The GM Hummer H2, produced from 2003 to 2007, was a powerful and imposing SUV that epitomized the "go-anywhere" spirit of the Hummer brand. Built on a GM GMT800 platform, it shared its underpinnings with other large SUVs like the Chevrolet Silverado and GMC Sierra. Under the hood, the H2 was powered by a robust 6.0L Vortec V8 engine, capable of producing 316 horsepower and 360 lb-ft of torque. This engine was coupled with a four-speed automatic transmission, allowing the H2 to navigate challenging terrain with ease. The H2 was renowned for its distinctive styling, featuring a boxy exterior with a high ground clearance, large wheels, and a prominent grille. The interior, while rugged, offered a surprising level of comfort and features, with available leather upholstery, a Bose sound system, and a rear-seat entertainment system.

Despite its off-road prowess and commanding presence, the Hummer H2 faced criticism for its fuel consumption and environmental impact. Its massive proportions and heavy engine contributed to its thirst for gasoline, and its overall lack of fuel efficiency made it a less appealing option in the face of rising gas prices and growing environmental concerns. Additionally, its production ended in 2007 as GM shifted its focus towards more fuel-efficient models. However, the Hummer H2 remains a symbol of American automotive brawn and continues to be appreciated by enthusiasts for its off-road capabilities and distinctive aesthetic. The Service Repair Manual for the 2003-2007 Hummer H2 is a comprehensive guide for mechanics and owners alike, providing detailed instructions and diagrams for troubleshooting, repairing, and maintaining these complex vehicles.
