Two versatile antifreezes formulated for various applications
We’re pleased to offer two extended life NAPS-free antifreeze/coolants, both formulated for various applications.
The light-duty (LD) formula is designed for domestic and foreign passenger cars and light-duty trucks. A nitrite, amine, phosphate and silicate (NAPS)-free product, our LD Extended Life coolant offers exceptional heat transfer and anti-scaling properties, as well as multi-alloy protection formulation, making it perfect as a universal top-off and service coolant for your fleet of cars and trucks. Organic acid technology (OAT) protects against corrosion of aluminum, brass, cast iron, copper, solder and steel.
The heavy-duty (HD) formula is also versatile and suitable for various applications with heavy duty engines operating on diesel, gasoline, natural gas, propane, LPG or methane-based waste gas. This coolant is also a nitrite, amine, phosphate and silicate (NAPS)-free product, offering multi-alloy protection formulation and compatibility with controlled atmosphere brazed (CAB) aluminum radiators. Service intervals are up to 600,000 miles without the need for supplemental coolant additives (SCAs) or extenders, making this an ideal top-off and service coolant for your mixed fleet.
As you browse our antifreeze selections, look for these features to ensure the safety of your equipment:
- Extended life
- Versatility
- Exceptional heat transfer
- Prevents mineral build up
- NAPS free
- Service intervals
- Light duty vs. heavy duty
We also carry a variety of other lubricants and fluids to keep your vehicles operating optimally:
- Windshield fluid
- Motor oils
- Driveline fluids
- Gear oils
- Greases
Expert Advice
As you choose antifreeze for your fleet of cars and trucks, consider whether the product you need is compatible with other conventional/inorganic additive technology (IAT), hybrid organic acid technology (HOAT), and organic acid technology (OAT) antifreezes/coolants. Also, consider your service intervals – the HD formula goes up to 600,000 miles without the need for extenders or SCAs.
Our antifreeze products are available in 55-gallon drums for convenience and cost efficiency. The LD formula is yellow in color for ease in top offs, while the HD formula is red.
FAQs
Why do I need antifreeze?
Antifreeze /coolant is essential for keeping your car or truck’s engine running smoothly and efficiently. A quality antifreeze will offer the following properties:
Temperature Regulation: Antifreeze helps maintain the engine's temperature by absorbing and dissipating heat. Without it, the engine could overheat or freeze, leading to potential damage.
Preventing Freezing: In cold weather, antifreeze lowers the freezing point of the coolant mixture, preventing it from turning into ice and causing blockages or damage to the engine.
Preventing Boiling: Antifreeze raises the boiling point of the coolant mixture, which helps to prevent it from boiling over during high-temperature conditions and heavy use.
Corrosion Protection: Antifreeze contains additives that help protect the engine and cooling system from rust and corrosion, which can prolong the life of your vehicle's components.
Lubrication: It also lubricates the water pump and other components within the cooling system, reducing friction and wear.
What’s the difference between LD antifreeze and HD antifreeze?
The light-duty formula offers shorter service intervals and is designed for light duty passenger cars and light-duty trucks. The HD coolant was formulated for heavy-duty engines and provides longer service intervals and superior protective properties.
What’s a NAPS-free antifreeze?
NAPS stands for nitrite, amine, phosphate and silicate – and in both formulas 2-ethylhexanoic acid (2-EH)td.
What is organic acid technology (OAT)?
Organic Acid Technology (OAT) is a type of coolant or antifreeze formulation used in many modern vehicles. It differs from traditional coolant formulations in several key ways:
Chemistry: OAT::coolants use organic acids to provide corrosion protection. These organic acids are less reactive and more stable than the inorganic additives used in older coolants. This results in a longer-lasting protective effect for the cooling system components.
Extended Service Life: OAT coolants generally offer a longer service life compared to conventional coolants. They can often go between 5 to 7 years or up to 150,000 miles before needing replacement, whereas traditional coolants might need to be changed more frequently.
Corrosion Protection: OAT coolants are designed to protect against corrosion and cavitation without relying on silicates, which can sometimes cause issues in cooling systems. Instead, they use a combination of organic acids and other additives to form a protective layer on metal surfaces.
Compatibility: OAT coolants are usually designed to be compatible with specific vehicle makes and models. It’s important to use the correct type of coolant for your vehicle, as mixing different types (such as OAT with non-OAT) can reduce the effectiveness of the coolant and potentially harm the cooling system.
Color: OAT coolants are often color-coded to distinguish them from other types of coolants. Common colors include orange, red, or pink, though colors can vary by manufacturer. This helps in identifying and ensuring the correct type of coolant is used.
Environmental Impact: OAT coolants are typically less toxic and have a lower environmental impact compared to some older coolant technologies.
Why is antifreeze colored?
Different colors help differentiate between types of antifreeze and coolant. Various formulations and brands use different colors (like green, orange, or pink) to indicate their specific chemical compositions and intended uses. This can be helpful when checking your vehicle’s manual or ensuring compatibility when adding or replacing coolant.
Why is antifreeze diluted?
Pure antifreeze has a freezing point that is too low and a boiling point that is too high for practical use. Diluting it with water adjusts these properties to achieve an effective freezing and boiling point range for your vehicle's cooling system. Typically, a 50/50 mix of antifreeze and water provides the best balance for most conditions.
