Additional Notes
- The Morgan Plus Six 3.0 (250 kW) cooling system is split into two separate circuits, with the high temperature cooling circuit holding 9.8 liters and the low temperature cooling circuit holding 4.2 liters.
- The combined coolant volume across both circuits totals 14.0 liters, which reflects the dual-circuit architecture of the 3.0-liter engine rather than a single unified cooling loop.
- The 4.2-liter low temperature cooling circuit is a notably smaller volume compared to the 9.8-liter high temperature circuit, consistent with its role in managing charge air or ancillary thermal loads rather than primary engine cooling.
- Under normal use conditions, the coolant change interval is set at 50,000 miles or 60 months, whichever comes first, applying to the 2019 model year onward.
- A 60-month service interval for coolant is equivalent to five years, which places the Plus Six 3.0 within a long-life coolant servicing schedule typical of modern extended-life antifreeze formulations.
