Auto Repair Glossary for Erie Homeowners

Adjusting the angles of your wheels to the manufacturer's specifications. Erie's potholes and rough winter roads frequently knock wheels out of alignment.

All-season tires handle moderate winter conditions; dedicated winter tires provide significantly better traction in snow and ice. Many Erie drivers switch to winter tires November through April.

Brake pads are the friction material that presses against the rotor (disc) to slow your car. Pads wear faster and need replacement every 30,000-70,000 miles; rotors last longer but may need resurfacing or replacement.

An emissions control device that converts harmful exhaust gases into less harmful ones. Pennsylvania requires a functioning catalytic converter to pass the annual safety inspection.

Draining old antifreeze/coolant and replacing it with fresh fluid. Critical in Erie — proper coolant protects your engine from freezing in winter and overheating in summer.

Constant velocity joints allow your drive axles to flex while transmitting power. The rubber boots that protect them crack over time; a torn boot leads to joint failure if not caught early.

Using an OBD-II scanner to read your vehicle's computer codes and identify problems. Modern vehicles have dozens of sensors, and a diagnostic scan pinpoints issues quickly.

On-Board Diagnostics, the standardized vehicle computer system present in all cars since 1996. Mechanics connect to the OBD-II port to read trouble codes and diagnose issues.

An annual vehicle safety inspection required by PA law. Covers brakes, tires, lights, steering, suspension, and exhaust. Erie County also requires an emissions inspection.

The system of springs, shocks, struts, and linkages connecting your vehicle to its wheels. Erie's road conditions accelerate suspension wear.

A single belt that drives multiple engine accessories (alternator, power steering, AC compressor). Belts degrade faster in Erie's temperature extremes and should be inspected regularly.

A complete replacement of your transmission fluid, removing old fluid and contaminants. Recommended every 30,000-60,000 miles depending on driving conditions.

A belt or chain that synchronizes the engine's camshaft and crankshaft. A broken timing belt can cause catastrophic engine damage. Replacement intervals vary by manufacturer.

A protective coating applied to the vehicle's undercarriage to prevent rust. Highly recommended in Erie due to heavy road salt use during winter months.

Bearings that allow your wheels to spin freely on the axle. A humming or grinding noise that changes with speed often indicates a worn wheel bearing.
