Long life coolant is a specialized fluid designed to regulate engine temperature and prevent overheating in vehicles. It is typically composed of a mixture of water and antifreeze, often containing additives that enhance its performance and longevity. This type of coolant is engineered to provide protection against corrosion, scaling, and the formation of sludge within the engine cooling system. Long life coolants can last significantly longer than conventional coolants, often up to five years or more, depending on the formulation and usage conditions.
| Base fluid | Ethylene glycol or propylene glycol |
| Typical lifespan | Up to 5 years or 150,000 miles |
| Freezing point | Typically -34°F to -62°F (-37°C to -52°C) |
| Boiling point | Typically 265°F to 270°F (129°C to 132°C) |
| pH level | Typically between 7.0 and 8.5 |
When selecting long life coolant, consider the specific requirements of your vehicle or equipment, including the manufacturer's recommendations for coolant type and specifications. It's important to specify the desired lifespan, any necessary certifications, and the appropriate freezing and boiling point for your climate. Additionally, inquire about the coolant's compatibility with existing fluids in your system, and determine the quantity needed for your application to ensure optimal performance.
