Husaberg FC

Coolant capacity & service interval

Husaberg FC coolant capacity is 1,3 liters. Service intervals are 100 hours or 12 months. The data covers 4 configurations.

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

Type	Specifications
FC 450 e (2003-2003)	Use: Normal Capacity 1,3 liter Change 100 hours/ 12 months
FC 450/6 (2003-2003)	Use: Normal Capacity 1,3 liter Change 100 hours/ 12 months
FC 550/4 (2003-2005)	Use: Normal Capacity 1,3 liter Change 100 hours/ 12 months
FC 550/6 (2001-2003)	Use: Normal Capacity 1,3 liter Change 100 hours/ 12 months

All four FC variants listed across the 2001-2005 period share a uniform cooling system capacity of 1.3 liters, indicating a consistent cooling circuit volume across both the 450 and 550 engine displacements.
The 1.3-liter figure represents a service fill capacity, meaning the amount of coolant required when refilling the system during routine maintenance rather than a full overhaul or dry-build specification.
The change interval of 100 hours or 12 months, whichever comes first, applies under normal use conditions across all listed variants. The dual-trigger format is common in off-road motorsport equipment, where engine hours can accumulate rapidly regardless of calendar time.
The Husaberg FC 450 e and FC 450/6 both cover the 2003 model year and carry identical cooling system specifications, despite the differing designations suggesting distinct configurations within the 450 displacement class.
The FC 550/4 spans 2003-2005, the widest model year range among the listed variants, yet retains the same 1.3-liter capacity and 100-hour/12-month interval as the earlier FC 550/6, which covered 2001-2003.
A 100-hour service interval is a relatively short cycle by general automotive standards, reflecting the high thermal and mechanical stress typical of competition-oriented four-stroke motocross engines, where coolant degrades more quickly due to sustained high operating temperatures.
