Additional Notes

  • Across all XG-series variants covered in the 2015-2020 span, the Harley-Davidson Street XG cooling system capacity is 1.3 liters, a figure consistent with a relatively compact liquid-cooled motorcycle engine rather than a larger automotive or powersport application.
  • The 1.3-liter figure represents the total cooling system fill volume, meaning the amount of coolant required to fully charge the system during a service or overhaul, not a partial top-off quantity.
  • The XG500 Street 500 carries a 48,000 km coolant change interval under normal use conditions, a schedule that applies equally to both the 2015-2016 and 2017-2020 production spans of that variant.
  • The XG750 Street 750 (2015-2016) and the XG750 Street (2017-2020) share the same 1.3-liter capacity and 48,000 km change interval under normal use, indicating no cooling system specification change between those two production periods for the 750 displacement.
  • The XG750A Street Rod (2017-2020), despite being a distinct trim with a higher-performance orientation compared to the standard Street 750, carries the same 1.3-liter capacity and 48,000 km normal-use interval as the other XG variants.
  • A 48,000 km coolant change interval under normal use conditions is a relatively extended service schedule, reflecting the use of a long-life coolant formulation rather than a conventional short-interval fluid.
