How these references affect your decision

Two separately documented hybrid cooling systems

The Axio Hybrid NKE165 manual has distinct engine and inverter coolant reference quantities; engine capacity varies with cold-climate specification.

Do not merge these circuits or infer a complete flush quantity from their capacities.
