How to Clean the EGR Valve in an Isuzu Rodeo

by Alibaster Smith

The Isuzu Rodeo's EGR valve recirculates exhaust gasses back into the combustion chamber for more complete burning. The Rodeo uses a canister-shaped EGR valve that is electronically controlled (as opposed to mechanically operated). The valve will naturally become dirty over time because of the carbon building up inside the valve from the exhaust. The contaminants will cause the Rodeo's valve to stick. This will prevent the valve from fully opening. Once you've removed the valve from your Rodeo, you'll need to clean it.


Turn the EGR valve upside down so that the valve opening is visible. The top part of the EGR valve is where the electrical connector is, and the bottom is where the mounting holes are.


Inspect the valve opening for carbon buildup. Then, fill the valve opening with carburetor cleaner and allow it to soak for several hours. Be sure that you do not get any cleaner onto the electrical contacts of the valve.


Dump the carburetor cleaner out into a bucket and clean the valve opening with a bendable pipe cleaner brush. You may also need to chip away at hard deposits with a small flat-head screwdriver.


Spray the valve opening again with carburetor cleaner and dump the cleaner out into the bucket.


Wipe the valve off with a rag and reinstall the valve when it is dry.
