A car muffler is one of the most significant car components, yet one that can be easily ignored by many car owners. Besides reducing the exhaust noises, a car muffler safely directs the exhaust gases out of your vehicle's system. These gases can be poisonous and if they ended up in your car's passenger cabin, you, together with your passengers, could be at a serious risk of developing health-related issues from the inhalation. Therefore, knowing some of the signs that the muffler has developed an issue is very important. Here are some of the signs that you need to take your car to the auto shop for a muffler check-up.
When working properly, a typical muffler will work quietly. Therefore, if you notice a drastic change in the level of noise from your car's exhaust, it's a sign that your muffler is developing an issue. The noises could range from rumbling to rattling sounds. It's important that you inform your car mechanic as soon as you hear these noises because the louder the muffler will get, the more costly it will be to fix. Besides, if you continue driving with a faulty, rumbling muffler, you may cause issues to other areas of your car.
Reduced Fuel Efficiency
Are you spending more on fuel than you used to, even when the price per litre hasn't changed? There are many possible reasons why your car's fuel efficiency could have reduced, such as worn out spark plugs, bad tyres, or blocked fuel lines. However, if you have examined these and other possible causes and found them to be in good condition, have your mechanic check the muffler because it could be the culprit.
Bad smell is another common sign of a bad car muffler. When working properly, your car muffler should direct the exhaust fumes away from your car. However, if it develops an issue, like if it starts leaking, some of the fumes will be trapped inside your vehicle system. In most cases, bad smell is usually a sign that the muffler issue is serious and the best way to solve it is to replace it.
You can also check for signs of damage on the muffler itself. Inspect the muffler for any signs of holes or severe rust. Also, check whether there are drips of water coming from the muffler. However, when checking for water drips, remember that condensation usually occurs in car mufflers, and in most cases, some mufflers will even have a drain hole for it. However, if water is dripping from many places on the muffler, it could have developed holes.
