Meter exhaust gas back into the intake and help keep combustion temperatures in check with the Standard Ignition Exhaust Gas Recirculation (EGR) Valve EGV601. It installs as a direct-fit replacement across a wide range of GM trucks and full-size sedans, including the 2006-2009 Buick LaCrosse [V6-3.8L], 2006-2011 Buick Lucerne [V8-4.6L], 2006-2011 Cadillac DTS [V8-4.6L], 1998 Chevrolet Silverado [V8-5.7L], 2001-2004 Chevrolet Silverado 2500 HD [V8-8.1L], and 2006-2008 Pontiac Grand Prix [V6-3.8L] — see the Buyer's Guide tab for the full 25-application list.
Signs the original EGR valve may need replacing include rough or unstable idle, hesitation, engine knock or pinging, a failed emissions test, or a stored EGR-related trouble code. Because these symptoms can have other causes, diagnose the system first; if a faulty EGR valve is the cause, this EGV601 replaces it.
