Application and Buying Notes

Before ordering, compare the existing alternator against Part No. 1986A00952, the 12V system rating and the 180A charge current. These are the most useful checkpoints for a replacement alternator, especially where the vehicle may have more than one charging system option.

Bosch recommends considering V-Belt or V-Ribbed Belt as an additional repair item when fitting the alternator. That is practical advice where belt wear, noise or age may affect the charging system after installation.

The listed warranty is 12 months, which gives a clear reference for the purchased component. Packaging dimensions are 24 x 18.5 x 20, which may be useful for workshop handling or freight planning, but they do not confirm vehicle fitment.

For Mercedes-Benz applications shown in the fitment data, use the exact model designation and year reference together with the part number. Even within a model range, charging system variations can differ, so the safest approach is to match the part number and alternator style first.

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 1986A00952 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator passenger in workshop, fleet, trade, agricultural, or construction service, the listed output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MERCEDES-BENZ CLS, MERCEDES-BENZ CLS 2005, MERCEDES-BENZ CLS 2006, MERCEDES-BENZ CLS 2007. 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.

Compatibility note: Confirm fitment by matching Part No. 1986A00952, 12V, 180A, direct fastening, and excl. vacuum pump against the removed alternator and vehicle application details before purchase.
