Utilizing Cor-Guard ® technology, this formula is designed to protect cooling system parts from corrosion and damage. Cor-Guard® increases uptime by instantly stopping the. spread of rust, corrosion, pitting, gunk, grime, and buildup.

Prime antifreeze+coolant (concentrate) is for all vehicles; all makes, models, years & fluid colors. The extended life formula is safe for use with all types of metals & elastomers; including aluminum. Prime will guard against temperature extremes and the affects of rust, corrosion, and premature water pump failure.

Prestone's inhibitor technology is a one-stop product for all light duty vehicles, making it easy for you to choose it in your business. Here's why: More thermally stable than commercial available ELC OAT AFC. Absolute compatibility with all modern engine metallurgy & polymers.

OAT coolant additives stands for Organic Acid Technology. These additives rely primarily on carboxylic acids and azoles. They generally do not contain silicate or borate. Heavy-duty versions may also contain nitrite or molybdate, or both, but they still fall in the OAT family.

Prestone MAX will work in your vehicle: It's guaranteed to work in All Vehicle Makes, Models & Years with Gas or Diesel engines. It mixes and works with all antifreeze + coolant colors and formulations including OAT, POAT, HOAT & IAT; G05®, G11®, G12®, G12++®, G13®, G30®, G40®, & GG40®.

Optimizes engine temp, prevents freezing, PLUS protects parts from buildup & corrosion. While ordinary antifreeze+coolant only manages 2/3s the job, Prestone's Total Protection handles the complete job. Designed to last and protect vital engine parts for 10 years/300,000 miles.

A coolant that's too acidic can cause corrosion, while one that's too alkaline will stop being effective at preventing corrosion. The ideal pH level for engine coolant is 1.5 pH. The pH of new antifreeze is usually between 2.0 and 2.6.

• HOAT – Hybrid Organic Acid Technology OAT coolants are typically changed every five years or 50,000 miles, although some automakers specify intervals as long as 10 years or 150,000 miles.

A variety of claims were tested, with years/miles of fluid life performing at the top – a point of difference for Prestone on Universal, North American and Asian formulas. Our enhanced Universal product formulas allows us to also claim “longer engine life guarantee” – another top tested claim that drives purchase.

What colour do you need? Green coolant is the conventional coolant (Ethylene Glycol base) and is the most popularly used coolant. Red coolant typically has a base of Organic Acid Technology which is designed to be more suitable for aluminium radiators.

Prestone® Antifreeze+Coolant prevents corrosion and keeps your radiator performing optimally. Buildup in the engine block cooling channels can make it difficult for coolant to travel. This can cause excessive heat, resulting in oil becoming too hot and thin and potentially damaging the whole system.
