Cooling-system issues account for nearly 40 percent of engine failures. Clearly, it pays to take care of your vehicle’s cooling system.
Sludge are one of the common symptoms of larger problems. Left unchecked, it’ll plug the radiator, heater core or fluid passages, resulting in overheating and expensive repairs.
Low-quality coolants can lead to cooling-system corrosion.
The only way to definitively identify what’s causing sludge in your car radiator is to perform fluid analysis. The report can identify oil, transmission fluid or other contaminants in the engine coolant. Fix any mechanical defects and flush the cooling system. Refill with a high-quality engine coolant.
Let’s start with what kind you should avoid.
You’re no doubt familiar with the conventional “green” engine coolants found at most retailers due to their low price. They contain inorganic salts, such as nitrites, phosphates and silicates.
Inorganic salts deplete quickly – typically in two years or less – and are on the environmental watch list. Once depleted, they are the source of common cooling-system problems, like scale deposits and sludge.
Low-cost “green” engine coolants are the source of several problems, such as sludge/slime and scale deposits.
For these reasons, most vehicle manufacturers have moved away from inorganic salts for newer vehicles.
And so should you.
Instead, use a high-quality coolant that uses organic-acid technology (known as OATs). OATS engine coolants are much more robust and longer-lasting. They virtually eliminate drop-out, scaling and compatibility issues inherent to inorganic salts. This type of engine coolant can be used in a wide variety of applications, even mixing with other coolants as a top-off.
AMSOIL offers three engine coolants, all of which offer a unique blend of organic acids. We use di-acid technology, which means both ends of the organic acid are active. This makes them work faster and form stronger bonds for enhanced protection.
