Hürlimann SX

Coolant capacity & service interval

Hürlimann SX coolant capacity is 16 liters. Service intervals include checking every 10 hours and changing every 1200 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • All six Hürlimann SX variants share an identical cooling system capacity of 16 liters, a figure consistent with the demands of high-output agricultural tractor engines where adequate thermal mass is necessary to manage heat loads during sustained field operation.
  • The 10-hour coolant level check interval across the SX 1200, SX 1350, SX 1500, SX 1600, SX 1800, and SX 2000 aligns with a standard daily or near-daily inspection cycle common in professional agricultural equipment, where a single working day in the field can approach or exceed that threshold.
  • The 1200-hour coolant change interval applies uniformly across all six SX variants under normal use conditions. In tractor service, 1200 hours represents a substantial period of accumulated engine runtime, often spanning multiple seasons depending on operational intensity.
  • The SX 1200, SX 1350, and SX 1500 share a production window of 1999-2010, while the SX 1600, SX 1800, and SX 2000 entered production in 2000, one year later, yet all six converge on the same 16-liter capacity and identical service intervals.
  • The uniform 16-liter capacity across models of varying power output, from the SX 1200 through the SX 2000, indicates a shared or closely related engine cooling architecture rather than scaling of the cooling system volume in proportion to engine displacement or rated power.
  • Normal use conditions, as applied to all six rows, typically refer to operation within the parameters the manufacturer considers standard, as opposed to severe conditions such as extreme ambient temperatures, continuous maximum load, or dusty environments that might otherwise warrant shortened intervals.
