SYM HD Evo, LH

Coolant capacity & service interval

SYM HD Evo and LH models require coolant with a capacity range of 0.5 to 0.6 liters. Service intervals require a change every 12 months. The data covers 2 configurations.

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

TypeSpecifications
HD Evo 125, LH12W (2004-2011)
  • Use: Normal
  • Between min and max.
  • Change 12 months
HD Evo 200, LH18W (2004-2011)
  • Use: Normal
  • Between min and max.
  • Change 12 months

Additional Notes

  • The SYM HD Evo LH12W and LH18W share the same coolant service interval of 12 months under normal use conditions.
  • Rather than a fixed volume figure, the coolant fill level for both the 125 and 200 displacement variants is defined by the range between the minimum and maximum marks on the reservoir, which is a standard approach for cooling system maintenance fills rather than full system overhauls.
  • The 12-month change interval applies consistently across both the LH12W and LH18W configurations for the 2004-2011 model years, with no variation tied to engine displacement.
