Used Hummer Engines

Yes, LS swaps are very possible but will need custom mounts, wiring, ECU tuning, and some work on the transmission. This is a very popular swap but fairly labor-intensive here in the U.S.

Avoid the 2003 and early 2004 H2 engines because they gave common problems with the 6.0L V8- oil consumption, sensor failures, etc. Later versions were better engineered and, hence, more reliable.

On a used Hummer engine, anything over 150,000 miles will be considered a high mileage. That being said, a number of engines exceed 200K miles of driving with the right maintainance.

The H2's V8 engine- either 6.0L or 6.2L- is the more powerful one and monger will definitely tend to outlast the inline-5 of the H3, whereas H3s will be cheaper to own with better fuel efficiency. So decide if you want more power or lower cost of ownership.

Hammer H3 is powered by a 3.5-liter or 3.7-liter inline-5 petrol engine, depending on the year. The initial model (2005–2006) came up with a 3.5L inline-5 engine, producing 242 horsepower and 242 lb fees. The latter models, including 2007, found an upgraded 3.7L inline -5 engine, which improved a slightly more power and torque, performance. These engines are naturally hopeful, which means they depend on atmospheric pressure rather than forced induction. Inline -5 configuration SUV is somewhat rare, providing a unique balance between medium -sized H3 -friendly power, efficiency and off -road capacity.

Lobster H1 is equipped with multiple engine options during production, the most famous 6.5-liter Detroit Diesel Turboladed V8 engine, which is known for credibility in its high torque and hard terrain conditions. Petrol engine options included 5.7-liter and 6.6-liter V8s, giving strong power, but usually less torque than the diesel version. These engines were designed to provide durability and robust performance, reflecting the military origin of H1 and civilian use in the extreme region and civilian use in heavy off-roading.

Our H2 is usually powered by a 6.0-liter V8 petrol engine known as the Vortec 6000. This engine produces around 325 horsepower and 365 lb-ft, providing H2 to strong terrain and Toking skills. The H2 model was later upgraded to the 6.2-liter V8 engine, which increases production approximately 393 horsepower and 415 lb-ft torque. Both engines are naturally hopeful and are based on the small and blocking V8 architecture of General Motors, which balances strength and reliability for this large SUV.

Repetition of the engine head in 2007 hummer H3 usually occurs between $300 and $ 2000, depending on the number of workshops, location and injury. This process includes removing the cylinder head, cleaning, inspecting for cracks or wars, restarting intercourse surfaces, and if necessary valves, valve guides and seals repair or replace or replace. If the head is seriously damaged or torn, further machining or replacement may be required, costs increase. The work frequency varies widely, with dealers who are usually more cost than independent stores. Given 3.5L or 3.7L -inline -5 engine, the availability of parts is decent, but somewhat specific. Overall, it is intelligent to receive a wide offer before continuing to secure the work, which fits the budget and provides a guarantee of store reconciliation.
