Serving La Mesa since 1972, Peanuts Auto Repair on Lake Murray Boulevard near Lake Murray holds ASE-certified technicians and backs every job with a two-year, 24,000-mile warranty. The shop specializes in Japanese, American, and select European vehicles, handling radiator rebuilds, hybrid battery diagnostics, and clutch replacements that body-and-paint facilities like Fix Auto La Mesa typically refer back for mechanical follow-up. Engine diagnostics run through OBD-II and manufacturer-specific scan tools to isolate misfire codes, evaporative-emission leaks, and transmission solenoid faults before any teardown begins. Brake services include ABS module testing, rotor resurfacing, and caliper rebuilds, while suspension work extends to strut assembly replacement and alignment prep — with tire mounting and balancing completed at specialists like Evans Tire down Lake Murray Boulevard. Highest-complexity repairs involve full radiator-core replacement on aluminum-and-plastic composite units, requiring pressure testing to 18 PSI and coolant-system vacuum fill to eliminate air pockets before road testing.
