Frequently Asked Questions
Will this alternator fit my Isuzu engine without modification?
Yes. This is a direct OEM-fit replacement built to the same Hitachi-type, 12V, 35A specification as the original unit, so no modification is required.
What's included with this part?
You receive the alternator unit only. Mounting hardware and pulleys are not included unless already fitted to the original unit you are replacing.
How can I tell my old alternator has failed?
Common signs include a warning light staying on, dimming or flickering lights, a dead or slowly draining battery, or unusual whining noises from the unit.
What does Hitachi unit mean?
It means this alternator is built to the design and specification of the original Hitachi-manufactured unit fitted to these Isuzu engines, not that it is a genuine Hitachi-branded part.
