How to Clean a Diesel EGR Valveby James Melzer
The ERG valve helps exhaust gasses flow through a diesel engine. When the ERG gets clogged with carbon build-up, it will cause problems with the engine such as loss of power, smoking, or surging. Once it is removed, however, cleaning the ERG valve on a diesel engine is an easy process. The process takes a few minutes to complete, and the valve can then be reinstalled to maintain the quality of the engine's performance.
Scrape the carbon build-up off of the ERG valve with a small flat-head screwdriver and a stiff nylon brush.
Remove the two O-rings and base gasket on the ERG valve with an O-ring removal tool.
Soak the ERG valve in carburetor cleaner. Do not allow fluid to penetrate the weep valves located beside the base gasket. Submerge it until the remaining carbon is removed.
Rinse the ERG valve with injection fluid after the carbon build up has been removed.
Dry the ERG valve with a clean cloth or compressed air. Replace the gasket and O-rings. The size of these depends on the size of your ERG valve.
