Application and Buying Notes

Before ordering, match the part number MG252 and OEM number 11201990 against the alternator already fitted to the vehicle. The mounting layout matters here: this unit is a twin leg alternator with 60mm inside mounting legs, 60.0mm mounting bores distance, and a 147mm mount centre to centre.

The electrical setup should also be checked carefully. This alternator is 12V with a 90A charge current, an internal regulator, and pin code IR175, so the existing charging system arrangement needs to align with those details rather than relying on appearance alone.

The pulley and belt arrangement are equally important. This unit uses a 6 groove V-ribbed belt pulley, has a 50mm pulley outside diameter, and is listed with six belts. If the belt profile, pulley section, or bracket spacing differs from the removed unit, stop and confirm before fitting.

When checking replacement suitability, compare the mounting hole diameter of 8 / M8x1.25 and the 10mm adjusting hole diameter with the vehicle’s existing alternator bracket and fasteners. Small differences in these dimensions can affect fitment even when the alternator looks similar.

For the listed Volkswagen and SEAT applications, use the vehicle details as a guide only and confirm by part number and application details before purchase. The same model range can have different charging components depending on build and equipment, so the safest check is still the removed unit’s identifiers and mounting dimensions.

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 MG252 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.
