Chang'an Yuexiang

Coolant capacity & service interval

Chang'an Yuexiang coolant capacity ranges from 4,7 to 7,3 liters. Service intervals include checks at 5000 km or 3 months and 10000 km or 6 months, with changes at 20000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The Chang'an Yuexiang V3 SC7134 cooling system carries a capacity range of 4.7 to 5.3 liters, which reflects a variable fill volume rather than a single fixed figure, a characteristic sometimes associated with air purging tolerances during refill procedures.
  • The Yuexiang V7 SC7134 cooling system holds a fixed capacity of 7.3 liters, a notably larger volume compared to the V3's range, consistent with the greater engine displacement or cooling circuit size of the V7 platform.
  • Both the V3 and V7 share the same normal-use coolant change interval of 20,000 km or 12 months, whichever comes first, placing routine coolant replacement on an annual or distance-based cycle under standard operating conditions.
  • The coolant check interval for both the V3 and V7 under normal use is set at 10,000 km or 6 months, meaning the system is inspected at twice the frequency of a full change.
  • The V7 SC7134 carries a separate initial service specification, with a check interval of 5,000 km or 3 months, which is half the distance and half the time of the standard normal-use check interval applied to the same model.
  • The initial service check interval for the V7 applies to a 7.3-liter cooling system, meaning a relatively large volume of coolant is subject to early inspection before the standard maintenance schedule takes over.
