If you’re like most people, you probably don’t know much about catalytic converters. In fact, a lot of drivers are unaware of the role that “cats” play in their vehicle. A catalytic converter is a device that helps to reduce harmful emissions from your car. When they start to fail, it’s important to know what to look for and how to replace them. Here’s a guide on how to tell if your catalytic converter needs replacing, and what to do about it!
What is a catalytic converter?
A catalytic converter is a device that helps to reduce harmful emissions from your car. They have been on vehicles since the mid-1970s, and are an important part of keeping our air clean. When they start to fail, it’s important to know what to look for and how to replace them.
Why do catalytic converters fail?
There are a few reasons why catalytic converters fail. The most common is due to age and wear-and-tear over time. This can cause the catalyst inside to break down, which results in less effective emissions control. Other causes include damage from water or other liquids that have gotten into your exhaust system (such as oil), or damage from road debris.
How do I know if my catalytic converter needs replacing?
There are a few signs to watch for when it comes to catalytic converter failure. One of the most common is a distinctive “rotten eggs” scent coming from your car. This is caused by emissions that aren’t being properly controlled, and is a classic sign that your converter is starting to fail. Other signs include a decrease in fuel economy, a failure to pass an emissions test, or loud rattling noises coming from your exhaust system.
Why do I need to replace my catalytic converter?
If your vehicle fails an emissions test due to a bad catalyst, you will be required by law not only pay for repairs but also retrofit or repower with cleaner technologies. This can be costly and time consuming, so it’s important that drivers act quickly when they notice signs of failure.
How long do catalytic converters last?
The average life span of a catalytic converter is around 100,000 miles or eight years, depending on driving conditions and maintenance habits. The best way to ensure your vehicle’s emissions system remains in good working order throughout its lifetime is by following manufacturer recommendations for routine service such as oil changes, tire rotation and coolant flushes.
What are some common catalytic converter replacement mistakes?
The most common mistake is not replacing it soon enough. When drivers notice signs of failure, they may wait too long to get their vehicle serviced or repaired by a professional mechanic. This can result in higher emissions output from your car which can lead to costly fines.
Another common mistake is not having the correct replacement part. Many drivers try to save money by replacing their catalytic converter with a universal or aftermarket part. This can be dangerous and may not meet emissions standards, which could lead to even more expensive repairs down the road.
What should I do if my catalytic converter fails?
If you think your catalytic converter may be failing, it’s important to take it to a mechanic right away. They will be able to diagnose the issue and let you know what needs replacing in order to get your car running again!
