Before you order

Fitment & setup

What should I compare before choosing this alternator?

Check the existing part number, mounting, pulley/belt arrangement and electrical plug. Send those details and the engine identification to GT40; the engine brand alone is not enough to confirm the replacement.

Will an adapter plug be required?

The listing identifies a WH7SI adapter plug when replacing API 20054 or 20054-HO. Ask GT40 to confirm whether that adapter applies to your installation and whether it must be supplied separately.
