Spare parts are crucial for the smooth and reliable operation of any vehicle, whether it is a car, truck, or motorcycle. High-quality spare parts can help extend the life of the vehicle and prevent unexpected breakdowns and repairs.
One of the most important spare parts for vehicle emissions control is the catalytic converter or cat. This emission control device plays a critical role in ensuring that the air quality remains healthy. However, over time, it can fail, leading to various performance and environmental issues.
This article will explore the top signs of a failing cat and when to replace it.
Decreased Engine Performance
One of the most common signs of a failing cat is decreased engine performance. If your vehicle struggles to accelerate, has reduced power or torque, or is experiencing stalling or hesitation, it may be due to a clog or damage. It can occur due to a buildup of contaminants or damage from overheating.
Illuminated Check Engine Light
Another common sign of a failing catalytic converter is an illuminated check engine light. If your vehicle’s onboard diagnostic system detects an issue with the converter, it will typically trigger the check engine light. Various issues, including a damaged or clogged device, can cause it.
Reduced Fuel Efficiency
When a converter fails, it can cause a reduction in the fuel efficiency of the vehicle. If you notice that your vehicle is consuming more fuel than usual or your miles per gallon have decreased, it could be a sign of a damaged or clogged converter.. It can be caused by a buildup of contaminants that restrict the flow of exhaust gases and reduce the engine’s efficiency.
Unusual Exhaust Odors
A failing cat can also cause unusual exhaust odours. If you notice a strong smell of sulphur or rotten eggs coming from your exhaust, it may be due to a converter no longer effectively reducing emissions. It can be caused by damage or contamination.
Loud Exhaust Noises
A failing catalytic converter can also cause loud exhaust noises. If you notice a rattling or clanging sound from your exhaust system, it may be due to a loose or damaged converter, and it can be caused by damage from road debris or overheating.
Failed Emissions Test
Your vehicle may fail an emissions test. Emissions tests measure the levels of pollutants in your vehicle’s exhaust, and a converter that is not functioning properly can lead to increased emissions of harmful gases. If your car fails an emissions test, it’s essential to have your catalytic device checked and replaced.
When to Replace a Failing Converter?
If you’re experiencing any of the above signs, it’s essential to have your vehicle inspected by a qualified mechanic. Depending on the issue, your catalytic device may be able to be repaired or may need to be replaced entirely. Generally, replacing a converter as soon as possible is best to prevent further damage and ensure that your vehicle operates at peak performance.
In conclusion, a failing catalytic converter can lead to various performance and environmental issues. If you’re experiencing any of the above signs of a failing converter, you must have your vehicle inspected by a qualified mechanic and replace it as needed. By staying on top of your vehicle’s maintenance and addressing issues promptly, you can ensure that your car has been running smoothly and reducing harmful emissions for years.
