The exhaust gas recirculation (EGR) is one of the most important components of your car's exhaust system. To make sure that it doesn't fail, it's important that its EGR Line is always in excellent shape. Once this component goes bad, there's no way that exhaust gases will be sent back to the gas chambers to be burned again. If you're dealing with a damaged EGR Line, you'd better get a top-caliber replacement right here at Auto Parts Warehouse. Made only of the best materials, you can be sure that our EGR lines will last for many years to come. When it comes to installation, our EGR lines can be installed using only simple tools. Unlike other EGR lines, our EGR Line has all the installation instructions written on its service manual to guide you during the installation process. So if you've been looking for reliable and dependable EGR lines, then it's time for you to get them right here at Auto Parts Warehouse. Here at our store, we make sure that you get what you purchased right away. Apart from that, you'll be getting your items in excellent shape after delivery. Put it simply, Auto Parts Warehouse will take care of you the minute you place your order here. If you want to experience world-class online shopping, shop only at Auto Parts Warehouse!

Choosing the Right EGR Line

The EGR line, along with the EGR valve, works to recirculate the exhaust gas into the intake manifold. This action does two things: it (1) effectively lowers the temperature in the combustion chamber, and (2) it reduces nitrogen oxide levels. Modern engines are equipped with cooling systems that lower the engine's temperature. New technology like fuel injection systems and oxidation catalysts keep the nitrogen oxide compounds to a minimum. But even with these newer systems, the EGR system still plays a very important part in reducing temperature and excess emissions. An EGR valve that is damaged can be cleaned with a carburetor cleaner and re-greased. An EGR line, however, needs to be replaced once it gives up on your engine. We have listed some tips on how to choose the right EGR line for your car.

Durability and warranty

An EGR line takes damage from the nitrogen oxide pumped through it back to the intake manifold. As such, it needs to be durable against corrosion, stress fractures, and carbon buildup that blocks the flow of gas. Some products have a flex joint that reduces the stress applied to the EGR line and minimizes the damage caused by heat and constant vibration.

A few other additional features dictate how durable an EGR line is. Look for an EGR line that includes sheathing to protect electrical components from heat damage. An EGR tube is usually made of stainless steel-this makes it resistant to the stress and corrosion applied to it daily. Look for an EGR line that carries a warranty of at least six months to a year.

Find one that fits

The brand of EGR line to buy depends on whether it will fit your vehicle or not. Local and online auto part stores can help you decide which EGR line to purchase given your car's make and model.

How to Install an EGR Line

Ever wonder where exhaust gas goes right after it's produced by your engine's combustion? The answer is this: it gets thrown back in to the combustion process again, right back into the air-fuel mixture. This is part of the effort of car manufacturers to reduce their car's nitrogen oxide emissions. And what makes this recirculation of the exhaust gases possible? It's a small component called the EGR valve, and a very vital part of this role is also played by the EGR line connected to the valve-this is where the exhaust gases pass through. In the process of performing this function, the EGR valve and line also lower the temperature inside the combustion chamber. A malfunctioning EGR line may cause rough idle or engine overheat. If your EGR line is busted and you need to replace it, here is a handy guide to help you with the process.

Difficulty level: Moderate

Tools you'll need:

  • Adjustable wrench
  • Ratchet and socket
  • Gasket and gasket sealer
  • Formula 409
  • Rag
  • Sharp putty knife

Step 1: Using a ratchet and socket, detach the negative battery cable. Remove the bolts holding the air intake system in place. The air intake assembly is usually located on top of the engine on one side.

Step 2: Locate the EGR valve. It is usually between one and two inches in diameter, and you will find it connected to the exhaust manifold via a metal conduit. The conduit is the EGR line. Unbolt it from the assembly.

Step 3: Pull the vacuum hoses from the top of valve. Remove all electrical connectors you see coming out of the valve. Look for the threaded fitting connecting the valve to the conduit. Use an adjustable wrench to turn the fitting counter-clockwise and remove it.

Step 4: Unbolt the EGR valve using a ratchet and socket and remove it. Pull the gasket out, then use a sharp putty knife to scrape off any gasket fragments. Make sure to leave no trace of any substances left by the old gasket.

Step 5: Since you have these components removed, it would be a good time to clean the surface of the mount with Formula 409. Wipe it clean with a rag. Do this thoroughly before proceeding to the next step.

Step 6: Apply gasket sealer to the new gasket. Put the new gasket in place. If you are installing a new EGR valve, do it now. Finally, bolt the new EGR line to the new valve, and reinstall all the components you have previously removed in reverse order.

The EGR line helps dilute the amount of nitrogen oxide from the combustion engine by expelling combustible substances. This DIY guide should make replacing your EGR line easy and could save you a great deal of money on mechanic's labor fees.
