  • Use: Normal
  • Capacity 9,9-10 liter
  • Change 150000 miles/ 60 months

Additional Notes

  • The Pontiac Torrent 3.4 V6 cooling system holds 9.9 to 10 liters of coolant, while the 3.6 V6 variant requires a noticeably larger fill of 10.4 to 11.1 liters, reflecting the greater displacement and associated thermal management demands of the larger engine.
  • The 3.6 V6 cooling system capacity is listed as a range of 10.4 to 11.1 liters, which is wider than the 3.4 V6 range of 9.9 to 10 liters. A capacity range rather than a fixed value typically accounts for variables such as residual fluid retention during a drain or minor differences in system configuration.
  • Both engine configurations share an identical coolant change interval of 150,000 miles or 60 months under normal use conditions, meaning the service schedule does not differ between the 3.4 V6 and the 3.6 V6 despite their differing system capacities.
  • A 60-month interval translates to a five-year service cycle, which is consistent with long-life coolant formulations such as DEX-COOL, commonly specified for GM vehicles of this era. The mileage threshold of 150,000 miles would be reached before the time limit for higher-mileage drivers.
  • The 3.6 V6 engine was introduced in the Torrent lineup for the 2007 model year, meaning the 3.4 V6 specifications covering 2005-2009 represent the full production span, while the 3.6 V6 specifications apply only to the 2007-2009 model years.
