Tilt the hood forward to get an excellent view of the 6.2-liter diesel engine. It includes a new water pump, batteries, radiator hoses, transmission mount, solenoid pump, all belts, and all oil and fluids changed. It makes this rugged Hummer a strong runner. And that's exactly what you want in a go-anywhere 4x4. The big torque of the diesel lets you climb mountains, and the tall snorkel let you get deep into the streams. Plus, with a three-speed automatic transmission, power steering, and four-wheel power disc brakes, it's easier than you may think to enjoy one of the toughest pieces of military hardware available.
