Maserati Quattroporte, AM 107

Additional Notes

• The Maserati Quattroporte AM 107 carries a coolant capacity of 15 liters across all listed configurations, a figure consistent with large-displacement Italian grand touring engines of the 1960s that relied on substantial coolant volume to manage heat across extended high-speed driving.
• Both the 4200 and 4700 engine variants share an identical 15-liter cooling system capacity, meaning no displacement-related difference exists between the two engine families in terms of coolant fill volume.
• The 4200 variant, designated AM 107, maintains the 15-liter capacity across the 1963-1967 and 1968-1970 model year splits, indicating no change in cooling system volume between the two production periods.
• The 4700 variant, designated AM 107/4700, likewise holds a consistent 15-liter capacity across both the 1963-1967 and 1968-1970 periods, mirroring the pattern seen in the smaller-displacement sibling.
• All four configurations are rated under normal use conditions, which in coolant service contexts typically refers to standard operating environments without the additional thermal stress associated with severe-duty or high-load classifications.
• A 15-liter cooling system capacity is notably high relative to many contemporary vehicles, reflecting the demands placed on the cooling circuit by the Quattroporte's V8 architecture and the relatively large engine bay volumes characteristic of full-size luxury saloons of the era.
