Hummer H3 Parts

The Hummer H3 is an off-road vehicle introduced in 2006, and, compared to the H2, the model is 16.9 inches (429 mm) shorter, 6 inches (152 mm) shorter, and 6.5 inches (165 mm) narrower. While the interior no longer has the same wide center console, instead it has a two- or three-seat front layout with an extra seat in the middle. It was equipped with a 3.5 liter straight-5 cylinder engine that produced 220 hp (160 kW) and 225 lb. ft. (305 Nm) of torque accompanied by a standard five-speed Aisin AR5 manual transmission and also offers an optional Hydra-Matic 4L60-E four-speed automatic transmission. Such engine was replaced by a 3.7-liter LLR, which produced 242 hp (180 kW) and 242 lb. ft. (328 Nm) of torque and statistics were revised to 239 hp (178 kW) and 241 lb. ft. (327 Nm). For its off-road performance, it H3 is equipped with a two-speed, electronically controlled full-time four-wheel-drive system, letting the vehicle move at a speed of 5mph in 27 inches of water and 20mph in 20 inches of water. It also has a cargo that could be expanded when the rear seats are folded down.

Maintaining your Hummer H3 in peak condition requires vigilance and an understanding of common issues. Long-term engine operation can degrade performance, with symptoms like poor fuel efficiency, hesitation during acceleration, and difficulty starting, often signaled by loud knocking sounds or an illuminated Check Engine Light. Regularly inspect the air filter, intake manifold gasket, drive belt, and cylinder head gasket to prevent these issues. The H3, being a modern model, also houses many electrical components susceptible to wear and tear. Known weak points include the fuel pressure regulator, which can lead to faulty AC auto mode, inconsistent cooling, and incorrect outdoor temperature readings, and the window regulator, which, if faulty, necessitates multiple button presses to roll the window up or down and produces clicking sounds from the door. Proactive maintenance, such as replacing the windshield wiper at least once a year, ensures clear visibility and reduces accident risk. Regular attention to the cabin air filter, fog lights, headlights, and wheel seals also contributes to safe and comfortable driving.
