Bosch Alternator 12V 200A 1986A00951

The Bosch Alternator 12V 200A is a rotating electrical component supplied as part number 1986A00951. It is listed as an alternator type excl. vacuum pump, with a 200 amp charge current and direct fastening fitment. For buyers replacing a charging component, those details matter as much as the brand name because the alternator design and mounting style must match the vehicle application.

This unit carries a 12 month warranty and is sold as each. It is described as made from high quality raw materials, corrosion resistant, and fitted with a reduction drive to maintain continual speeds for easier starting. Those are practical points to check when comparing replacement alternators, particularly where the original part has to cope with regular use and difficult operating conditions.

The recommended additional repair is the V-Belt/V-Ribbed Belt, which is worth planning for when replacing an alternator. If the drive belt is worn, glazed, or contaminated, fitting a new alternator without addressing the belt can leave the charging system under the same strain. Matching the alternator specification and checking the belt condition together is the sensible approach.

Fitment information supplied for this Bosch alternator points to selected Mercedes-Benz applications, including Valente, Viano, and Vito / Mixto variants. The safest way to confirm suitability is to compare the part number 1986A00951, the 12V 200A rating, and the alternator type excl. vacuum pump against the vehicle details before ordering.
