Exhaust Service at Air Park Auto Service

Apr 22nd, 2019

Driving around Ashland, we've all heard a car or truck that needs a new muffler. But there's more to the exhaust system than just the muffler. The exhaust system has three main functions:

  • Safely get hot exhaust gas from the engine out the tailpipe
  • Treat the exhaust to remove harmful pollutants
  • Muffle the engine noise


Exhaust gas is poisonous. Ashland residents don't want it getting into their passenger compartments. For example, carbon monoxide can be deadly. That's why you should never run your engine in a closed garage. If you have a leak somewhere in the exhaust system, exhaust could get into the passenger cabin and make you sick or even kill you.

If you smell exhaust in the vehicle, roll down your windows and get it inspected at Air Park Auto Service in Ashland. You may smell or see exhaust coming from the engine compartment or under the vehicle if you have a leak. Sometimes the sound from an exhaust leak is loud and obvious. Sometimes it's a ticking sound when you start the engine that goes away as you drive. That could be a small crack or a bad fitting that leaks when it's cold but seals up when the metal heats and expands.

For those vehicles with wheel bearings that can be accessed, we can do some preventive maintenance. You may have heard the phrase "pack the bearings." With this procedure we remove the bearings, carefully clean them and inspect for any imperfection or wear. If the bearings can be reused, we reinstall them and pack them with grease. If not, we put in new bearings. Check your owner's manual or ask your Ashland, VA, service advisor at Air Park Auto Service if your bearings can be serviced, and if so, when it should be done.

Now, let's address the environmental issues. Exhaust gas contains a number of pollutants and particulates. The catalytic converter scrubs some of those harmful substances. And diesel vehicles have systems to deal with soot.?Catalytic converters?eventually wear out and need to be replaced. They're expensive so you want to help them last as long as possible by keeping the fuel system clean and replacing your air filter. These components need to be tested for proper functioning with an emissions test from time to time. And that leaves the muffler.

The beauty of getting a?new muffler?is that you can suit your taste: Some Ashland want whisper quiet and others like a little rumble. And some Ashland like a roar.Give us a call.
