By law, your Cadillac needs a fully functioning catalytic converter to help keep the air clean. But the remarkably complex inner workings of a converter can sometimes go awry, clogging up the release of air and fumes from your vehicle. This can lead to engine problems and dangerous fumes leaking into the cabin. Let’s take a look at three clear signs that it’s time to visit your local Cadillac dealer to repair or replace your cat.
Does Your Cadillac Need a New Catalytic Converter?
Your Engine Loses Power
When a converter clogs up, the airflow through your car is interrupted. This means less oxygen can enter the fuel-air mixture in the engine’s combustion chambers, which rapidly becomes unbalanced. As a result, your cylinders will be firing less efficiently, and your engine will lose power.
A loss of engine power means your acceleration will become sluggish and your fuel economy will drop. You might see black smoke emerging from your tailpipe. You’ll start idling roughly as your cylinders begin to misfire, and your Cadillac might even stall. You’ll also be given a warning of all this when the check engine light comes to life on your dashboard.
A Technician at Your Cadillac Dealer Can Diagnose the Problem
Engine performance problems can be caused by a faulty converter or several other issues. For example, your air filter might be clogged, your spark plugs or ignition coils might be malfunctioning, or your fuel injectors could be at fault. To be sure, it’s best to have a qualified technician examine your car and diagnose the problem.
You Smell Sulfur
When the chemical process inside your cat stops converting toxic emissions into less harmful gases, you’ll probably smell the difference. One emission in particular has a distinct sulfury stench similar to that of rotten eggs. Those sulfury fumes are also harmful to your health, so pay attention to your nose and have your cat inspected as soon as you detect a rotten egg smell.
You Hear Metalling Rattling
As it hangs underneath your vehicle, a converter can occasionally become battered or dented by a rock, curb, or pothole. When this happens, the delicate honeycomb mesh inside the stainless steel casing will often break or come loose and start to rattle about.
If you hear rattling from below, check under your car for visible signs of damage to the converter. Sometimes the converter itself comes loose in its brackets, which will cause an even louder rattling. You’ll most likely need an experienced technician to judge the damage to the converter and decide whether to replace it or not.
