Yes, Granville Zerocol 40 is a concentrate and must be mixed with demineralised or distilled water before use. A 50:50 ratio is standard for optimal performance.
It is not recommended to mix different types of antifreeze. While Zerocol 40 is Si-OAT based, mixing with other technologies (like conventional IAT or HOAT) can reduce its effectiveness and protective properties. Always use as recommended by your vehicle manufacturer.
Granville Zerocol 40 is compatible with and can be used where G40 or GG40 (VW TL 774 J) specifications are recommended, which includes G13. Both are modern Si-OAT coolants offering excellent protection.
Consult your vehicle manufacturer's service manual for the recommended coolant change interval. As a long-life coolant, Zerocol 40 typically offers extended service intervals compared to older coolant types.
Si-OAT stands for Silicate Organic Acid Technology. This advanced formula combines the fast-acting protection of silicates with the long-lasting, environmentally friendly corrosion inhibition of Organic Acid Technology, offering superior performance and extended life.
No, always use demineralised or distilled water. Tap water contains minerals that can cause scale deposits and interfere with the coolant's performance and protective additives.
A 50% mixture of Granville Zerocol 40 concentrate and distilled water provides freeze protection down to -36°C (-33°F).
Check for leaks in hoses, radiator, water pump, or head gasket. A significant drop can indicate a serious cooling system fault.
Ensure the coolant concentration is correct, the system is properly bled of air, and the thermostat and radiator fan are functioning correctly. Check for blockages in the radiator or hoses.
Indicates the coolant may be old or the wrong type was used. A full system flush and refill with the correct Granville Zerocol 40 mixture is recommended.
Confirm the dilution ratio used. If compromised, drain, flush, and refill with a correctly mixed 50:50 solution of Zerocol 40 and distilled water.
