How Many Catalytic Converters Does A Lincoln Navigator Have? (The Answer)

Today’s cars are very modern and fuel-efficient, yet there is some emission from every vehicle. Catalytic converters help to reduce the emissions from the internal combustion process. If the catalytic converter is damaged or the system is malfunctioning, emissions will increase.

Every car has multiple catalytic converters, and you must know the number when you need to change or clean these emission-preventing devices. Lincoln Navigator vehicle comes with two exhaust banks, each with one catalytic converter. You can locate the catalytic converters quickly after going through our article here.

The catalytic converter burns off the remaining fuel and prevents pollutants from entering the atmosphere. The converters use a process that involves a catalyst reaction to release carbon dioxide and water in the form of vapor or steel.

In this process, heat is also given away. It is mandatory to have a catalytic converter in every vehicle, and over the past decades, they have improved their efficiency. 

How Is This Number Identified? 

The Lincoln Navigator Engines Come with 2 exhaust manifolds and pipes, which allow admission from the back of the vehicle. Usually, a 4-cylinder engine or two-cylinder engine may have different numbers of catalytic converters.

Vehicles with more powerful engines need more exhaust manifolds as their emissions are also higher. Each exhaust pipe takes the admission out through a catalytic converter. Most cars may have only one exhaust pipe leading to a single converter, but at the same time, Many cars have two or more in-line catalytic converters, even up to 6.

What Are Cylinders And Banks In The Engine?

The engines are divided into two parts called banks. The first cylinder is located in bank one, which is closer to the front part with bank 2 behind it. In-line engines have 3 cylinders in each Bank.

It is essential to know the location of these banks because then you can address the errors in the catalytic converter or emission sensors. Most users mention that the Lincoln Navigator comes with one catalytic converter for each bank.

You Can Buy An Appropriate Catalytic Converter

An OEM replacement for the original replacement for the catalytic converter will be costly. That’s why many people try to buy a cheaper version of the converters.

Surprisingly, most catalytic converters for different cars are similar and can be fitted in many vehicles. The basic structure of the converter remains the same, and you just need to check the size of the pipes according to the system you have in your car. 

You can easily buy a catalytic converter and replace it if the existing one gets damaged. You can bypass the exhaust assembly process using an inexpensive catalytic converter, but all the bottles on the market are not equally good. You must find one that complies with the GPA regulations and comes with a warranty. 

The Lincoln Navigator has a 2.5-inch pipe, but you can check it before buying one. The original catalytic converters in the Lincoln have some exhaust piping and assembly installed. You may remove the old converters by cutting the mouth and attaching the new one with secure clamps.

The first replacement may be more complex as the converter must be removed mechanically; hence you can seek professional mechanical help. After this, you can also replace the catalytic converters by removing the clamps and attaching the new ones. 

A Car Can Have 3 Or 4 Catalytic Converters

Vehicles with more powerful engines and more cylinders will have more exhaust pipes because their emissions are also higher. For example, a car or a vehicle with more cylinders will have more pipes with two converters for each pipe. 

Some people may confuse a three-way catalytic converter with three converters. Usually, the cars come with one or two catalytic converters, but if there are more powerful engines, the car may have even three or four converters. More converters simply translate to fewer emissions as they catch even the smallest particles of smoke and pollutants. 

As mentioned above, Lincoln Navigator comes with two catalytic converters, one for each exhaust pipe system. These converters may cost $1500 or more with the entire system. At the same time, you can buy generic catalytic converters for less than $200, but you will have to cut the original one out to install the new one.

Why Does A Car Need More Catalytic Converters?

The Lincoln Navigator is a powerful car with 4 cylinders and two inland catalytic converters. This helps reduce the emissions level and also fits with the number of banks in the engine. Even the old exhaust system and converters may fetch you some money in the scrap market. 

Lincoln Navigator catalytic converters get damaged due to some reasons. If the engine misfires, it produces a lot more heat, and if there is more pressure in the engine, it may also trap heat and particles in the catalytic converter. Poor emission control and reduced mileage will let you know that the converter is not functioning efficiently. 

People say that driving without a catalytic converter is alright. However, it is against the regulations, and you would be harming the environment in the process. You may also pay some fines if caught without a functional converter. Hence, it makes sense to fit the converters immediately.

Summary 

The Lincoln Navigator needs at least two catalytic converters. The powerful engine needs one converter for each exhaust. You can buy a complete exhaust and catalytic converter system and replace the old one when needed.

It is mandatory to have these converters in the car and not advisable to drive without a working converter. You must follow the regulation to avoid paying charges or fines and be considerate to the environment at the same time.  

If you cannot invest so much money, then you can look for an inexpensive compatible version on the market. However, remember that this will involve a little more effort as the old system will have to be cut out and removed before connecting the new catalytic converters.
