What should I check before installing this alternator?

Before installation, verify the part number, pulley groove count, rotation direction and electrical connector type on your original alternator. Also inspect the battery, belt condition, and ground connections to ensure the charging system functions properly once the new unit is installed.

• Compare your OE part number to 37300-2G061 or listed cross-references
