Additional Notes

  • The Oldsmobile Bravada 4.3 V6 cooling system holds 11.1 liters across the 1991-1995 model years, while the later 4.2-equipped models from 2002-2004 carry a noticeably larger 13.1-liter capacity, reflecting the greater thermal demands of the inline-six engine architecture used in the later generation.
  • The 4.3 V6 from 1991-1995 carries a coolant change interval of 30,000 miles or 24 months under normal use conditions, a relatively short cycle consistent with conventional green coolant formulations that were standard practice in that era.
  • The 4.2-equipped Bravada from 2002-2003 specifies a coolant change interval of 150,000 miles or 60 months under normal use, a significantly extended service life made possible by the Dex-Cool extended-life coolant technology introduced on GM vehicles during that period.
  • The 2004 Bravada 4.2 adds a 12-month coolant check interval to the same 150,000-mile or 60-month change schedule seen in 2002-2003. The periodic check is a separate maintenance action from the full change, allowing condition monitoring without requiring a full system flush at that interval.
  • Both the standard and AWD variants of the Bravada 4.2 share an identical 13.1-liter cooling system capacity for 2002-2003, indicating the drivetrain configuration does not alter the cooling system volume on those models.
  • The 2004 AWD variant mirrors the 2004 standard 4.2 in both capacity and service schedule, carrying the same 13.1-liter fill, the 12-month check, and the 150,000-mile or 60-month change interval under normal use conditions.
