Walker Products Exhaust Gas Recirculation (EGR) Valve P/N:570-5065
Walker Products 570-5035 exhaust gas recirculation (EGR) valve for the 2005-2009 Buick LaCrosse V6 3.8L and other vehicles sends a portion of exhaust gas back into the intake manifold and controls how much flows.
An emissions-related fault code can point to a sticking or faulty EGR valve, but other parts can set the same code. With the engine off and cool, look over the valve, its connector and any vacuum line for cracks, loose connections or heavy soot before you replace it.
The 2002-2005 Chevrolet Impala V6 3.8L and the 1999-2002 Chevrolet Silverado 1500 V6 4.3L, V8 4.8L or 5.3L also take this valve, one per vehicle, along with many other models. Open the "Vehicles it fits" section to check your exact model and engine. As an OE replacement, it goes onto the factory mounting points and connects to the original wiring and vacuum systems with no modification required.
