Questions & Answers
Is this a genuine original part?
No – it is a brand new aftermarket replacement built to OE specification.
Will it fit a 12V Isuzu D-Max or other 12V vehicle?
No. This is a 24V unit for heavy machinery; it will not work on a 12V system.
How do I check fitment?
Compare the part number on your original alternator with the cross-reference list above, and check the 7-groove pulley, clockwise rotation and 3 mounting points. If in doubt, send us the number or a photo of your old unit before ordering.
