How to Know When a Muffler Is Broken

A muffler is an important component of an engine’s exhaust system. The muffler is found near the back of a vehicle, and its purpose is to reduce the noise produced from the exhaust process. It also directs the exhaust gases safely out the vehicle’s system. Although manufacturers for regular checkups or replacement do not schedule the muffler, you should learn how to know when a muffler is broken because it does wear out or break. A defective muffler can cause significant noise pollution and pose a hazard for any of the vehicle’s occupants.
Steps
1. Know the risks of a defective muffler.
 If the muffler has a hole, it can cause dangerous gases such as carbon monoxide to leak into the cabin of a vehicle. This colorless, odorless gas is a product of the combustion process. Mild exposure to carbon monoxide can cause headaches, dizziness, and nausea. Prolonged carbon monoxide exposure can lead to unconsciousness and death.
 Many homeowners’ associations, cities, restaurants, and apartment complexes have laws against loud noises from defective mufflers. If you have a broken muffler, you may face fines or refusal of service until you get the muffler fixed.
 A damaged muffler can cause a car trip to be noisy and uncomfortable.
2. Listen to the sound of your vehicle. A broken muffler may cause the car to have a louder sound than before. Thumping or clunking may indicate that something is broken in the exhaust system.
 Some mufflers contain baffles to reduce the noise of the exhaust system. These may become broken or loose and cause rattling in a muffler.
3. Use a car jack to raise the car so you can examine the muffler. Inspect the muffler for any holes and rust. Visible rust on the outside may indicate an even worse problem on the inside of the muffler.
4. Observe the car while it is running, and look for unusual exhaust smoke. Thick, billowy smoke may indicate a damaged muffler.
5. Look for water dripping from the muffler. Although condensation in a muffler does occur and some manufacturers include a small drain hole in the muffler therefore, water dripping from several places may indicate that holes have formed from rust.

6. Check the temperature of the engine after the car has run awhile. If the car overheats, it may mean there are problems with your car’s exhaust system.
7. Take your car to a mechanic if you suspect your car has a defective muffler.
