The EGR valve on a 6.6 Duramax diesel engine is responsible for recirculating exhaust gas back into the cylinders to help reduce emissions. Over time, carbon buildup can restrict the valve’s ability to function properly, resulting in decreased engine performance and increased emissions. The best way to clean an EGR valve is with a specialised cleaning tool, such as the EGR-PRO by Dieselcraft. However, the valve can also be cleaned manually with a brush and some solvent
How To Clean Egr Valve 6.6 Duramax
The EGR valve is a critical emissions control component on a Duramax engine. Over time, it can become clogged with soot and carbon deposits. This can cause the valve to stick open or closed, resulting in poor engine performance or even a failed emissions test. To clean the EGR valve, you’ll need to remove it from the engine and soak it in a cleaning solution.
The required tools for this project are a EGR valve cleaning brush, a can of throttle body cleaner, and a rag.
- Use a small
- Wait 5 minutes for the throttle body cleaner to break down any carbon deposits
- Spray throttle body cleaner liberally around the egr valve
- Label and disconnect the negative battery cable
-Use a brush or a vacuum cleaner to clean the egr valve -If there is any carbon build-up on the egr valve, use a wire brush to remove it -Make sure that you clean all of the ports and passages on the egr valve -Check for any damage or cracks on the egr valve and replace if necessary
Frequently Asked Questions
How Do You Clean The Egr On A Duramax?
