Horsman Automotive on Santee's Railroad Avenue has operated continuously since 1966, when it opened as a two-bay Chevron gasoline station before expanding into the ten-bay full-service facility it occupies today. ASE-certified technicians handle light and medium duty drivetrain work from engine overhauls to differential service, with major transmission rebuilds routed to dedicated specialists including Advanced Automatic Transmissions on Ablette Road. The facility carries AAA Approved Auto Repair, NAPA Auto Care, and BBB A+ designations, and stocks ACDelco OEM-grade batteries, filters, and ignition components for domestic and import platforms. Suspension, alignment, and brake service round out the chassis program, with OEM-spec tire mounting and balancing coordinated through Alvarez Tire on Woodside Avenue for specialty fitments. Fleet maintenance capabilities cover multi-vehicle service scheduling across brakes, cooling systems, fuel injection cleaning, and steering components for light and medium duty commercial vehicles.
