How long does a EGR valve last?
An average car’s EGR valve has a lifespan of approximately 10 years in service. Proper maintenance of the valve is a must if you want to avoid any performance related issues on your car. If you notice a smell of fuel that comes out from under the hood or rough idling, then it might be time to replace the valve.
Can the EGR valve cause starting problems?
The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases; into the intake manifold to get re-burned. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting.
What happens if you have a bad EGR valve?
When the valve is opened, exhaust gases are allowed through the vehicle’s EGR system to help control vehicle emissions. When the EGR valve has an issue, it can cause problems with the flow and operation of the EGR system, which can lead to increased emissions and performance issues. Usually, a bad or failing EGR valve will produce any these 4…
When to replace an exhaust gas recirculation ( EGR ) valve?
At this point the engine burns them again, so there are no emissions to worry about. Typically if your vehicle has been made in the last two decades, it is outfitted with an EGR valve. While there is no set mileage that it should be replaced, it is important to check that it is in good working order.
How does the EGR system work in a diesel engine?
The EGR system is a high pressure loop (HPL) system where a portion of the exhaust is taken from upstream of the turbocharger. The variable geometry turbocharger, among other tasks, ensures that the pressure difference between the exhaust and intake manifolds is positive to ensure adequate EGR flow is available when required.
How often should I Clean my EGR valve?
It is suggested that every 50,000 miles you have a carbon cleaning done, which is an air induction. This will clean out any carbons and sludge that is building in the air intake system and the engine. Once your EGR valve dies it will begin to affect your vehicle in a variety of ways, so it’s good to know what signs to watch out for.
