An engine coolant keeps your engine within a specific operating temperature range, which keeps it from overheating and resulting in malfunctions. It is made from either ethylene glycol or propylene, water, and some protection additives. A coolant is essential as the synergy between glycols and water enable it to perform in cold and hot environments, all year round. The extra additives present in a coolant also provides protection against corrosion. Supergen’s engine coolant is the perfect solution to keep your engine in a state of top-notch conditions!
