PEAK Long Life 50/50 Prediluted Antifreeze & Coolant offers all of the same benefits in a convenient pre-diluted antifreeze with no need to add water. Its inhibitors provide maximum cooling system protection against damaging rust and corrosion.

Old World Industries (OWI) is an American automotive and chemical company best known for their PEAK brand of motor oil, antifreeze and other automotive products.

A non-amine-type high-grade coolant liquid specially for diesel engines that offers numerous benefits such as superior metal corrosion resistance and cavitation erosion prevention. It can be used all-year round, as it serves as an antifreeze in the winter and a coolant in the summer.

PEAK® All Makes All Vehicles Antifreeze + Coolant.

Antifreeze is a tinted liquid that you put (along with water) in your radiator to help regulate engine temperature. Its key ingredient is ethylene glycol, which lowers water's freezing point and raises its boiling point. This helps prevent the water in your radiator from freezing, boiling, or evaporating.

Newer coolants use an Organic Acid Technology (OAT) and last up to twice as long as older coolant. In some cases these long-life coolants can last over 5 years or 100,000 miles.

Stay Frosty High-Performance Coolant is the best coolant for high-performance cars. Why? Because it affords the same features as Race-Ready, but contains a 30 percent mix of propylene glycol to 70 percent water.

The main difference between antifreeze and coolant is the ratio of water to antifreeze. Antifreeze is mainly made up of ethylene glycol or propylene glycol, while coolant is made up of a 50-50 mixture of water and antifreeze.

You need to check your engine coolant at least twice a year before summer and winter, ideally. Although, this advice may vary between car manufacturers. Coolant should be topped up whenever the level drops below the guide marks.

Prepare a 50 to 70% mixture of Antifreeze + Coolant concentrate and water. Add mixture to the overflow reservoir to the level marked on the tank.

PEAK® Antifreeze + Coolant is designed for use in all North American, Asian and European passenger cars, SUVs, motorcycles, and light/medium-duty trucks, regardless of make, model or year.

Your vehicle needs anti-freeze throughout the year, not just during the winter. It helps to protect your engine from corrosion, aids heat transfer and prevents rust & scales from building up. In hot temperatures it prevents your engine from overheating by raising the boiling point of the water in the cooling system.
