Will this alternator fit on a 2007 hummer H3 3.7 liter?
Donte W on Nov 13, 2014
Best Answer: Hello Donte,

Your vehicle is not on this product's Compatibility List, so we cannot confirm fitment. In addition, none of the HUMMER specific units specify your vehicle's details. Therefore, you must contact Mechman for details and solution; 1 (865) 522-6166
