Meter exhaust gas back into the intake with the Standard Ignition Exhaust Gas Recirculation (EGR) Valve EGV703. It installs as a direct-fit replacement across a range of GM and Isuzu light trucks, including the 1986-1993 Chevrolet S10, 1986-1989 Chevrolet S10 Blazer, 1986-1990 GMC S15, 1986-1989 GMC S15 Jimmy, 1991-1993 GMC Sonoma, 1991-1994 Isuzu Pickup, 1991-1992 Isuzu Rodeo, and 1989-1991 Isuzu Trooper.
An EGR valve routes a measured portion of exhaust gas back into the intake, which lowers peak combustion temperatures and helps reduce the formation of NOx emissions.
Signs the original valve may need replacing include rough idle, stalling, or engine knock/ping. Because those symptoms can have other causes, diagnose the cause before replacing. If a failed EGR valve is the cause, this unit replaces it.
Manufacturer part number EGV703.
