Additional Notes
- The Hummer H2 SUT 6.0 V8 carries a cooling system capacity of 16.3 liters, which is 0.5 liters more than the 15.8-liter capacity shared by both 6.2 V8 configurations.
- The 15.8-liter cooling system capacity on the 6.2 V8 applies equally to the standard and Flex-power variants produced from 2008-2010, indicating no capacity difference between those two configurations.
- All three configurations share a coolant check interval of every 12,500 km or 6 months, whichever comes first, under normal use conditions.
- The coolant change interval across all configurations is 240,000 km or 60 months under normal use conditions, with 60 months equating to a 5-year service cycle.
- A 240,000 km change interval is characteristic of extended-life coolant formulations, which are engineered to resist degradation of corrosion inhibitors over long service periods compared to conventional coolants.
- The 6.0 V8 was produced from 2003-2007, while the 6.2 V8 entered production in 2007, meaning both engines were available during the 2007 model year.
- The Flex-power designation on the 6.2 V8 from 2008-2010 refers to a multi-fuel capable engine, yet the cooling system capacity and service intervals remain identical to the standard 6.2 V8.
