Please note that the coolant you see draining out of my truck is non-toxic, which is why I let it drain on the ground. Non-toxic anti-freeze is made of Propylene Glycol instead of Ethylene Glycol and is safe for use in systems where ingestion may occur. If you are using Ethylene Glycol based anti-freeze you will need to capture it and dispose of it properly based on your location.
