Recirculate a measured portion of exhaust gas back into the intake and help keep combustion temperatures in check with the Standard Ignition Exhaust Gas Recirculation (EGR) Valve EGV534. It's a direct-fit replacement for a long list of 1984-1993 GM cars and light trucks, including the Buick Century (1984-1988 and 1990) and Skylark (1984-1988), Chevrolet Celebrity (1984-1990), Camaro (1984-1986), S10 (1985-1989 and 1991-1993) and Astro (1985-1987 and 1989-1990), GMC S15 (1985-1989) and Safari (1985-1987 and 1989-1990), Oldsmobile Cutlass Ciera (1984-1990), and Pontiac 6000 (1984-1990), Fiero (1984-1988) and Firebird (1984-1986) — see the Buyer's Guide tab for the full list of 29 applications.
Signs the EGR valve may need replacing include rough idle, stalling, engine ping or knock under load, and a check engine light tied to EGR flow. Because these symptoms can have other causes, diagnose the source before replacing; if a failed EGR valve is the cause, this unit replaces it.
Manufacturer part number EGV534.
What does this EGR valve do?
It recirculates a metered portion of exhaust gas back into the intake, lowering peak combustion temperatures to help reduce NOx emissions.
What vehicles does the EGV534 fit?
It's a direct-fit replacement for many 1984-1993 GM applications, including Buick Century, Chevrolet Celebrity and S10, GMC S15, Oldsmobile Cutlass Ciera and Pontiac 6000. See the Buyer's Guide tab for all 29.
What are the signs of a failing EGR valve?
Rough idle, stalling, engine ping or knock under load, and an EGR-related check engine light. These symptoms can have other causes, so diagnose before replacing.
Is any gasket or hardware included?
The facts don't list an included gasket or hardware, so consult the vehicle service information for the correct gasket and fasteners and whether any may be reused.
Will replacing the EGR valve fix my rough idle?
If a failed EGR valve is the cause, this replaces it; but rough idle has other possible causes, so diagnose the underlying problem before ordering.
