Lindner Unitrac

Coolant capacity & service interval

Lindner Unitrac coolant capacity ranges from 17 to 23 liters. Service intervals include checks at 250 hours and changes at 1000 hours. The data covers 3 configurations.

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

Additional Notes

  • The Lindner Unitrac 68 and Unitrac 78 share an identical cooling system capacity of 17 liters, indicating the two models use the same engine cooling architecture despite differing model designations.
  • The Unitrac 95 carries a noticeably larger cooling system capacity of 23 liters, reflecting a more substantial engine cooling requirement compared to the 17-liter figure seen in the lower-numbered variants.
  • Across all three Unitrac configurations, the coolant check interval is set at 250 hours under normal use conditions, representing a periodic inspection point rather than a full fluid exchange.
  • The coolant change interval for the Unitrac 68, Unitrac 78, and Unitrac 95 is uniformly specified at 1000 hours under normal use conditions, meaning a full drain and refill of the cooling system is due at that operating hour threshold.
  • The gap between the 250-hour check interval and the 1000-hour change interval means the cooling system on each of the three Unitrac variants is inspected three times before a full fluid replacement is due.
  • All three configurations carry a starting year of 2004, meaning the 17-liter and 23-liter capacity specifications, along with the 250-hour and 1000-hour service intervals, have applied since that model year.
