When replacement is needed

The alternator charges the battery and supplies the vehicle's electrical system; modern vehicles have alternators of 120 to 250 A, an overrunning pulley and control via the engine control unit (LIN). Worn brushes, a faulty regulator, failed diodes or a blocked overrunning clutch lead to the charge warning light, flickering lights, a flat battery or belt noise. Used original alternators by Bosch, Valeo, Denso or Mitsubishi are much cheaper than new parts. Compare amperage, pulley, connector (2-pin, LIN, COM) and the OE number on the housing.

Used or new?

Almost all alternators in our stock are used original parts – tested, with mileage stated where known, and covered by a 12-month warranty. New parts (0 km, usually genuine stock) carry a 24-month warranty. The condition is stated on every item. We do not charge a core deposit on spare parts – that applies only to engines and gearboxes.

How to find the right part

What matters is the OE number (original part number) on your old part – cast in, stamped or on the label. Enter it in the search box above or compare it with the number in our product title; we also list equivalent numbers from other manufacturers (Bosch, Denso, Valeo, Pierburg …) where known. If in doubt, send us your VIN and we will check which part fits.
