    Yes, that will be more than enough. The cooling capacity is about 5 litres. You have 3 litres of G12+ which would give you a 60% mix (this is assuming the system is completely dry before filling. If there is residual coolant in the block or heat exchanger, then the mix will be more that 60% G12+"

    Mixture should be at least 40%, but no higher than 60% as boiling protection is reduced.

    I would mix your G12+ with water to 40% in a separate container and then add it to the engine. You know you will have the correct mix then.

    “G12+” (40 %) and water (60 %) for frost protection to –25 °C.
    “G12+” (50 %) and water (50 %) for frost protection to –35 °C.
    “G12+” (60 %) and water (40 %) for frost protection to –40 °C.

    No need to drain. Just mix up the desired percentage of coolant to water into a separate container. Then pour in. You know the mix is correct then. If you have any left over, just store it for top up if required at a later date.
    It will take less than 5 litres. I would mix up one bottle with water then see how you go.
