Full-Service Auto Repair in San Antonio
Overnight Collision Center is also a full mechanical repair shop. From routine oil changes to engine and transmission work, our ASE-trained technicians keep San Antonio drivers on the road — using the same shop, same standards, and same warranty-backed quality that earned us our reputation for collision work.
Everything Your Vehicle Needs
Whether it's a quick oil change or a major engine repair, we service all makes and models with the same care we put into every collision job.
Oil Changes & Fluids
Full-synthetic, synthetic blend, and conventional oil changes. We also handle transmission fluid, coolant flushes, brake fluid, power steering and differential service.
Brakes & Rotors
Pad and rotor replacement, brake fluid flushes, caliper service, and parking-brake adjustment. Quiet, smooth stopping power with quality parts.
Diagnostics & Check-Engine
Factory-grade scan tools to pinpoint check-engine lights, drivability issues, and intermittent faults — no guesswork, no parts-cannon.
A/C & Heating
A/C performance checks, leak detection, recharge service, compressor and condenser replacement. Stay cool through every San Antonio summer.
Batteries, Alternators & Starters
Charging-system tests, battery replacement, alternator and starter service. We get you reliably starting every morning.
Suspension & Steering
Struts, shocks, control arms, tie rods, ball joints, wheel bearings and alignments. Restore ride quality and tire wear.
Tune-Ups & Maintenance
Spark plugs, ignition coils, filters, belts, hoses and scheduled factory maintenance to keep your warranty intact and your vehicle running long.
Transmission & Engine Repair
From minor leaks and seal replacement to timing components, head gaskets and full engine or transmission service — we handle major mechanical work in-house.
Collision & Mechanical Under One Roof
After a collision, many vehicles need more than panel and paint work — suspension components, sensors, A/C lines, and drivetrain parts may need attention too. Because we handle both collision and mechanical repair in-house, you avoid bouncing between shops and get your vehicle back faster.
