How do you remove an EGR valve from a car?
Depending on your car’s make and model, the EGR valve may connect to a pipe coming from the exhaust manifold. Remove the pipe using a wrench. Alternatively, disconnect the pipe at the exhaust manifold. After removing the EGR valve, check the valve’s gaskets. Check for cracks or uneven wear and replace it if necessary. Otherwise, recycle it.
How often should you clean the EGR valve?
Check Engine light: On newer car models with electronic valves, the vehicle’s computer will trigger the Check Engine light when there is a problem with the EGR valve and passages. To avoid these headaches, clean the EGR valve and passages every 50,000 miles or ideally more regularly over the weekend at home.
What happens when the EGR valve is clogged?
The emission gas is recirculated back to the engine through the intake manifold to be re-burned in the combustion chamber. Normally, when the EGR valve is clogged, rough idle will occur. The EGR valve can get stuck open and there can be increased fuel consumption and smoke smell while driving.
Why does my engine make tapping noise when I clean the EGR valve?
Knowing how to clean EGR valve is a crucial step in solving these common engine problems. Noises from the engine: If the valve is stuck closed or passages become clogged, cylinders temperatures will increase, resulting in fuel ignites before the combustion. When this happens, you’ll notice a knocking or tapping noise coming from the engine.
What should I do after cleaning my EGR valve?
After all the ports are cleaned and the EGR valve is cleaned, reassembled all removed parts, clear any codes, and test drive to see if you have resolved your problem. Congratulations, you have now cleaned your car’s entire EGR system!
Where is the EGR valve on an engine?
EGR Valve Explained. The exhaust gas recirculation valve is an emissions-control device sitting between the exhaust manifold and the intake manifold. The EGR valve is typically closed when you start your engine.
How many years does an EGR valve last?
The EGR valve seems to have a lifespan of around 10 years of service. While replacing an EGR valve isn’t hard, yours might not be dead—just too filthy with carbon and gunk to function properly.
Why do I have carbon deposits in my EGR valve?
Since the EGR valve is a gateway for hot exhaust gasses, it is only natural for thick and murky carbon deposits to build up inside the valve. Over time, the carbon deposits will totally block the flow of exhaust gasses inside the combustion chamber, which incidentally will lead to serious engine problems in the near future.
