Super Tech’s 50/50 coolant meets and exceeds cooling and boiling point requirements for most modern engines, is priced well, and has some favorable reviews. According to 42 reviews on, Super-Tech’s 50/50 coolant has 4.5 stars out of 5. Not only does Peak and Prestone boast these standards, so does Super Tech’s coolant.īut don’t take my word for it.

Universal coolants use unique OAT-based corrosion packages with proprietary organic acids (such as carboxylate) to provide broad spectrum protection.īoth Prestone and Peak, two of the most popular brands of Coolant raise boiling points of water to 265F and lowers the boiling point to -34F. Coolant must interact well with these materials.Īccording to Walmart’s description for Super Tech 5050 Antifreeze coolant, this coolant is In addition, many components attached to engines are plastic.

Most modern engines today don’t have iron blocks anymore and have lighter aluminum blocks.

With that out of the way, most of the concerns people have with any value-brand coolant is if it’s safe for their engine’s and does it meet the heating and cooling requirements for your area (if you live in a hot or cold climate.)

Coolant also has lubrication properties, keeping moving parts in your cooling system spinning efficiently, mostly the water pump and evident when you try to wash the stuff off your hands.
