Correct answer
Specification, concentration and freeze protection for those temperatures.
Check that it is the specified coolant and provides enough freeze protection for expected temperatures at the manufacturer’s concentration. Do not replace the mixture with ordinary water or indiscriminately add antifreeze to a correctly prepared product. Ready-to-use products and concentrates have different procedures; do not mix incompatible products. Check or top up with the system cold as instructed and do not open a hot pressurised circuit.
