Long Service Life

We all want to get our money’s worth when it comes to maintaining our vehicles. You can make the best use of your money by selecting a coolant that’s designed to last. However, It may be costly sometimes but can also improve the vehicle’s fuel efficiency and prevent an array of mechanical issues.

High Boiling Point

Coolants with a high boiling point do a much better job of conducting heat away from the radiator. It’s important to look out for a formula with a high boiling point – at least 250 degrees Fahrenheit. In fact, it is the must-look option while buying a coolant for aluminium radiator.

Antifreeze Protection

Most modern coolants are designed to protect your engine, whatever the weather. They achieve this through the inclusion of antifreeze ingredients. Look for a coolant that can protect your engine at cool temperatures, ideally around -24° F or cold.

Corrosion Resistance

Without anti-corrosion additives, coolants can slowly cause deterioration inside the cooling system. To prevent this, look out for a coolant that’s formulated to reduce corrosion—silicates, phosphates, borates, and more recently, carboxylates, etc.
