How to Replace an EGR Valve

by Contributor

Replacing the exhaust gas recirculator valve on a vehicle is a fairly easy job. You do not need to be an automobile expert to perform this task. If you have a basic idea of what's under your car hood, you can save money by doing this yourself.

Disconnect the car battery. Locate the EGR valve. You may need to refer to the owner's manual.

Unhook the air supply hose, vacuum hose and all electrical connections. You may need the screwdriver for this.

Remove the EGR mounting bolts with the socket wrench.

Unbolt the EGR valve from the EGR tube with the wrench. Use a wide-mouthed wrench, which works best for this.

Look at the EGR valve. If there are holes in the valve, it definitely needs to be replaced. If there are no holes, you may opt to clean it by spraying a half can of carburetor cleaner into the valve. Let it sit, then use a gasket scraper, putty knife, small drill bit or long wood screw to scrape out the buildup in the valve.

Install a new gasket and EGR valve if a total replacement is due. Attach all hoses, wiring and bolts that were previously removed.

Reconnect the battery and test drive the car.
