This Bosch alternator is a 12V, 70A passenger alternator identified by part number 1986A01292. It is listed as an OE product and is supplied as a single unit, so it suits buyers replacing a worn charging component with the same core electrical rating and application style.

A one year warranty is listed, and the alternator is manufactured in China. Packaging dimensions are 24 cm long, 18.5 cm wide, and 20 cm high, which may be useful when planning freight, storage, or workshop handling.

Recommended additional repairs include the V-belt or V-ribbed belt. When replacing an alternator, it is sensible to inspect the belt condition and related drive components at the same time, especially on a 70A charging system where belt drive condition affects performance and installation quality.

Application and Buying Notes

The most important checks for this alternator are the 12V system voltage, 70A output, part number 1986A01292, and the double pivot lever fastening type. Those details should be matched against the removed unit or the vehicle’s parts listing before you buy, because alternators can differ even within the same model range.

This Bosch unit is listed as an OE product, which makes it a sensible choice where the original specification matters. The alternator type is excl. vacuum pump, so buyers should not assume compatibility with a setup that relies on a vacuum pump arrangement. That distinction is worth confirming on the existing part.

The fitment information provided points to Toyota Corolla applications, including model years from 1992 through 2002 in the supplied sample data. Even so, the correct approach is to verify the actual vehicle build and the original alternator details, since model year alone is not enough to confirm fitment on its own.

If you are cross-checking stock for a workshop job, the useful identifiers here are Bosch, 1986A01292, 12V, and 70A. Those are the quickest reference points when comparing catalogue entries, supplier listings, or the old unit on the bench, especially when there are multiple alternator variants across Toyota applications.

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 1986A01292 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 voltage 12 and output 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA COROLLA, TOYOTA COROLLA 1992, TOYOTA COROLLA 1993, TOYOTA COROLLA 1994. 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.
