It is listed as an alternator type excl. vacuum pump, so the fit must be checked against the vehicle’s original alternator arrangement before purchase.\u003c\/p\u003e\n\u003cp\u003eThis unit uses a double pivot lever fastening type and the recommended related repair is a V-Belt\/V-Ribbed Belt. Those details matter because the alternator mounting style and belt setup need to match the vehicle application, especially where the original charging system has been removed or replaced before.\u003c\/p\u003e\n\u003cp\u003eBosch notes this alternator is manufactured to the same rigorous production standard as OE parts, with high tech regulators and rectifiers to help protect onboard electrical systems. It is manufactured in Spain and carries a 12 month warranty, which gives a useful reference point for buyers comparing replacement options for a 190A charging system.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator with 190A charge current\u003c\/li\u003e\n\u003cli\u003eBosch part number 1986A01057\u003c\/li\u003e\n\u003cli\u003eAlternator type: excl. vacuum pump\u003c\/li\u003e\n\u003cli\u003eDouble pivot lever fastening type\u003c\/li\u003e\n\u003cli\u003eManufactured in Spain\u003c\/li\u003e\n\u003cli\u003e12 month warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Bosch\u003c\/li\u003e\n\u003cli\u003eProduct type: Alternator\u003c\/li\u003e\n\u003cli\u003eVoltage: 12\u003c\/li\u003e\n\u003cli\u003ePower rating: 190 amp\u003c\/li\u003e\n\u003cli\u003eAlternator charge current: 190 A\u003c\/li\u003e\n\u003cli\u003eUnit of measure: Each\u003c\/li\u003e\n\u003cli\u003eManufactured in: Spain\u003c\/li\u003e\n\u003cli\u003ePackaging dimensions: 23.9 x 20 x 20\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment guidance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eListed fitment groups include Mercedes-Benz C-Class, Mercedes-Benz E-Class and Mercedes-Benz GLC.\u003c\/li\u003e\n\u003cli\u003eSupported fitment references include Mercedes-Benz C-Class 2013, 2014, 2015, 2016, 2017, 2018 and 2019.\u003c\/li\u003e\n\u003cli\u003eSupported fitment references include Mercedes-Benz E-Class 2016, 2017 and 2018.\u003c\/li\u003e\n\u003cli\u003eFitment is only relevant where the vehicle uses a 12V alternator with the same mounting style and an alternator type excl. vacuum pump.\u003c\/li\u003e\n\u003cli\u003eThe part number 1986A01057 should be checked against the vehicle application before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eThe important checks on this Bosch 12V 190A alternator are the part number 1986A01057, the alternator type excl. vacuum pump, and the double pivot lever fastening type. If any of those details differ from the vehicle’s original unit, the part should not be assumed to fit, even if the vehicle is within a listed Mercedes-Benz model family.\u003c\/p\u003e\n\u003cp\u003eThe 190 amp charge current is a significant specification and is suited to applications that were originally built around that output. Do not select an alternator by vehicle badge alone. Match the original charging specification, the mounting style, and the belt arrangement, including the recommended V-Belt\/V-Ribbed Belt repair consideration.\u003c\/p\u003e\n\u003cp\u003eWhen replacing an alternator, it is sensible to inspect the related charging system parts at the same time. Bosch recommends additional repair attention to the belt side of the system, and the unit’s regulators and rectifiers are intended to help protect onboard electrical systems. Care with installation, belt condition and the vehicle’s original electrical setup remains important for a reliable result.\u003c\/p\u003e\n\u003cp\u003ePackaging dimensions are 23.9 x 20 x 20, and the unit is supplied each. That can help when planning freight, storage or workshop handling, but the main buying decision still comes back to vehicle application, mounting design and the exact Bosch part number 1986A01057.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 1986A01057 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 12 Months, Voltage 12, Fastening Type Double Pivot Lever, Recommended additional repairs V-Belt\/V-Ribbed Belt, Packaging width 20, Manufactured in Spain, Product Group 1 ROTATING ELECTRICAL, Part No. 1986A01057.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Brand BOSCH, Description Bosch Alternator 12V 190A, Power Rating (Amp) 190, Alternator Charge Current [A] 190, Alternator Type excl. vacuum pump, Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 190A. Part number 1986A01057 should be checked first. Listed voltage is 12. Listed output rating is 190. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 1986A01057, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 190 should be checked carefully.
