Rebuilt Alternators

Coventry West is proud to feature and sell “Professional Preferred” Bosch remanufactured alternators and starters.

Bosch remanufactured alternators and starters carry the strongest warranty in the business: 24 months with unlimited mileage on units used on on-commercial passenger cars and light trucks! Bosch remanufactured starters and alternators also feature the Bosch Ultimate Protection Plan, which provides that, should your Bosch reman starter or alternator fail during the two years after purchase, you are eligible for a free jump start, or tow if necessary, from a qualified Road Service Provider. This service is available 24 hours a day, 365 days a year, anywhere in the U.S or Canada, after promptly registering your component purchase, by presenting the Bosch Ultimate Protection Plan Access Card at time of service. Robert Bosch LLC is one of the oldest and most respected automotive component manufacturers in the world, with a long history dating back to the earliest days of the horseless carriage, and it is very difficult to find a car in production today that doesn’t carry a Bosch-produced part somewhere on it!
