What is the coolant mixture ratio required for the Volvo Penta Freshwater cooling system?

The required coolant mixture ratio for the Volvo Penta Freshwater cooling system is crucial for ensuring optimal engine performance and preventing overheating. A mixture of 40% concentrate coolant and 60% water provides an effective balance that offers sufficient protection against freezing while also maintaining proper engine temperature.

This mixture is designed to maximize the coolant's thermal properties, allowing for efficient heat transfer, which is essential in maintaining engine efficiency during operation. Additionally, the blend helps prevent corrosion and scaling within the cooling system, which can lead to significant issues if not properly managed. Using a mixture of this specific ratio strikes a balance that supports both the reliable operation and longevity of the engine components.
