Common Auto Repair Terms Explained: A Driver’s Guide to Automotive Service Language
Auto repair conversations can sometimes feel overwhelming, especially when technicians use industry terms that most drivers don’t hear every day. Understanding common auto repair terminology helps you make informed decisions, communicate confidently with service professionals, and better understand what your vehicle needs.
At Art Morse Auto Group, we believe an informed driver is a confident driver. This glossary breaks down common automotive repair terms in plain English, so you know exactly what’s being discussed when your vehicle is in the shop.
Common Auto Repair Terms Explained
OEM (Original Equipment Manufacturer)
OEM parts are made by the same manufacturer that produced the original components in your vehicle. These parts are designed to meet factory specifications for fit, performance, and durability.
Aftermarket Parts
Aftermarket parts are produced by third-party manufacturers. While some can be high quality, others may vary in fit and longevity compared to OEM parts.
Diagnostics
Diagnostics refers to the process of using specialized tools and software to identify issues within a vehicle’s systems. Diagnostic testing helps technicians accurately pinpoint problems before making repairs.
Torque
Torque measures the rotational force applied to fasteners such as bolts and lug nuts. Proper torque ensures components are securely fastened without being over-tightened or damaged.
Check Engine Light
A dashboard warning light that indicates a potential issue with the engine, emissions system, or sensors. It may signal anything from a loose gas cap to a more serious mechanical concern.
Transmission
The transmission transfers power from the engine to the wheels. It controls vehicle speed and torque and can be either automatic or manual.
Coolant (Antifreeze)
Coolant is a fluid that regulates engine temperature by preventing overheating and freezing. Proper coolant levels are critical to engine performance.
Brake Pads
Brake pads are friction components that press against the brake rotors to slow or stop the vehicle. Worn brake pads reduce braking effectiveness and should be replaced promptly.
Rotors
Brake rotors are metal discs that work with brake pads to stop the vehicle. Warped or worn rotors can cause vibration or reduced braking performance.
Alignment
Wheel alignment adjusts the angles of the wheels to ensure proper contact with the road. Proper alignment improves tire life, handling, and fuel efficiency.
Suspension
The suspension system supports the vehicle’s weight and absorbs road impacts. It includes components such as shocks, struts, and springs.
Serpentine Belt
A single belt that powers multiple engine components, including the alternator, power steering pump, and air conditioning compressor.
Battery
The vehicle battery supplies electrical power to start the engine and run electronics. Most car batteries last three to five years.
Preventative Maintenance
Routine services, such as oil changes, tire rotations, and inspections, are performed to prevent future breakdowns and extend vehicle life.
