Additional Notes

  • All three configurations of the Hummer H2 (USA / CAN) share an identical transfer case fluid capacity of 1.4 liters, which represents a service fill volume for the transfer box rather than a full overhaul or dry-fill quantity.
  • The 6.0 V8, covering model years 2002-2007, carries a fluid change interval of 83,000 km under normal use conditions, placing it slightly above the 80,000 km interval specified for both 6.2 V8 configurations.
  • The 6.2 V8 and 6.2 V8 Flex-power variants, spanning 2007-2010 and 2008-2010 respectively, share an identical change interval of 80,000 km under normal use conditions, despite differing in fuel system design.
  • A fluid check interval of 12 months is specified exclusively for the 6.0 V8 (2002-2007) under normal use conditions. Neither the 6.2 V8 nor the 6.2 V8 Flex-power rows carry a corresponding check interval in the specifications.
  • The 6.2 V8 Flex-power configuration, introduced for 2008-2010, carries the same transfer case fluid capacity and change interval as the standard 6.2 V8, indicating no differentiation in transfer case servicing between the two engine variants despite the flex-fuel capability.
