Application and Buying Notes

The most reliable way to check this starter is by Part No. 1986S00845, then confirming the 12V rating and clockwise rotation suit the vehicle. The listed 2 mounting bores are another important match point, because the physical mounting pattern must align with the engine and housing before the part can be fitted.

For Mercedes-Benz applications, the fitment data points to a wide range of passenger and commercial models, including C-Class, E-Class, S-Class, GLC, GLE, Vito and Sprinter variants. Even so, those model names alone are not enough to confirm compatibility, as the correct starter motor can still depend on engine code, build date and the exact application on the vehicle.

If you are replacing an existing starter, compare the old unit’s Bosch or OEM reference, the mounting style, and the electrical specification. A starter motor is a direct fit component only when the core details line up, so checking the existing part number before purchase is the safest approach.

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 1986S00845 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.

Bosch Starter Motor 12V 13Th CW. Part number 1986S00845 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S00845, 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.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2009, 5-T 2010, 5-T 2011, 5-T 2012, 6-T 2009, 6-T 2010. 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.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility using Part No. 1986S00845, the 12V clockwise specification, the 2 mounting bores, and the exact vehicle application before purchasing.
