What is a EGR tube?

Asked by: Lawanda Reed
EGR Tubes. 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 fix a EGR tube?
Right about here leave about an inch here an inch here. And then I'll remove it with the extractor socket. And then there is a high-temperature hose that they make it's a rubber hose.
How much does it cost to replace an EGR?
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.
What happens when an EGR fails?
A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration and decreased fuel efficiency. It can also cause vehicle emissions to increase.
What does an EGR do on a gas engine?
External Exhaust Gas Recirculation (EGR) has been used on diesel engines for decades and has also been used on gasoline engines in the past. It is recently reintroduced on gasoline engines to improve fuel economy at mid and high engine load conditions, where EGR can reduce throttling losses and fuel enrichment.
Where is the EGR tube located?
The EGR valve is usually located near or attached to the intake manifold, with a tube running to the exhaust manifold.
Can car run without EGR?
It might affect the environment but it is not harmful to the engine. Some people are running for more than 50k km without EGR. The EGR is disabled in all remapping.
Does EGR damage engine?
So not only does EGR hamper performance by coating and then shrinking the size of the intake path, but it is also hard on engine oil, and even degrades the coolant that is used to cool off the exhaust gases passing through the EGR cooler.
Does EGR improve fuel economy?
The addition of exhaust-gas recirculation (EGR) has been shown to improve the fuel consumption of gasoline engines, either port fuel injected or direct injected, by reducing pumping losses and knock and eliminating the enrichment region.
Do all cars have an EGR valve?
EGR stands for Exhaust Gas Recirculation and virtually all modern cars, petrol or diesel, employ this technique to control pollutants in the exhaust via an EGR valve. Some use what’s called ‘internal EGR’, where there is no EGR valve as such.
What does a EGR valve look like?
So this EGR valve is in good shape you can also let it sit like this for maybe 30 seconds 45 seconds just make sure that's not losing pressure if you see something like this.
When should I replace my EGR valve?
There’s not one specific answer to how often an EGR valve should be replaced. Some will recommend getting it replaced every 40,000–50,000 miles. However, like with most other things in your vehicle, there is no mile number set in stone for when a piece of equipment will wear down and break.
