Exhaust Service

January 21, 2019 by Denver Express Car Care

Driving down the road or around town, we’ve all heard a car or truck that sounds like it needs a new muffler.  But there’s more to the exhaust system than just the muffler.  The exhaust system has three main functions:

 

  1. Safely get hot exhaust gas from the engine out the tailpipe.
  2. Treat the exhaust to remove harmful pollutants.
  3. Muffle the engine noise.

Exhaust gas is poisonous.  Drivers don’t want it getting into their passenger compartments.  Most of us know that 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 Express Car Care in Denver.  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.

Then there are the environmental issues to consider.  Exhaust gas contains a number of pollutants and particulates.  The catalytic converter scrubs some of those harmful substances.  Diesel vehicles have systems that 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.  Then there’s the muffler.

The beauty of getting a new muffler is that you can suit your own taste.  Some drivers want whisper quiet, some like a little rumble, and others like a roar.  Give us a call and let us know how we can help.

Exhaust ServiceQuestion:  My car failed its emissions test – what do I need to do?

Express Car Care Answer:  First of all, let’s make this clear:  A leak in your exhaust system could be deadly!  If Denver drivers smell exhaust in the passenger cabin or hear an unusual exhaust sound, they should get their exhaust system checked and repaired as soon as possible!  Talk to your helpful Express Car Care service adviser. And this is information is critical – Carbon monoxide in your exhaust is odorless, colorless and tasteless and can be fatal to you and your passengers!  So don’t delay if you suspect an exhaust leak.

There could be a number of reasons for a failed Colorado emissions test,  so some important diagnostic work is in order.  A common reason for Denver drivers is that the catalytic converter has failed.  The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn’t cheap for an auto owner.  Many people stop there – but the converter failed for a reason.  There may be any number of engine-run conditions that led to the failure.  It would certainly be smart to have your Express Car Care service professional diagnose the cause so that you don’t end up with another expensive catalytic converter replacement down the road.

And let’s not forget that check engine light that so many car owners ignore.  It might just be illuminated for a critical condition that could lead to catalytic converter damage.  Have your service professional get to the bottom of any check engine light situation.
