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.

Cold Radiator Temps
When I flushed my coolant system. I had replaced the coolant with two bottles and the rest with distilled water. My engines temps in my 6.5 Diesel stay right at 180. Freaking perfect. I live in PHX, AZ so I never have to worry about it freezing. But our hot summers at 120 degrees leave me worried free knowing I have the best coolant in my truck.

It does work
Product does seem to keep engine a few degrees cooler, i use on my intercooler and does keep that much cooler than using 50/50 antifreeze now i just use this.

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.

Radiator coolant additive
I was pretty excited to try this product but only saw a 5 degree drop in temperature at most. I expected a lot more.
