The exhaust system on a vehicle is more complex than most Boise motorists realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All Idaho 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 vital. We can help you with that at Napa AutoCare Boise in Boise.
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 Napa AutoCare Boise 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 Boise 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 Boise drivers 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 Boise 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 Napa AutoCare Boise in Boise.
Maintaining your emissions and exhaust system is not just good auto advice: it’s good health advice for all Boise motorists and their families.
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 Napa AutoCare Boise auto advice for Boise car owners, 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 Boise 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 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 vital that Boise auto owners 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 critical that exhaust pipes get a diagnostic examination regularly.
The catalytic converter is the next critical 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 Idaho. Call Napa AutoCare Boise at 208-323-9292 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 essential for damaged mufflers be replaced immediately at your Boise automotive service center, especially if they are leaking. Not only will the extra noise annoy your Boise 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 critical 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 pricey 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 important 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 Napa AutoCare Boise in Boise 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.
