Engine coolant fluid
Contents
Recommendations
Only use OEM Honda Type 2 Blue coolant.
Any other coolant fluid is not applicable for the F20C/F22C engine. Even engine coolant fluids that state "safe for aluminium engines" are still not recommended. The engine coolant fluid has to lubricate the waterpump, work with all the materials used in the cooling system, prevent freezing and at the same time still perform well enough to cool the engine.
The OEM Honda Type 2 Blue coolant comes already pre-mixed with antifreeze to be safe for usage during winter and summer.
