Additional Notes

  • The Subaru Tribeca (B9) cooling system capacity for the 2006-2008 B9 Tribeca is listed at 7.4 liters, which is slightly lower than the 7.6 liters specified for all subsequent model configurations from 2008 onward.
  • The 7.6-liter cooling system capacity applies across the 2008-2009, 2009-2011, and 2011-2014 Tribeca configurations, representing the majority of the model's production span.
  • Under normal use conditions, the coolant change interval is set at 75,000 miles or 72 months across all configurations, regardless of the capacity difference between the 2006-2008 and later models.
  • The initial service use condition carries a significantly extended change interval of 137,500 miles or 132 months, compared to the 75,000-mile or 72-month interval under normal use. This extended interval reflects the longer service life of the factory-fill coolant formulation.
  • A coolant level check interval of 30,000 miles or 30 months is specified for the 2006-2008 B9 Tribeca under normal use, and the same check interval reappears for the 2009-2011 and 2011-2014 configurations. The 2008-2009 configuration does not carry a listed check interval under either use condition.
  • The initial service change interval of 132 months equates to 11 years, meaning the factory-fill coolant in a Tribeca is rated to remain in service for a considerably longer period before the first scheduled change compared to subsequent refills.
  • After the initial service change, the coolant reverts to the normal use interval of 75,000 miles or 72 months for all subsequent changes, establishing a two-tier interval structure across the full service life of the cooling system.
