Can you weld an EGR tube?
Either type of welding would be fine as long as the tube is cleaned and still thick enough. And it could be thinning out in other spots so check it before wasting time fixing one spot when there are other spots that will open up soon, squeeze it with pliers and poke it with screwdriver if in doubt about an area.
What does an EGR tube do?
EGR tubes direct exhaust gases from the exhaust manifold through the EGR system. The tubes ultimately recirculate the gases back into the combustion chambers to be burned again.
How do you know if your EGR tube is bad?
EGR valve symptoms can vary, however, the most common symptoms of a faulty EGR valve are explored below:
- Your engine has a rough idle.
- Your car has poor performance.
- You have increased fuel consumption.
- Your car frequently stalls when idling.
- You can smell fuel.
- Your engine management light stays on.
Can you drive with a broken EGR tube?
Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.
How hot does an EGR tube get?
The maximum temp at the egr flange end of the tube was 339.8 F. The maximum temp at the plenum flange was 178.2 deg. F. The silver solder melts at 700 deg F.
How do you test an EGR tube?
A vacuum-controlled EGR valve is easy to test with a hand-held vacuum pump (see the image). If the EGR valve opens and the vacuum holds for more than a minute, the EGR valve works. If a vacuum diaphragm inside the EGR valve is leaking, the vacuum will drop. Once the vacuum is released, the valve should close fully.
How much does it cost to replace EGR tube?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle’s year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.
Is the EGR valve supposed to be hot?
It’s normal for the EGR valve to get hot, but if it’s stuck open, it can cause the engine to stall.
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 are the symptoms of a bad EGR tube?
Rattling noises from the engine Another symptom of a bad or failing EGR tube is rattling noises from the engine bay. If the EGR tube breaks or comes loose, it can cause rattling noises as a result of the metal tube vibrating. The noise may be quiet at idle, and become more noticeable when accelerating.
What happens when the EGR valve fails in a car?
The EGR tube is the passage through which the vehicle’s exhaust gases travel from the exhaust back into the intake. When the EGR solenoid or valve is opened, exhaust gas is allowed through the tube, and into the engine for consumption. When the EGR tube fails or has any issues, it can cause problems with the operation of the EGR system,…
What kind of noise does an EGR make?
If the EGR tube breaks or comes loose, it can cause rattling noises as a result of the metal tube vibrating. The noise may be quiet at idle, and become more noticeable when accelerating.
