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.
How does the exhaust gas recirculation ( EGR ) system work?
The Exhaust Gas Recirculation (EGR) system takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help reduce nitrous oxide emissions.

How does the EGR tube work in a car?
The EGR tube acts as the main passageway of the EGR system, directing the exhaust gasses produced by the engine’s combustion from the exhaust manifold through the system, eventually recirculating it back into the intake manifold and back into the combustion chambers and the air-fuel mix to be burned again.
What does it mean when your EGR is not working?
Knocking, usually noticed as a pinging noise coming from the engine, can be another sign that the EGR system is not recirculating gasses properly. If there are problems with the EGR system, then the vehicle’s check engine light might come on.

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.
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’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.
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.

What causes a gas leak in the EGR tube?
The EGR tube can become clogged over time. 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.

What is the part number for an EGR valve?
Egr Valve Part Number: F37Z-9D475-C Other Names: Valve – Exhaust Gas Recirculat Description: Ranger. 3.0l.
Is there a warranty on Ford EGR valves?
We offer fast shipping on all in stock Genuine Ford EGR Valves and a Nationwide Ford Factory Warranty. Ford Parts Center carries everything Ford and all of our Ford Parts are Genuine. Description: EGR Valve Assy. E150-350 vans. 6.0l diesel.
The EGR tube can become clogged over time. 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.
How do you find the EGR valve in an engine?
Remove the vacuum hoses from the valve and inspect the lines. Spray carburetor cleaner inside the lines. Clean out the lines using a pipe cleaner if needed. If there are bolts attaching the valve to the engine, remove them. If the mounting gasket is in good shape you can set it aside and reuse it.

What can I do about a Clogged EGR valve?
If they clog, they can stay open all the time which leads to poor engine performance. There are several options available to you when it comes to the EGR valve. You can replace the valve with a new one. You can clean your valve with carb cleaner and refit it. Or, you can blank or bypass the valve completely. I chose to bypass the valve on my van.

Can a broken EGR tube be repaired by a handyman?
Now the EGR tube was over 100$ to replace, so i used this hose. Installed this about a year ago and still running it with no problems. There is a video on Youtube about it. The video is titled “How To Repair A Broken EGR Tube Or An Exhaust Air Tube” by handymanproblemfixer.
How does the EGR valve keep the engine warm?
The EGR valve recirculates a small amount of exhaust into the combustion cycle. The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up. Whether mechanical or electronic,…
What to do if your EGR valve is cracked?
Inspect the EGR valve for damage. Loosen any bolts fastening the EGR valve to the engine. Inspect the gasket lining the bottom plate of the valve. If it’s not frayed or cracked, you can reuse it.
