How do you remove the EGR tube from an intake manifold?
After all electrical lines have been removed, spray some penetrating oil onto the nuts and bolts that connect the EGR tube to the EGR valve and the intake manifold. This will loosen them and permit you to remove the tube without stripping the nuts or bolts. Step 6: Disconnect the EGR tube from the intake.
What should I do if my EGR valve is blocked?
You will need to clean the EGR valve of the blockage using the following steps: Disconnect battery. Remove sensors or clips. Loosen bolts holding the EGR valve. Use a EGR or Carburetor Cleaner to spray the valve and hoses. Reconnect the battery.
What happens when an EGR tube becomes loose?
The EGR tube is an important component of the EGR system. When it is damaged, leaking, has become loose, or has become disconnected, it will cause the vehicle to operate inefficiently. Proper diagnostic checks should be completed to determine the exact cause of the symptoms.
What does carbon cleaning do to the EGR valve?
This process is often referred to as “carbon cleaning” as the process cleans the EGR valve and any supporting connections, including the EGR tube. It removes excessive carbon buildup, which is the root element found in fuels. On most vehicles manufactured after 1991, there are multiple sensors that monitor the effectiveness of the EGR system.
What happens when an EGR valve is not working?
The exhaust gas recirculation (EGR) tube is an important component of your EGR valve. Without this tube working properly, your valve won’t be able to operate as it should. Once this happens the vehicle is no longer able to recirculate the exhaust gases as it should, and allows them to escape into the air.
How does an exhaust gas recirculation ( EGR ) tube work?
Smog is essentially nitric oxides, or unburnt fuel in the form of NoX. The EGR system is able to take unburnt fuel that comes from the exhaust manifold and recirculate the molecules into the intake manifold. This allows the engine to consume less “new fuel” which increases fuel economy and also significantly reduces vehicle emissions.
How much does it cost to replace an EGR tube?
$115.96 – $570.03. Average rating from 21 customers who received a Exhaust Gas Recirculation (EGR) Tube Replacement. The exhaust gas recirculation (EGR) tube is part of your vehicle’s EGR (exhaust gas recirculation) system and is part of the EGR valve.
After all electrical lines have been removed, spray some penetrating oil onto the nuts and bolts that connect the EGR tube to the EGR valve and the intake manifold. This will loosen them and permit you to remove the tube without stripping the nuts or bolts. Step 6: Disconnect the EGR tube from the intake.
Do you need to replace the EGR pipe?
Even though the functioning of the EGR system may seem complicated, replacing the EGR pipe won’t be. You may need to remove various air intake parts to get at the EGR hose Then you’ll need to unbolt the EGR tube from the exhaust manifold and separate it from the EGR valve, unbolting it and disconnecting the associated vacuum hoses.
Why is my EGR tube not working properly?
The exhaust flowing through it can leave behind residue that builds up in the tube. The high heat of these gasses may also damage the tube, causing leaks. In either case, the result will be that the EGR system doesn’t supply exhaust gasses to the engine when it’s supposed to.

What should I do about carbon build up around the EGR valve?
If there is a lot of carbon build up around the EGR valve, you may also want to just save yourself some time and replace it with a new one. Clean out the entry port. The entry port is where the valve tubes connect to the engine (usually the intake manifold) while the EGR valve is off.
Where are error codes stored in an EGR system?
On most vehicles manufactured after 1991, there are multiple sensors that monitor the effectiveness of the EGR system. If a problem is discovered by these sensors, it will trigger an error code to be stored in the engine control module (ECM) of the vehicle.
How to test an EGR valve with a hand mirror?
As you do this, watch the valve diaphragm movement. Use a small hand mirror for this, if necessary. If the stem or diaphragm doesn’t move, disconnect the thin vacuum hose from the top of the valve. Place your finger on the opening of the vacuum hose you just disconnected. Increase engine rpm again as you did in the previous step.
What’s the best way to replace an EGR valve?
Step 5: Spray the connections on the EGR valve and intake manifold with penetrating oil. After all electrical lines have been removed, spray some penetrating oil onto the nuts and bolts that connect the EGR tube to the EGR valve and the intake manifold.
