  • Air Filter – The air filter is responsible for keeping the air in your engine clean. It is typically located in the air intake duct work leading to the engine.
  • Alternator – The alternator is what charges the battery in your car. It uses a pulley system to spin a generator which produces electricity.
  • Anti-lock Brakes (ABS) – ABS is a safety feature in modern cars that prevents the brakes from locking up under heavy braking. This allows the driver to maintain control of the vehicle during an emergency stop.
  • Brake Pads – Brake pads are what make contact with the brake rotors to create friction and slow down or stop the wheels from turning. They are made out of a high friction material like ceramic or semi-metallic and they will wear down over time with use.
  • Brake Rotors – Brake rotors are metal discs that the brake pads clamp down on to create friction and slow or stop the wheels from turning. They can warp or crack over time from heat and heavy use.
    Carburetor – The carburetor is responsible for mixing air and fuel to the correct ratio for combustion in your engine. It typically operates using a mechanical system that regulates the air and fuel flow.
  • Catalytic Converter – A catalytic converter is a device that reduces emissions from your car by converting harmful pollutants into less harmful gases before they are released into the atmosphere.
  • Clutch – The clutch is responsible for connecting and disconnecting the engine from the transmission so that you can shift gears. It typically uses a friction plate system to engage or disengage power to the wheels.



A-Z of Automotive Terminology

We all know that A-Z auto repair can be a confusing and daunting task, especially when you don’t know the lingo. To help you out, we’ve put together this A-Z guide of common automotive terms.


  • ABS: Anti-lock Braking System – This system prevents your brakes from locking up, giving you more control over your vehicle.
  • Air Filtration: The function of the air filter is to prevent dirt and debris from entering the engine.
  • Alternator: A battery is charged by the alternator while the engine is running, which powers the electrical system.
  • Ball Joint: Ball joints connect the control arms to the steering knuckles and allow for suspension movement.
  • Battery: The battery supplies power to both the starter motor and ignition system. It also stores power for accessories like lights and radio.
  • Brake Fluid: This fluid allows the brakes to work by transferring pressure from the pedal to the brake pads.
  • Caliper: The caliper houses the brake pads and uses hydraulic pressure to squeeze them against the rotor, slowing or stopping your vehicle.
  • Clutch: The clutch connects or disconnects the engine from the transmission, allowing you to shift gears.
  • CV Joint: CV (constant velocity) joints allow power to be transferred from the transaxle to the wheels at a constant speed, even as they move up and down with suspension travel.
  • Diesel Engine: A diesel engine is similar to a gasoline engine, but uses fuel that is ignited by compression instead of spark plugs.
  • ECU: Electronic Control Unit – The ECU controls the engine’s various functions including fuel and ignition timing.
  • Fluid Levels: Fluids such as oil, coolant, and brake fluid must be checked regularly for proper levels.
  • Gasket: A gasket seals two parts together, preventing leaks in the engine or other components.
  • Harmonic Balancer: The harmonic balancer absorbs vibrations from the engine to reduce wear on other components.
  • Ignition Coil: The ignition coil creates an electrical spark that ignites the fuel-air mixture in the cylinder.
  • Jounce Bumper: Jounce bumpers are rubber shocks that limit suspension travel and protect against bottoming out.
  • K&N Filter: K&N filters use a washable cotton filter material to provide superior air filtration with less restriction than traditional paper filters.
  • Lug Nuts: Lug nuts secure the wheel to the hub assembly and should be tightened to manufacturer specifications.
  • Muffler: The muffler reduces exhaust noise and directs hot gases away from the engine compartment.
  • Oil Change: Oil changes should be done regularly to keep the engine running smoothly and prevent damage.
  • Piston: Pistons move up and down in the cylinders, compressing fuel-air mixture and creating power.
  • Radiator: The radiator cools the engine by transferring heat from the coolant to the outside air.
  • Spark Plugs: Spark plugs create an electrical spark that ignites the fuel-air mixture in each cylinder of the engine.
  • Timing Belt: The timing belt synchronizes the opening and closing of valves with the rotation of the crankshaft.
  • U-Joint: U-joints connect two shafts together at an angle and allow for movement.
  • Vacuum Hose: Vacuum hoses carry engine vacuum to various components such as brakes, transmission, and climate control systems.
  • Water Pump: The water pump circulates coolant through the engine to keep it running at optimal temperature.
  • Xenon Headlights: Xenon headlights provide brighter illumination than traditional halogen bulbs while using less energy.
  • Yoke: A yoke is a U-shaped component used to connect two parts with a pivot or swivel point, such as on a driveshaft.
  • Zinc Additive: Zinc additive is added to some motor oils to provide extra protection against wear.



Commonly Used Repair Terms

The world of A-Z auto repair can be a confusing one, especially if you’re not familiar with all the jargon. To help you make sense of it all, we’ve put together a list of commonly used repair terms, from A to Z.

  • A: Alignment. This refers to the adjustment of your car’s suspension so that the wheels are aligned properly. This is important for proper handling and avoiding premature tire wear.
  • B: Balance. When your car’s wheels are balanced, it means that they’re evenly weighted. This helps to ensure a smooth ride and avoid vibration.
  • C: Caliper. The caliper is the part of your car’s braking system that squeezes the brake pads against the rotors (or drums).
  • D: Disc Brakes. These are the most common type of brakes found on modern cars. They work by using calipers to squeeze brake pads against rotors (discs) in order to create friction and slow down the vehicle.
  • E: Engine. The engine is the heart of your car, providing power to turn the wheels and move the vehicle forward. It commonly operates using either gasoline or diesel fuel.
  • F:Filter. There are many different types of filters in a car, but they all serve the same purpose – to remove impurities from liquids or gases before they enter into vital components of the vehicle. For example, fuel filters remove dirt and debris from gasoline before it reaches the engine.
  • G : Gasket. A gasket is a component that is used to seal two parts together. They are typically made of rubber, metal, or paper and can be found in many places throughout the vehicle.
  • H: Hubcap. A hubcap is a decorative cover that fits over the center of the wheel. They come in all shapes, sizes, and colors and can be removed for cleaning or access to the lug nuts.
  • I: Ignition System. The ignition system consists of several components that work together to create and ignite the fuel/air mixture inside an engine’s cylinders. It includes spark plugs, coils, distributors, and more.
  • J: Jack Stand. A jack stand is a safety device used when lifting up a car with a jack in order to support it until repairs are complete or tires are changed.
  • K: Knock Sensor. A knock sensor detects vibrations within an engine caused by pre-ignition (knocking) and adjusts the ignition timing accordingly to prevent further damage from occurring.
  • L: Lug Nut/Bolt. These fasteners attach wheels to cars so they don’t fall off while driving! Make sure they’re tightened properly before hitting the road!
  • M: Muff ler. The muffler is part of the exhaust system and helps to reduce engine noise, as well as decrease harmful emissions from entering the environment.
  • N: Neutral Safety Switch. This switch prevents an engine from starting unless it is in neutral or park. This is usually found on automatic transmission vehicles and is a safety feature to prevent the car from moving while starting it.
  • O: Oxygen Sensor. The oxygen sensor measures the amount of oxygen in the vehicle’s exhaust system and informs the engine control unit (ECU) so that it can adjust fuel/air mixture accordingly for better performance.
  • P: Power Steering Pump. Found in most cars equipped with power steering, this pump pressurizes fluid which is then used to assist with steering effort when turning the wheels.
  • Q: Quality Control. Quality control is a crucial part of any A-Z auto repair shop and involves testing parts, components, and systems for defects before installing them into a customer’s vehicle.
  • R: Radiator Flush. A radiator flush involves draining old coolant from a car’s radiator system and replacing it with fresh coolant to help ensure proper cooling of an engine and prevent overheating issues.
  • S: Spark Plug Wires/ Cables. These are wires connecting the spark plugs to the distributor which carries high voltage current from the ignition system to create a spark in the combustion chamber and ignite the fuel/air mixture.
  • T: Timing Belt. The timing belt is a rubber belt located in the engine that connects to various components (such as the camshaft and crankshaft) in order to synchronize their movements.
  • U: U-Joints. U-joints (or universal joints) are parts located in the drivetrain which allow for power transfer from one part of an axle to another, even when there is angular misalignment between them.
  • V: Vacuum Leak. A vacuum leak occurs when air enters a sealed system, such as an intake manifold or brake booster, due to a crack or hole in one of its components. This can cause poor engine performance or loss of braking power.
  • W: Wheel Bearing/Hub Assembly. The wheel bearing is responsible for allowing your car’s wheels to rotate freely while supporting their weight at the same time. It consists of several parts including an inner and outer bearing, seals, and hub assembly.
  • X: X-Brace/Strut Tower Brace. An X-Brace is a metal support bar (usually made of aluminum or steel) that goes across the top of the engine bay to help stiffen and strengthen the chassis. It helps reduce body flex during hard cornering and prevents suspension components from rubbing against each other due to excessive movement.
  • Y: Yoke. A yoke is a piece of hardware that connects the drivetrain components together, such as the transmission, differential, and axles in order to transfer power from one part to another.
  • Z: Zero Point Calibration. This is a procedure done on cars with electronic suspension systems in order to ensure that all sensors are calibrated correctly so that the system functions properly.



Diagnosing Problems with Your Vehicle

If you’re having trouble with your vehicle, it’s important to be able to diagnose the problem so that you can get it fixed. Here are some common issues that you might experience, and how to diagnose them:

  • Engine problems: If your engine is making strange noises or doesn’t seem to be running smoothly, there could be a problem. Try checking the oil level and quality, as well as the spark plugs, to see if they need to be replaced.
  • Brake problems: If your brakes are squealing or feel less responsive than usual, there could be an issue with the pads or shoes. Verify whether they require replacement.
  • Suspension problems: If your car feels like it’s bouncing more than usual, or the ride is rougher than normal, there may be an issue with the shocks or springs. Have a mechanic take a look to see if they need to be replaced.



How to Choose a Mechanic: A-Z Auto Repair

When your car needs repair, it can be difficult to know where to take it. With so many options out there, how do you choose the right mechanic? When making your decision, keep the following in mind:

1. Make sure the mechanic is certified. The National Institute for Automotive Service Excellence (ASE) is one of several organizations that certify mechanics. A certified mechanic has passed a test demonstrating their knowledge and skills in A-Z auto repair.

2. Ask for recommendations. Talk to friends, family, and co-workers to see if they have any recommendations for a good mechanic. After obtaining a few names, you can explore each one to determine if they align well with your preferences.

3. Consider the location. You may want to choose a mechanic that is close to your home or work, so you don’t have to travel far for repairs.

4. Compare prices. Get estimates from several different mechanics before making your final decision.Be sure to ask about any specials or discounts that may be available.

5. Read reviews. Check online review sites or ask the mechanic for references from past customers. This will give you an idea of what others think of their workmanship and customer service skills .



Cost and Time Considerations for Repairs

Before you take your car in for repairs, it’s important to consider the cost and time commitment involved. Depending on the severity of the issue, repairs can be expensive and time-consuming.

If you’re facing a major repair, such as a transmission replacement, you can expect to pay several thousand dollars. Less extensive repairs, like replacing a catalytic converter, can still set you back a couple hundred dollars.

In addition to the financial cost of repairs, there is also the matter of time. Many repairs will require your car to be in the shop for a day or more. This can be inconvenient if you rely on your car for transportation.

Of course, the best way to avoid costly and time-consuming repairs is to practice preventive maintenance. Keeping up with regular oil changes and tune-ups can help you avoid major issues down the road.



Tips to Avoid Unnecessary Repairs

A-Z Auto repairs can be expensive, as we all know. But, there are ways to avoid unnecessary repairs and save yourself some money. Here are a few tips:

  • Read your owner’s manual. It’s important to be familiar with your vehicle and know when it’s time for routine maintenance. This will help you avoid major repairs down the road.
  • Be proactive about maintenance. Address issues before they become broken. Regularly check your fluids, tires, and brakes to make sure everything is in working order.
  • Pay attention to warning signs. If something doesn’t feel right while you’re driving, pay attention to it and get it checked out as soon as possible. Ignoring a problem will only make it worse and more expensive to fix later on.
  • Shop around for quotes. When you do need repairs, get multiple quotes from different shops before making a decision. This will help ensure you’re getting the best price for the work that needs to be done.
