Additional Notes
- The Holder C 50 Turbo, C 500, and C 65 Turbo all share an identical cooling system capacity of 9 liters, indicating a uniform system volume across the lineup despite differences in engine configuration.
- A 9-liter cooling system capacity is a moderately sized fill for compact utility and tractor-class machinery, reflecting the demands of liquid-cooled diesel engines in this segment.
- The C 50 Turbo covers model years 1983-1990, the C 500 covers 1982-1990, and the C 65 Turbo covers 1986-1990, meaning the C 500 has the earliest production start date among the three variants listed.
- All three variants carry a 12-month coolant change interval under normal use conditions, meaning the service schedule is tied to calendar time rather than operating hours or mileage.
- A 12-month interval under normal use is a standard annual replacement cycle, commonly applied to coolant formulations that degrade through oxidation and additive depletion over time regardless of machine activity level.
