How do I verify this alternator fits my car?

Confirm compatibility by matching your vehicle year, make, model, engine size, and the original alternator part number. YYHHZZ lists common replacement numbers to cross-check against the one on your current alternator.

What electrical and mechanical specs should I expect?

The alternator delivers nominal 12.0 volts and a rated output of 110 amps, matching typical OEM charging needs for the specified engines. Mechanical fit features like pulley groove count and rotation direction are matched so the belt and mounting align with factory setup.

• Rated output: 110 amps at 12.0 volts.

How difficult is installation and what should I prepare?

Installation is similar to other alternator swaps—remove the battery negative, loosen the belt, detach electrical connections, unbolt the old unit, and reverse the steps with the new alternator. Basic hand tools and a torque wrench are usually sufficient; professional installation is recommended if you lack experience working on charging systems.

• Transfer mounting bolts and electrical connectors to the new alternator.
• Verify output and belt alignment after installation.
