💪 Prestone Super Radiator Anti-Rust (AS170Y): The Ultimate Solution for Rust Prevention! Review

I use this on a large generator. It's hard to find in stores. It works great on things that don't run, but maybe 20 minutes a month. It improves the corrosion resistance of conventional antifreeze.

As long as the antifreeze is clean, only the water pump lubricant and anti-corrosion additives "wear out". This product complements both. Eliminates the hassle of removing and safely disposing of used antifreeze.

I called Prestone because I started noticing dirt in the radiator and coolant reservoir about a week after adding it. They said that this product has been out of production for at least 5 years. So the product was old and maybe it has something to do with it. I gave the container a good shake before putting it in my jeep.

I've been a mechanic in my own workshop for over 50 years. I've been using this product for ages. Ethylene glycol does not degrade over time and does not need to be replaced. The additives in antifreeze go bad, and a can of this rust inhibitor and water pump lube rejuvenates it for a fraction of the cost. Act.

Modern anti-freeze was not available until some time after the Second World War. However, corrosion has always existed. Almost immediately after World War II, most cars used water, an anti-corrosion agent, and when needed, a third agent (sometimes methanol) as antifreeze. Because the boiling point of water is higher than most modern antifreeze, serviceable cars of the era were not as prone to overheating as vintage cars that run on antifreeze today.
