Your car, truck, or utility vehicle’s exhaust will smell like rotten eggs if the catalytic converter is going bad. This generally happens in automobiles that are 10 years old or older. Vielhaber’s Garage explains that the catalytic converter is the exhaust system part that changes toxic emissions into safe emissions before they are pushed through the exhaust system and out of the tailpipe. Aside from a rotten egg odor in the exhaust, here are other signs that your vehicle’s catalytic converter is going bad.
Dark Engine Exhaust
One indication that the exhaust has not been treated aside from the rotten egg odor is black engine exhaust. Normally, you cannot see the exhaust as it flows out of your tailpipe. If the catalytic converter is clogged or malfunctioning, it will be unable to treat the exhaust, and any exhaust that makes its way out of the exhaust system will be this dark color as a result. This can also mean that you still have toxic emissions in your vehicle’s exhaust, which makes it dangerous to drive your automobile.
As the catalytic converter continues to fail, it will overheat. Because the catalytic converter is located underneath your car, truck, or utility vehicle, this is the general area that will get hotter than anywhere else. This being said, a faulty catalytic converter can cause your engine to overheat because the heat it is generating rises into the engine. Unfortunately, your engine will continue to overheat until you get the catalytic converter replaced.
Your engine will also suffer from performance problems. This is primarily caused by a blockage in the catalytic converter that prevents the engine exhaust from exiting through the tailpipe. When this happens, the exhaust is unable to leave the combustion chamber, and, consequently, the combustion chamber is unable to fire fresh air and fuel. This will cause engine performance problems such as sputtering and hiccupping, as well as acceleration lag and hesitation.
Check Engine Warning
Finally, a malfunctioning catalytic converter will turn on the check engine light on your vehicle’s dashboard. This is because the catalytic converter does not have a light of its own to tell you that it is going bad. Rather, one of the reasons why a check engine light turns on is that the catalytic converter is having problems.
