Those details are the main cues for whether the unit suits the vehicle and accessories already fitted.\u003c\/p\u003e\n\u003cp\u003eBecause this alternator is listed as excl. vacuum pump, it should only be considered where that configuration matches the original unit. If the vehicle uses a different alternator style, pulley count, or mounting arrangement, the unit may not be suitable even if the Bosch brand and voltage seem close.\u003c\/p\u003e\n\u003cp\u003eThe pulley diameter is listed at 57mm and the pulley is described as a multi-belt type. That makes belt alignment and belt condition worth checking at the same time, especially since recommended additional repairs include V-Belt\/V-Ribbed Belt replacement where needed.\u003c\/p\u003e\n\u003cp\u003eBosch lists this as a new alternator with an internal regulator and corrosion resistant construction. Those are useful fitment and service details, but they do not replace a direct application check. When in doubt, compare the old unit side-by-side with the listing details before fitting.\u003c\/p\u003e\n\u003cp\u003eIf you are matching an existing Bosch unit, the brand reference, part number, and pin code IR189 can help narrow the search. Even so, the final check should always be the complete specification set, because alternators can differ in mounting, pulley arrangement, and internal configuration.\u003c\/p\u003e\n\u003cp\u003eFor workshop or trade use, the packaging dimensions and one year warranty are practical points to note, but the important buying decision is still compatibility. A correct electrical rating alone is not enough if the alternator mount, pulley, or rotation does not align with the vehicle.\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 0124425112 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 One Year, Power Rating (Amp) 120, Pulley Section 5 Groove, Rotation CW, Voltage 12, New \/ Reman.

Part number 0124425112 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Pad. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number 0124425112, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include ALFA ROMEO 159, ALFA ROMEO 159 2006, ALFA ROMEO 159 2007, ALFA ROMEO 159 2008. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm fitment using Bosch part number 0124425112, the 12V 120A specification, and the listed mounting and pulley details before purchase. Do not rely on brand alone, and do not assume fitment without checking the vehicle application and the existing alternator configuration.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the part number for this alternator?\u003c\/h4\u003e\n\u003cp\u003eThe Bosch part number listed is 0124425112.\u003c\/p\u003e\n\u003ch4\u003eWhat voltage and output does it have?\u003c\/h4\u003e\n\u003cp\u003eIt is a 12V alternator with a 120A charge current.\u003c\/p\u003e\n\u003ch4\u003eIs this alternator new or remanufactured?\u003c\/h4\u003e\n\u003cp\u003eIt is listed as new.\u003c\/p\u003e\n\u003ch4\u003eWhat pulley setup does it use?\u003c\/h4\u003e\n\u003cp\u003eIt has a 5 groove multi-belt pulley with a 57mm outside diameter.\u003c\/p\u003e\n\u003ch4\u003eDoes it have an internal regulator?\u003c\/h4\u003e\n\u003cp\u003eYes.
