Standard Ignition EGV733 EGR Valve

Standard Ignition EGV733 EGR Valve

Standard Ignition EGV733 is a mechanical exhaust gas recirculation (EGR) valve built for direct replacement on select Cadillac applications. It uses stainless steel valve components, a polyester-reinforced silicone diaphragm rated for thermal aging resistance up to 200degC, and a reinforced gasket for a complete replacement.

Compatible With 1990-1993 Cadillac DeVille, 1990-1992 Cadillac Fleetwood, 1990-1992 Cadillac Commercial Chassis, 1990 Cadillac Eldorado, 1990 Cadillac Seville, and 1993 Cadillac 60 Special. The Standard Ignition EGV733 is a fitment-based solution for restoring EGR function on these vehicles.

Key Features

• Mechanical EGR valve with no connector
• Stainless steel valve components for durability
• Polyester-reinforced silicone diaphragm resists thermal aging up to 200degC
• Reinforced gasket included for direct replacement
• 1 hose connector and 2 bolt holes
• Direct-fit design for straightforward installation

Detailed Description

The EGV733 exhaust gas recirculation valve is engineered to regulate exhaust flow back into the intake stream, helping maintain proper emissions-system operation on supported Cadillac models. Its mechanical design, stainless steel construction, and heat-resistant diaphragm support consistent valve movement under elevated engine temperatures. This part cross-references 2-36004 and 4F1085 for the same application.

Use Standard Ignition EGV733 when replacing a worn or sticking EGR valve on 1990-1993 Cadillac DeVille, 1990-1992 Cadillac Fleetwood, or other listed Cadillac applications. The included gasket supports a complete replacement at the mounting surface, and the direct-fit layout helps match the original installation points.

What It Helps Fix

• Rough idle caused by an EGR valve that is sticking open or closed
• Emissions faults related to improper exhaust gas recirculation flow
• Driveability issues from inconsistent EGR operation
• Vacuum-related EGR performance problems on mechanical systems
• Exhaust flow control concerns on aging Cadillac emissions hardware

Installation Notes and Tips

• Verify the vehicle uses a mechanical EGR valve with no electrical connector before ordering
• Confirm the mounting pattern matches the 2-bolt design
• Inspect the hose connection and surrounding vacuum lines during replacement
• Clean the mounting surface before installing the included gasket
• Check for carbon buildup in the EGR passage if the original valve failed from restriction

Quality Assurance

Standard Ignition builds this valve with stainless steel components and a reinforced silicone diaphragm to support durability in high-temperature exhaust environments. The reinforced gasket is included to support a proper seal during replacement.
