Product Details

MPA Electrical New alternators are built to replace the original charging unit with the correct fit, mounting layout, and electrical function. The 13241N uses a rear-view plug clock position of 4 o’clock with the main mounting ear at 6 o’clock, which helps match the factory installation on the listed Toyota applications. If you are sourcing a Toyota 4Runner alternator or a Toyota Pickup alternator for the 1988-1992 model years, this unit provides the specified OE-style configuration in a new replacement assembly. Part number 13241N also helps confirm the correct match during lookup and cross-reference checks.
