Antifreeze Recycling Equipment and Old Coolant

Can old antifreeze really be recycled and used again in your car's coolant system? A friend of mine claims it is good as new after antifreeze recycling equipment. I would never reuse motor oil in my engine and seems like the same theory would apply to antifreeze. What is the story?

Antifreeze recycling equipment is used in state of the art auto shops to recover coolant from automobile and recycle it to a "like new" condition. I understand your reservation about using recycled antifreeze and the fear of it possibly damaging your radiator or engine. However, this is not the case. The reason has to do with the properties of ethylene glycol which is the main ingredient in antifreeze. The ethylene glycol will not wear out. Its the additives and dirt and grime build up that require you to flush your radiator and replace the antifreeze. Modern antifreeze recycling equipment separate the ethylene glycol from the additives and filter out the dirt and grime. Then new additives are mixed into the still good ethylene glycol and reintroduced into your car's coolant. The new antifreeze will last 2 years or 30,000 miles.
