Simple Answers from Express Car Care: Exhaust Service

Question:  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.
