Additional Notes
- The Iseki TK 527 F, TK 532 F, TK 538 F, and TK 538 FH all share an identical cooling system capacity of 6.5 liters, indicating a common engine cooling architecture across those four variants.
- The TK 546 carries a notably larger cooling system capacity of 10.5 liters, which is 4 liters more than the 6.5-liter figure seen in the other four models, reflecting a more substantial engine cooling requirement for that variant.
- A 10.5-liter cooling system capacity, as found in the TK 546, is consistent with a larger displacement or higher-output engine that generates more heat and therefore demands greater coolant volume to maintain operating temperatures.
- Across all five variants, the coolant check interval is set at every 10 operating hours under normal use conditions, a relatively frequent interval typical of compact utility tractors operating in demanding field environments.
- The coolant change interval is specified at 12 months for all five variants under normal use conditions, meaning the service schedule is time-based rather than tied to accumulated operating hours.
- A time-based change interval of 12 months, as applied here, accounts for coolant degradation from oxidation and additive depletion that occurs regardless of how many hours the machine has been run.
- All five models carry a starting year of 1998, meaning the cooling system specifications listed apply from that model year onward for each respective variant.
