It actually works
I put this in my 2000 Jeep XJ these are notorious for running HOT! This product dropped the temp by 4 or 5 degrees. Doesnt sound like much but it is a help. Worth it in my opinion.

Worked for my cars
I've gotten this for a couple different cars now, on my first car was a 2005 chevy impala ss that was overheating I ended up flushing my coolant out putting in new and adding this and it ran way colder the next car I used it in was a 2006 subaru forester and it once again helped it run cooler although since I didnt flush the coolant that time it wasnt as big a difference, lastly I put it in 2005 scion xa and that one blew a radiator hose when it was overheating and so I had to top off the coolant and added this at the same time and once again it ran colder so in my experience this has worked

It’s worth trying
Voltage on whether this actually works or not is still ongoing only time will tell if it lowers the temperature.

It works great, for track or daily driver.
Great product. I run two bottles of this Hyper Coolant Super Coolant and all water in my 78 GMC Caballero drag car. Keeps coolant temperatures down between runs. Also provides excellent corrosion protection so you can run all water without any antifreeze or coolant for track purposes. I also run this stuff in both of my Ram trucks and my C5 Vette. Works just as well as Water Wetter but much cheaper.

I can't say I notice a huge difference since using this product. My car wasn't overheating. I think this is a good preventative and good product to refresh older coolant. The corrosion inhibitors and surfactants can't hurt.

I have no idea how to tell whether this type of product actually works and, if so, how can you tell? But I trust the science behind it and went with expert opinion in the end.

I used the super coolant for my vehicle and it worked as expected.
