Manufactured in 1992, the Nissan Altima continued the Nissan Bluebird line in 1955. The car is the larger, more powerful variant of the luxurious Nissan Sentra.
All Altima models in Nissan use the 150hp KA24DE straight-4 DOHC engine combined with a 4-speed or 5-speed manual gear system.
A car’s catalytic converter works by controlling the exhaust emission. Moreover, it helps reduce the toxic gases and pollutants caused by the exhaust’s internal combustion.
The converter turns these gases into less-toxic pollutants via redox reactions. The catalytic converter is essential because it reduces the gases emitted that cause global warming.
What Does a Catalytic Converter Do?
A catalytic converter utilizes a catalyst chamber to convert harmful compounds produced in the vehicle’s engine into safe gases, including steam. A catalytic converter splits the unsafe molecules in the gases produced by a car before releasing them into the atmosphere.
You can find a catalytic converter under your vehicle, which usually looks like a metal case with two pipes. The catalytic converter uses a catalyst and these two pipes to make the gases safe before expulsion into the environment.
What Will You Find Inside a Catalytic Converter?
A catalytic converter is usually made of platinum or metals similar to rhodium or palladium. The gases from the engine flow through a honeycomb-like structure found within the housing inside the case.
This compartment is lined with metals specialized for different jobs, all aimed at reducing the emissions produced by the engine. The two types of catalysts you might find in your Nissan Altima are reduction catalysts and oxidation catalysts.
How Many Catalytic Converters Does a Nissan Altima Have?
You will have two catalytic converters if you own a Nissan Altima with four cylinders. Knowing this is important since you should get the specific one needed for your vehicle. While some production cars may have one catalytic converter, some come with two.
Nissan Altima, for example, carries two catalytic converters. Generally, a vehicle with two exhausts has two catalytic converters. To confirm the number of catalytic converters on your Nissan Altima, you can check whether your vehicle has one or two exhausts.
Is a Catalytic Converter Worth Replacing?
Yes. You can do so if the engine has terrible gaskets or seals that cause unburned or antifreeze fuel to enter the exhaust system.
In that case, you should not replace your catalytic converter unless you have fixed the issue. If you change it without resolving the problem, the new converter will get damaged again.
How Much Does Catalytic Converter Cost?
There are varying prices for catalytic converters. The price range for catalytic converters for your Nissan Altima may cost $32 to $543 each. Depending on the material used, the price for each catalytic converter may vary.
Why Do Other Cars Have Three Catalytic Converters?
Because of their design, you can expect some to use the three-way catalytic converter system. That does not mean your car’s conversion system is wrong.
The three-way catalytic converter system oxidizes hydrocarbons and carbon monoxide while reducing nitrogen oxide.
Remember that its main purpose is to convert harmful gases into safe ones before sending them off into the atmosphere.
Can You Replace Just One Catalytic Converter?
Of course, yes. You may not need to replace both your catalytic converters simultaneously. If only one of them turned bad, you could replace one. Both converters work independently; hence there is no need to replace both.
How Do I Know if the Front or Rear Catalytic Converter Is Damaged?
Here are several points that you should note to determine if the front or rear catalytic converter needs replacement:
Firstly, you will notice a drop in your vehicle’s fuel efficiency. Take note of any change in your car’s acceleration. It will not speed up, and stepping on the gas pedal does nothing.
Also, starting your vehicle may seem harder than usual, or it may refuse to start at all. In the worst case, your car may fail an emissions test. Another sign is that your Check Engine or MIL light may appear on the dashboard.
Where Can I Find the Catalytic Converter on a Nissan Altima?
Catalytic converters are usually located underside the car. The catalytic converter is a part of your exhaust system and lodges between the muffler and the engine, and it looks like another muffler.
The Nissan Altima, like other cars, has a catalytic converter. You can find the two catalytic converters underside of the vehicle. If your catalytic converter has turned bad, you must check for underlying issues before replacing it.
You do not need to change both your catalytic converters if only one is damaged. You can replace only one since both converters act independently of each other.
If you do not fix your catalytic converter, it may decrease the efficiency of your vehicle and cause clogging, which may lead to other issues.
