It works, keeps engines cooler.
My 1972 Oldsmobile 442 Convertible runs hot with the original 4 core radiator and belt driven fan. This keeps it from overheating. I also use this in my modern BMW cars for both the engine cooling and the air charge cooler for the turbos. Especially in my 750 with twin turbo "hot V" where the turbos are in the V of the block and get really hot.

Works well in ford modular 4.6 2V engine. Runs nice and cool

It actually works.
Well I had a bad radiator cap and ended up with a very dilute coolant (almost clear). I decided to use this as it prevents corrosion, claimed to lower operating temperature and lubricates the water pump plus I do not live in an area where freezing is a problem. After draining out an equal volume from the radiator and adding this I started the engine and ran it. I was surprised that the temperature was 20 degrees lower.

Works well!
I use this in my '67 SS Nova. I have had chronic overheating at idle in summer. After every trick in the book it's much better. I tried this and it made a solid difference of 5 degrees. I'll take it! 5 degrees doesn't sound like a lot, but it's the difference between an overheat and not. Got me down to a manageable idle temp. Best $ I've spent in a while.

A radiator coolant additive that reduces engine temps and corrosion protection!
I use this super coolant additive for both of my vehicles and it works as expected. I would use it again. Check with your manufacturer first to see if its compatible with your vehicles.

Nice Additive
Love this stuff works great helps a little especially when it's very hot out. Make sure you put good antifreeze in your car and add a bottle of this, also change your thermostat to a lower temperature in the extreme summer heat. If you like add a couple extra radiator fans in front of your condenser with a separate toggle switch I added two 8-in fans and my temperature in the extreme heat stays between 180 and 195. It used to go up to over 220.

works as advertised!!
good stuff! lowers temp and adds needed chemicals for old antifreeze

Didn't notice much difference
My 87 VW Westphalia has been running a bit warmer than I like, even though it's a new radiator. Figured this might help, but really haven't noticed a difference.
