Bosch Alternator 12V 90A Foot-mounted Excl. Vacuum Pump Part No. 1986A00588

This Bosch alternator is a 12V, 90A unit supplied as an OE product and identified by part number 1986A00588. It is listed as an alternator passenger type with foot-mounted fastening, which makes the mounting style an important check before ordering.

The alternator is specified as excl. vacuum pump, so it is not a universal replacement for every Bosch or Ford application. Matching the voltage, charge current, mounting style and the vacuum pump arrangement is essential when comparing it against the unit already fitted to the vehicle.

A one-year warranty is supplied, and the item is sold individually as each. Packaging dimensions are 23.9 cm long, 20 cm high and 20 cm wide, which may be useful when planning freight, storage or workshop intake.

For buyers working from the original unit, the most useful identifiers here are Bosch, 12V, 90A and part no. 1986A00588. Those details should be checked against the existing alternator label, the vehicle application, and any mounting or belt-drive differences before purchase.

Application and Buying Notes

The most reliable way to confirm this alternator is by matching part number 1986A00588 with the alternator already fitted to the vehicle. The 12V system voltage, 90A charge current and foot-mounted design need to align with the replacement unit, not just the vehicle badge alone.

The fitment preview includes Ford Fiesta references from 2004 through 2008, but that is not enough on its own to confirm suitability. Final checking should still be done against the part number, mounting style, voltage, amperage and vacuum pump arrangement on the vehicle.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 1986A00588 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.
