Installation Notes and Tips

Verify starter number and brush width before installation. Match the application to the vehicle year, make, model, and any notes shown in the fitment data, especially on 1980-1984 GM and Ford listings with starter-number or production notes. Clean the starter housing and inspect the commutator, bushings, and related electrical contacts during service.
