Husqvarna TXC

Coolant capacity & service interval

Husqvarna TXC coolant capacity ranges from 0,9 to 1,3 liters. Service intervals consist of checks every 4 to 5 hours. The data covers 6 configurations.

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

Additional Notes

  • The Husqvarna TXC cooling system capacities across the 2010-2013 range fall into two distinct values: 0.9 liter and a range of 1.1-1.3 liters. The 1.1-1.3 liter figure represents a fill range rather than a fixed volume, which is common in liquid-cooled off-road engines where air pockets during refilling can affect the final settled level.
  • The TXC 450 and TXC 510 share the same 1.1-1.3 liter cooling system capacity and the same 4-hour check interval under normal use conditions, despite differing in displacement.
  • The TXC 250 R and TXC 310 R carry a 5-hour coolant check interval tied to competition use conditions. Competition use typically involves sustained high-load operation, making more frequent fluid checks a standard precaution in that context.
  • The TXC 449 and TXC 511, both covering 2011-2013, share the 0.9 liter cooling system capacity under normal use conditions, with no check interval listed in the specifications for either model.
  • The smaller 0.9 liter capacity found in the TXC 250 R, TXC 310 R, TXC 449, and TXC 511 reflects a more compact cooling circuit relative to the larger-displacement TXC 450 and TXC 510 models, which require the higher 1.1-1.3 liter fill.
  • The TXC 450 and TXC 510 are the only models in the lineup with a defined check interval under normal use, set at 4 hours of operation. Hour-based intervals rather than mileage or calendar-based intervals are standard practice for off-road competition and enduro machines.
