Your sedan’s exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your sedan. Maintaining it is good Conder’s Automotive auto advice for Mount Juliet motorists, but it’s also good health advice and good environmental advice.
The exhaust system includes your emissions system. Because this system may affect your health and the health of our Nashville area environment, it is subject to strict government regulations. Satisfying these regulations demands some high-tech, computer-controlled equipment, which means that the emissions system is a lot more sophisticated than it was thirty years ago. Most auto manufacturers recommend that you have your sedan exhaust and emissions systems checked by a qualified service professional at regular intervals.
The exhaust system starts with the exhaust manifold. The manifold is attached to the sedan engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is essential that Nashville motorists keep their exhaust system in good repair.
The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air. So it is important that exhaust pipes get a diagnostic examination regularly.
The catalytic converter is the next vital component of your sedan exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn’t require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in Tennessee. Call Conder’s Automotive at 615-758-1515 if you suspect a problem with your catalytic converter.
Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the sedan engine’s computer keep the fuel-to-air mixture at optimal levels.
The muffler is also part of your sedan exhaust system, but it deals with a different kind of emission. It keeps your sedan from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.
It is critical for damaged mufflers be replaced immediately at your Mount Juliet automotive service center, especially if they are leaking. Not only will the extra noise annoy your Mount Juliet neighbors, a leaky muffler could be serious.
The entire exhaust system is attached to your sedan by hangers and clamps. These fasteners can rust, come loose or break. The essential components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and expensive damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.
Let’s not forget the tailpipe. It’s the last essential piece in the exhaust system — and of your sedan, for that matter. Exhaust fumes exit your sedan through the tailpipe.
If your sedan has any of the following symptoms, it may have a problem with the exhaust system: it’s hard to start, it runs rough, it’s noisy, it’s smoking. Also, if your “check engine” light comes on, especially if it’s flashing, it is important to get your sedan to Conder’s Automotive in Mount Juliet right away. Often, the “check engine” light indicates a problem with the emissions system.
Caring for your sedan exhaust system yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.
The exhaust system on a vehicle is more complex than most Mount Juliet auto owners realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All Tennessee folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That’s why preventive maintenance on your exhaust system is so essential. We can help you with that at Conder’s Automotive in Mount Juliet.
The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.
One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it, and you will die.
To keep this gas, and others, from entering your sedan passenger compartment, the connections from the manifold to the engine and from the manifold to the exhaust pipes are sealed with gaskets. These connections should be routinely inspected at Conder’s Automotive for cracks and to check if they have come loose.
The exhaust pipes can also get damaged, allowing dangerous gases to leak into your passenger compartment. These pipes can rust or be dented or broken by rocks and other Nashville roadway debris, so they need to be inspected regularly.
The catalytic converter is the next component in your sedan exhaust system. You can breathe a sigh of relief now, because this is where the dangerous engine gases are converted into carbon dioxide and water, greatly reducing the amount of harmful emissions in your exhaust. You’ll also be happy to know that your catalytic converter doesn’t require maintenance. However, it will wear out. If you fail an emissions inspection because of a faulty catalytic converter, you need to replace it.
The muffler’s job is far less critical, but far more noticeable, than the catalytic converter’s. It dampens or absorbs the noise from the engine. Most Mount Juliet car owners don’t realize that we can actually customize the noise our car makes with a custom muffler. You can upgrade to a muffler that will make your car sleuth-quiet, or you can advertise your presence in Mount Juliet with a sassy rumble.
Mufflers can also rust or be damaged by road debris. But just because their main function is to dampen out engine noise doesn’t mean they can be ignored. If your muffler is leaking, you need to get it replaced quickly. Exhaust fumes need to exit through your tailpipe, not your muffler.
The exhaust pipe contains at least one oxygen sensor. The sensor monitors the oxygen content of the exhaust, which allows it to adjust the fuel-to-air ratio in the engine. This keeps your sedan engine running smoothly and maintains good gas mileage. So, besides keeping you and the environment healthy, a well-maintained exhaust system also keeps your sedan healthy. The tailpipe itself can rust or get damaged by road debris, so it needs a quick inspection once in a while, too.
The whole exhaust system is mounted on the vehicle with clamps and hangers. These clamps and hangers can come loose, rust or get dinged up by road debris. Remember that the gases in your exhaust system are hot, so the exhaust system itself gets hot. The clamps and hangers keep the exhaust system attached to the sedan, but they also prevent the heated components from touching things they shouldn’t. If you don’t inspect and replace broken, loose or damaged clamps, you may end up with melted wires, hoses or lines. And that can spell some expensive repairs.
You should schedule an exhaust system inspection as recommended in your sedan owner’s manual. Because this system is critical to your health and the health of your car, and because of its sophistication and complexity, you need to have the work done at a qualified service center such as Conder’s Automotive in Mount Juliet.
Maintaining your emissions and exhaust system is not just good auto advice: it’s good health advice for all Mount Juliet car owners and their families.
Whenever they hear the term “exhaust service,” most Nashville people think about exhaust pipes and mufflers. Well, actually, exhaust service at Conder’s Automotive is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced automobile manufacturers to come up with much more sophisticated ways to comply with environmental regulations.
Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your vehicle manufacturer recommends you have your emission system checked out by a qualified Mount Juliet exhaust technician regularly to make sure everything is working right – usually every 6 months or 10,000 miles/16,000 kilometers.
If your Check Engine light comes on, especially if it’s flashing, get your car looked at right away. Technicians at Conder’s Automotive handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Conder’s Automotive at 615-758-1515 to schedule an appointment if you experience these problems.
Let’s review the exhaust system. We will start from the top and start with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose, or a gasket is leaking, dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn’t leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.
Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and the environment into harmless carbon dioxide and water. It doesn’t require any maintenance itself. But eventually they wear out. You will find this out when your car fails an emissions inspection.
Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car’s sound with different mufflers – anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away.
The exhaust system is attached to the car by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.
Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.
Exhaust and emissions service covers plain old pipes and high-tech computers. It impacts everything from life and death safety due to exhaust leaks, to fine-tuning the sound of your ride.
