The Importance Of Keeping Your Muffler And Exhaust System Healthy in Winter

What do Mufflers Do?

Most vehicle owners are unaware of what mufflers do. A defective muffler can cause excessive noise pollution, decreased fuel efficiency, as well as lowered engine performance. It also has the potential to harm the environment as well as the occupants of the vehicle.

Reduce Engine Noise

Your vehicle’s muffler is ideally a soundproofing device. It directs sound waves produced by your engine through a set of chambers and tubes that are designed to cancel noise for a nice quite engine.

Protect Vehicle Occupants from Fumes

There’s a lot more that goes on in your muffler than just noise cancellation. Your engine’s muffler also works to direct exhaust fumes produced during combustion out of the engine away from the occupants in the vehicle. In case there is a crack or a hole in the muffler, these harmful fumes could find their way into the vehicle. Exhaust fumes produced during combustion contain chemicals such as carbon monoxide that are harmful to humans.

Why do I need to take care of my Muffler during winter?

Exhaust Leaks Can Be Dangerous

A combination of exhaust gases produced in your engine during combustion is fatal to occupants in your vehicle. If by any chance, exhaust gases and carbon monoxide find their way inside your vehicle, it can be quite a challenge to detect, resulting in drowsiness, impairment, and even death. During the cold season, it’s important to have your vehicle’s exhaust system examined by a qualified auto repair mechanic for corrosion or damage to identify potential leaks.

Avoid the Possibility of Stalling

During winter, it’s important to always make sure your vehicle is free of ice or snow and debris before running your engine. When temperatures are below zero, there’s always a possibility of ice, debris, or snow getting stuck in your exhaust system. When your exhaust system blocks without enough room to get out through the tailpipe, it will begin to back up into the vehicle’s cabin, forcing the occupants of the vehicle to breathe in harmful fumes.

Extra Time Warming Up

Just like the vehicle owner, during winter, your vehicle takes a little bit longer to warm up than usual. Meaning, the first few minutes are the hardest for your automobile. When it’s cold, and your vehicle doesn’t take enough time to warm up, collected water vapor isn’t able to burn off. Also, salt-sprayed on roads during winter season and water can accumulate and corrode the exposed parts, resulting in rust. When the weather gets better, it’s advisable to wash your vehicle thoroughly to get rid of this combination of winter road grime.

Water is Harmful to the Exhaust System

Preventing water contact on your exhaust system is practically impossible. When water and exhaust fumes combine, they form corrosive acids that are potentially dangerous to the metal parts of your exhaust system. It’s very difficult to detect corrosion that leads to exhaust leaks on several parts of your exhaust system; therefore, it’s important to have your vehicle examined by a professional and experienced mechanic.

Signs Your Muffler Needs Replacing

Increased engine Noise

The moment you notice an increased exhaust noise from your vehicle, it’s normally a sign that your muffler needs replacing. When your vehicle gets louder, it also starts to feel sluggish. Most of the time, its because the muffler has been separated from the rest of the exhaust system. Alternatively, rust or impact from potholes or bumps may have created a hole in your muffler. Watch out for rattling or vibrations from underneath your vehicle; it could mean your muffler needs replacing.

Decreased Fuel Economy

Most of the time, your vehicle has decreased economy or is running hotter; it could be a sign that your muffler is rusting part. When this happens, your vehicle’s exhaust gases can not escape normally, and your engine has to work harder, resulting in poor fuel economy.
