and potential damage. If you have the necessary skills and tools, you may attempt a DIY fix depending on the severity of the issue. However, it is highly recommended to consult a professional mechanic to accurately diagnose and repair the problem.
