Repair manuals
The H2 (2003 to 2009) is a full-size off-road SUV and SUT built on GM's heavy-duty truck chassis. It uses a 6.0-liter V8, and from 2008 a 6.2-liter V8 with a 6-speed automatic.
Our H2 manuals cover the V8s, the transmissions, the full-time 4WD system and locking rear differential, air suspension and complete wiring diagrams.
