What is an exhaust gas recirculation (EGR) tube replacement?

An EGR tube replacement ensures your car is running as clean and efficiently as possible. A mechanic will do a computer diagnostic and check all of the vacuum tubes related to the EGR valve. If necessary, the mechanic will replace the EGR valve and any cracked or broken vacuum tubes.
The EGR valve takes some of the engine gas and sends it back into the engine through the intake manifold. Most cars are required to have an EGR valve to decrease emissions and increase fuel efficiency. Getting your vehicle serviced regularly can help you avoid severe damage to the EGR valve.

How to replace an exhaust gas recirculation (EGR) tube

Your mechanic will replace the EGR valve by doing the following:
  • Run a diagnostic of the car’s computer codes
  • Inspect vacuum hoses connected to the EGR valve system
  • Test the exhaust gas recirculation transducer
  • Check for any blockage on the EGR port
  • Remove the old EGR valve and gasket
  • Replace with a new EGR valve and gasket
  • Clear the computer codes and re-run the diagnostic

When do I need to replace my exhaust gas recirculation (EGR) tube?

If you notice you’re getting lower gas mileage or if you’ve failed an emissions test, it may be time to replace your exhaust gas recirculation (EGR) tube. You might need a new EGR valve if:
  • Check engine light is on
  • Idling is unstable
  • Car rattles when accelerating
This is a fairly common issue, so your mechanic should easily be able to fix the problem if you tell them what you’re experiencing.

How important is an exhaust gas recirculation tube replacement?

Your car will still run if there’s an issue with the EGR valve. However, a damaged valve will lower your fuel efficiency and send more emissions into the environment.
Many states and municipalities have emissions requirements that cars must pass to be on the road, so it’s best to get the car seen and repaired sooner than later.
