Companies that have been around for that long are usually those that make really great products that their customers love.
As mentioned earlier, Valvoline is also the maker of Zerex coolants but its coolant brand has also gained massive recognition due to the quality of its products.

One of the world’s leading automotive spare parts and coolant manufacturers, ACDelco is one of the few brands that almost every vehicle owner is familiar with. The American company is owned by General Motors and therefore produces and markets coolants for the automobile manufacturer.
ACDelco was founded in 1916 by the founder and owner of General Motors as an automotive component, and the brand changed names over its long history even though its products are still reliable.
Its specifically formulated coolants are known to provide resistance to corrosion by protecting brass, cast iron, steel, solder, and copper components while equally providing superior temperature protection for the aluminum components of your vehicle’s engine.

It clears away that rust and restores your cooling system to normal working condition. Also, it is able to restore your engine’s ability to the cooling system and consequently makes it last longer.

Another coolant brand is Evans Cooling Systems Inc., manufacturer of the popular Evans coolant. The brand pioneered the first commercial waterless engine coolants, boasting more than 20 years of delivering non-aqueous engine coolant products to the market.

Rather, its coolants are made up of the same basic propylene glycol, eliminating the issues that are common with water-based coolants. Plus, the coolants are non-toxic and cause no harm if wrongly ingested since the active ingredient is used as a sweetener in many products.
Furthermore, the Evans coolants provide a superior form of engine protection as they prevent voids and corrosion due to the absence of water, allowing for a longer and healthier engine. As far as temperature is concerned, this brand’s coolants can protect up to a boiling temperature of 375°F and cold temperatures below -40°F, which is better than what traditional coolants offer. A key example is Evans Coolant EC53001.
