15 Car Parts and What They Do In Your Car

August 10, 2023 by Denver Express Car Care

According to the Global Language Monitor, the English language currently contains over 1 million words. Of course, we don’t use nearly that many in our everyday language. 

The Oxford English Dictionary contains 171,476 words in current use, while Webster’s Third New International Dictionary includes 470,000 entries of both current use and obsolete words. 

Even with this many words available to us, the average individual has a vocabulary size of about 48,000 words. Yet most of us never use more than the first 1,000 or so on a regular basis. 

So when words like transmission, radiator, or gearbox pop up, it’s only natural to scratch your head and think about what they mean. We know car parts are essential. We understand car parts work together to create one of our most meaningful personal assets. But what are they, and how do they work? 

We’ve compiled a list of 15 essential car parts, how they work, and what could go wrong. It’s a great place to start to get to know your car a little better. 

Air Filter: Breathing Easy

Picture this: you’re running a marathon, and suddenly, your nose gets clogged, making it hard to breathe. That’s essentially how a car’s air filter works. It ensures that clean air reaches the engine by trapping dust, dirt, and debris, preventing them from entering and potentially causing damage. 

Replace your air filter regularly for better engine performance and fuel efficiency.

Alternator: Power Provider

The alternator is like a mini power station in your car. It charges the battery while the engine is running and supplies electrical power to various components, such as lights, radio, and power windows. Without a functioning alternator, you’d find yourself stuck in the dark with a dead battery.

15 Car Parts and What They Do In Your Car

If you suspect you have a problem with the alternator, have it checked by one of our mechanics. 

Battery: Life-Giver

Your car’s battery is the heartbeat of the electrical system. It stores energy to start the engine and powers all the electrical components when the alternator can’t supply enough electricity. 

Regularly check your battery’s health and make sure the connections are clean and secure to avoid unexpected breakdowns.

Brake Rotors: Slowing Down Safely

Imagine driving without brakes – terrifying, right? Brake rotors, also known as brake discs, are crucial for stopping your car safely. When you apply the brakes, the brake pads clamp onto the rotors, creating friction that slows down your car. 

Like other car parts, brake rotors have a useful life. Check your owner’s manual for guidelines, then keep an eye on these vital components and replace them when they become too thin or damaged.

Catalytic Converter: Environment’s Ally

In the age of environmental consciousness, the catalytic converter plays a vital role in reducing harmful emissions. It converts harmful gasses, like carbon monoxide and nitrogen oxides, into less toxic substances before they exit through the exhaust pipe. 

Always ensure your catalytic converter is functioning correctly to minimize your car’s environmental impact.

Clutch: Seamless Gear Changes

Manual transmission lovers, this one’s for you! The clutch allows you to shift gears smoothly by temporarily disconnecting the engine from the transmission. It’s essential to avoid riding the clutch or engaging in abrupt gear changes to prevent premature wear and tear.

This is where paying attention to how your car operates matters. If you notice changes in the way the clutch operates, bring it in for a thorough inspection. 

Emissions Control System: Caring for the Environment

In an era where environmental concerns are at the forefront of our minds, the emissions control system in your car plays a critical role in reducing harmful pollutants released into the atmosphere. As cars run on internal combustion engines, they produce various harmful gasses as byproducts of the combustion process: Nitrogen Oxides (NOx), Hydrocarbons (HC), and Carbon Monoxide (CO). The emissions control system employs various components to minimize the release of these harmful gasses into the atmosphere.

To keep the emissions control system functioning optimally, it’s crucial to follow the manufacturer’s recommended maintenance schedule. Regular servicing and replacing worn-out components are essential to ensure that your car remains compliant with emission standards and contributes to a cleaner environment.

Gearbox: Power Transfer Pro

The gearbox, or transmission, is the bridge between your car’s engine and wheels. It allows you to change gears, enabling the engine to operate efficiently at various speeds. 

Regular transmission maintenance can extend its lifespan and keep your shifts buttery smooth.

Ignition: Start It Up!

The ignition system gets your car’s engine roaring to life. It creates and delivers the high-voltage sparks needed to ignite the air-fuel mixture in the engine’s cylinders. Modern vehicles mostly have electronic ignition systems, which are more reliable and efficient than the older mechanical ones. Yet things can still go wrong. 

Having trouble starting your car? Don’t automatically assume it’s the battery. The ignition can and does wear down over time. 

Radiator: Keeping Cool Under Pressure

Driving generates a lot of heat under the hood, but fear not – the radiator is here to keep things cool. It circulates coolant through the engine, absorbing excess heat, and then releases that heat into the air. 

A well-maintained radiator is vital to prevent overheating, which can cause severe engine damage. That starts with checking the coolant occasionally and ensuring there aren’t any leaks or problems with the system. 

Shock Absorbers: Smooth Ride Ahead

Ever wonder why you don’t feel every bump and pothole on the road? Thank your car’s shock absorbers for that! They dampen the impact of uneven surfaces, providing you with a smoother and more comfortable ride. 

Replace worn-out shocks to maintain optimal handling and comfort.

Spark Plug: Igniting the Magic

Spark plugs might be small, but they play a big role in your car’s performance. They generate sparks that ignite the air-fuel mixture in the engine’s cylinders, creating the controlled explosions that move your car. 

Proper maintenance and periodic replacements will keep your engine running like a champ.

Thermostat: Temperature Regulator

The thermostat is the ultimate temperature regulator. It monitors the engine’s temperature and opens or closes to control the flow of coolant. This ensures that your engine stays within its optimal temperature range, leading to better fuel efficiency and performance.

A malfunctioning thermostat can cause the engine to not operate at an optimal temperature, which can cause it to overheat. Keep an eye on your dashboard and pay attention to all notifications. 

Transmission: Shifting Gears Seamlessly

The transmission allows your car to change gears and transfer power from the engine to the wheels. It comes in various types, including manual, automatic, and continuously variable transmissions (CVT). Each type has its benefits and quirks, but they all serve the same purpose – providing a smooth and efficient ride.

Regular maintenance and inspections will prevent deterioration in any part of the transmission system, keeping your car on the road longer. 

Water Pump: Coolant Circulator

The water pump keeps the coolant flowing through the engine and radiator, regulating the engine’s temperature. Without it, the engine would overheat quickly, leading to potential damage. 

Regular maintenance will ensure your water pump remains in good shape.

These are just a few of the many parts you’ll find on your car …

And there you have it – 15 car parts and their essential functions! 

Cars are complex machines with numerous components working harmoniously to get you from point A to point B. Understanding these parts can help you appreciate the engineering marvel that is your car and empower you to take better care of it. 

Remember, regular maintenance and timely repairs are the keys to keeping your car running smoothly for years. 

Happy driving!

The Most Damaged Suspension System Car Parts When You Hit Potholes

September 14, 2019 by Denver Express Car Care

You’ve probably heard the joke that in Colorado, there are four seasons: fall, winter, spring, and construction. Yes, summer is a great time to get out of the house and enjoy lots of sunny days and warm weather. But driving around town can leave you a little agitated at best.

It’s hard to miss the number of potholes that lurk all over town. They may start out small, but they quickly grow into a car-eating disaster.The Most Damaged Suspension System Car Parts When You Hit Potholes

Potholes are caused by the expansion and contraction of water. As cracks occur in the pavement, water leaks down underneath. On cold days it freezes. Think of it like an ice cube; it moves from a puddle of water to a solid, frozen shape. That pushes and shoves the pavement in new directions.

Then on warm days, it thaws. The water moves to new locations, penetrating even more of the uneven pavement. It flows into new cracks, and takes up more space.

Over and over this occurs, all winter long.

Of course, that’s not the only thing that helps a pothole grow. Especially on a busy road, cars and trucks drive over it, pounding the pavement in all sorts of directions. The weight makes the material weaker, breaks it off, and causes it to move in new ways. The more this occurs, the larger the pothole grows.

Colorado has thousands of miles of paved roads weaving in and out of some of the most beautiful country in the world. If you haven’t had the chance to drive across this state, try picking one from this list and enjoy the breathtaking views.

As you round each corner and move up and down the hills, try and avoid the potholes at all costs. Brace yourself when you simply can’t. And understand the impact each pothole has on your car parts, the damage it creates on your vehicle’s suspension system. By being aware, you can learn when it’s time to bring your car into our shop and get the suspension fixed before further damage can occur.

What a pothole can do to your car

When your car hits a pothole, it’s usually the pothole that will win. It can damage your tires and wheels, cause alignment issues, or even cause premature wear to your shocks. When you hit a pothole, it can damage:

  • Your wheels – it can bend or even crack wheel rims
  • Your tires – flat tires, uneven wear, and weakened belts and cords
  • Your alignment – ever noticed your car pulling to one side or the other?
  • Your suspension system – it can impact shocks, struts, springs, and more
  • Your exhaust system – cracks, leaks, and holes can put you at risk

That damage adds up to quite a lot – according to AAA auto club, over $3 billion a year.

How do you know if your car has been damaged by a pothole?

Here in Colorado, it’s hard to avoid potholes. But pay attention to the ones that make you cringe and groan. You know when you hit an especially bad one. It rattles the entire car. And once this happens, be on the lookout for these things:

  • Do you have to turn your steering wheel so it’s crooked to stay straight on the road? It’s a sign the steering component is bent.
  • Do you notice excessive bouncing and loss of control as you drive? It’s a sign of steering and suspension issues.
  • Have you noticed pulling to one side or uneven tire wear? It’s a sign of problems with your alignment.
  • Are there bulges on tire sidewalls or dents in the wheel? It’s symptoms of tire damage.
  • Do you notice a vibration in your steering wheel? It’s a sign of a bent rim.
  • Do you find fluids underneath your car when you pull away? It could be a signal of a line or hose that’s cracked, wiggled loose, or no longer functioning.
  • Is your exhaust system noisier than normal? It could be a result of damage from the undercarriage of your car scraping because of the pothole.

What if you think you’ve sustained damage after hitting a pothole?

Or course, it depends on what the damage is. Some damage is more dire than others. If you don’t come in with some issues, it can put you at risk for more serious damage, or for an accident.

You should never take your car for granted. You should always take the approach of “listen, sense, and look.”

Every time you start your car, listen for sounds that weren’t there before. Do you hear a new rattle? Do you hear a new clank? Each of these sounds is trying to tell you that something is wrong with your car. Do a little sleuthing and find out exactly where it’s coming from. Even if you can’t determine the exact cause, it will help you be able to talk more clearly with your mechanic when you bring your vehicle in.

Gain a good sense for what your car feels like every time you take it out on the road. Learn how the steering feels as you make turns and keep your car on the road. Do you notice different movements, especially at varying speeds? Do things change on the highway? Do things change when you come to a stop? Note these differences and describe them when you come into the shop.

You should also make a periodic overview of your car, both inside and out. Just like a pilot makes a full check before he pulls the plane out and flies it to the next destination, so too should you do a thorough investigation once in awhile, to ensure everything looks okay. Glance under the car, do you see part of the exhaust system hanging free? Do the tires look deflated or flat? When you pop the hood, does something appear to be out of place?

You don’t need a certificate in auto mechanics to notice when something is wrong with your car. And considering how important your suspension system is to the way your car behaves on the road, it’s one of the most important systems to watch.

How many potholes have you hit this year? Isn’t it time to make sure your suspension system is fully working, and won’t cause you problems down the road?
