ASE Master Certified technicians staff D & R Automotive in Santee, a NAPA Auto Care center on Prospect Avenue that has operated continuously since its 1982 founding. The shop handles everything from timing-chain replacements on Ford 3.5L EcoBoost engines to full brake overhauls, with tire and wheel service coordinated through Budget Tire Co of Santee a quarter-mile north on Prospect. AAA Approved Auto Repair status subjects the facility to regular third-party inspections, and the service scope spans AC, electrical, clutch, driveline, manual and automatic transmissions, and cooling systems. The diagnostic bay runs OBD-II and manufacturer-specific scan-tool protocols for imports including Acura, BMW, Mercedes-Benz, and Volkswagen alongside domestic Chevrolet, Ford, and RAM platforms. Post-collision mechanical work covering frame-related suspension geometry, headlight aim, and bumper-mounted sensor recalibration feeds into the structural repair pipeline that Fix Auto Santee completes farther south on the same Prospect Avenue corridor. Highest-complexity services include camshaft phaser and variable-valve-timing actuator replacements on direct-injection engines requiring factory-spec torque sequences and relearn procedures.
