What should I check before buying and installing this alternator?

Confirm the vehicle year, engine size and connector/pulley style to ensure fitment. Inspect battery and wiring condition prior to installation—charging issues can stem from corroded terminals or a weak battery rather than the alternator itself.

• Verify year, engine displacement and OEM part number cross-reference
• Confirm belt and pulley condition for proper tension and alignment
• Test battery health and clean electrical connections before swap
• Have tools and torque specs ready or use a professional installer
