Auto Repair & Tire Glossary

This auto repair & tire glossary helps drivers understand common auto repair and tire service terms used at Bethford Auto & Tire in Blasdell. Whether you’re scheduling brake repair, buying new tires, or trying to decode a dashboard warning, this guide explains essential automotive terms in plain language.

A

ABS (Anti-Lock Braking System): Prevents wheel lock-up during hard braking to maintain traction and control. Inspections are often part of brake service.

Alignment: Adjusts suspension angles so tires meet the road evenly. A proper wheel alignment improves handling, tire wear, and fuel efficiency.

Alternator: Charges the battery and powers the electrical system while the engine runs. A weak alternator can cause dim lights or stalling.

B

Balance: Ensures even weight distribution around a tire and wheel assembly. Tire balancing prevents vibration and uneven tread wear during tire service.

Battery: Supplies power to start your vehicle and operate electronics. Weak or corroded batteries often show during seasonal checkups or diagnostic testing.

Brake Fluid: Transfers pressure from the brake pedal to pads or shoes. Low levels or leaks reduce braking power and are checked during brake repair.

Brake Pads: Friction material that clamps against rotors to stop your car. Replace pads regularly during brake service to maintain safety.

C

Cabin Air Filter: Filters dust, pollen, and debris entering your cabin. Replaced during routine maintenance for clean airflow.

Catalytic Converter: Reduces harmful emissions by converting gases into less toxic compounds. Issues trigger the check engine light.

Check Engine Light: Alerts drivers to issues in the engine or emissions system. A diagnostic scan identifies the problem.

Coolant (Antifreeze): Regulates engine temperature to prevent overheating or freezing. Levels are checked during engine service.

D

Diagnostic Scan: Reads computer codes to find engine or sensor issues. Available during auto repair diagnostics.

Differential: Distributes power to wheels while turning. Noise or vibration may require steering or suspension repair.

Disc Brake: Uses calipers, rotors, and pads to stop the car. The most common brake system serviced during brake repair.

E

Engine Oil: Lubricates moving engine parts and prevents wear. Change oil every 3,000–5,000 miles during a routine oil change.

Exhaust System: Channels gases away from the engine, reduces noise, and filters emissions. Includes muffler and catalytic converter components.

F

Fuel Filter: Removes impurities before fuel reaches the engine. A clogged filter causes poor performance and should be replaced during maintenance.

Fuel Injector: Delivers fuel to each cylinder for combustion. Dirty injectors can cause rough idling or loss of power.

H

Head Gasket: Seals the engine block and cylinder head. A blown gasket causes overheating or coolant loss and needs professional engine repair.

I

Inspection: The annual New York State inspection ensures your car meets safety and emissions standards. Includes brakes, tires, lights, and more.

Idler Arm: Supports steering linkage and helps control alignment angles. Inspected during steering repair.

L

Lug Nut: Secures each wheel to the hub. Always torqued correctly after tire installation or state inspection.

M

Muffler: Part of the exhaust system that reduces engine noise. Damage can cause loud rumbling or vibration.

O

Oil Change: Routine replacement of used oil and filters to protect your engine. Schedule a full oil service regularly.

Oxygen Sensor: Monitors exhaust gases to optimize fuel efficiency and emissions. Replaced during engine diagnostics.

P

Power Steering Fluid: Enables smooth steering. Low fluid can cause stiff handling and is checked during steering service.

TPMS (Tire Pressure Monitoring System): Warns of low tire pressure. Alerts are addressed during tire service or alignment checks.

R

Rotor: Metal disc that brake pads clamp to stop your car. Resurfaced or replaced during brake service.

Tire Rotation: Moves tires to different positions for even wear. Recommended every 5,000–7,000 miles during tire service.

S

Serpentine Belt: Powers vital components like the alternator, power steering, and A/C compressor. Cracks or wear require belt replacement.

Shock Absorber: Controls suspension movement and ensures a smooth ride. Replaced during suspension repair.

Spark Plug: Ignites the air-fuel mixture in the engine. Replaced during tune-ups for peak performance.

Strut: A key part of your suspension system combining a shock absorber and spring. Serviced during suspension repair.

T

Tire Pressure: Air inside each tire measured in PSI. Proper inflation is checked during tire installation or alignment.

Tread Depth: Tire rubber thickness that provides traction. Replace tires at 2/32” depth for safety during tire service.

Timing Belt: Coordinates engine valves and pistons. Replace at intervals during major maintenance.

W

Wheel Bearing: Allows smooth wheel rotation. Noise or vibration can indicate wear needing suspension repair.

Wheel Alignment: The process of correcting tire angles for even wear and safe handling. Schedule your next alignment service online.
