Beck/Arnley coolants are an ethylene glycol based, pre-diluted antifreeze/coolant for superior corrosion and rust protection. Beck/Arnley coolants are popular for engine cooling systems that require the "extended life" coolant.
Bel-Ray coolants use a non-toxic propylene glycol formula designed for efficient heat transfer and cooler running engines. Known to be suited for racing conditions, this coolant protects systems from corrosion and extends the life of most vehicles.
Havoline, a division of Chevron, offers both conventional and extended life coolants. The Company's coolants feature protection against winter freeze ups and minimizes the chance of a summer boil over. The Company's extended life coolant features an organic additive formulation that is free of silicate, nitrite, borate, phosphate, nitrate and amines.
The products sold by Motorcraft have gone under extensive laboratory and on-the-road testing to maximize vehicle performance. Motorcraft coolants provide year-round antifreeze, anti-boil and corrosion protection.
PEAK Performance is a subsidiary of Old World Industries, which is known for its runway deicing products for airports. The Company leverages its expertise in deicing to automotive antifreeze and PEAK technology is compatible for all vehicles, regardless of the make model, or year. The Company's coolants claim to protect the cooling system against rust and corrosion, even in the highest of temperatures.
Since 1927, Prestone has been named for its outstanding protection in car's cooling systems. Prestone utilizes a variety of chemistries for differing vehicles and each formula provides a high degree of performance durability and protection against temperature extremes and corrosion of all system metals.
Shell makes an ethylene glycol based coolant for heavy-duty, gasoline, and natural gas powered engines. Due to the special chemistry in Shell coolants, the antifreeze reduces water pump failures, eliminates hard water scale deposits, and improves heat transfer.
Zerex, known to use premium chemistry for vehicles' coolant systems, provides excellent freeze, boil and corrosion protection for all metals. The protection covers heavy-duty applications and even protects aluminum. Zerex coolant is made by Valvoline.
