EGR Valve

The Exhaust Gas Recirculation (EGR) Valve reduces nitrogen oxides (NOx) that cause pollution by recirculating a portion of the exhaust gas back into the engine’s combustion system. Recirculating the exhaust helps cool the engine cylinders, resulting in less NOx gases. The EGR Valve opens and closes to control the flow of the exhaust gas so it can mix with the incoming air/fuel mixture and be burned off again.

Wells EGR Valves are designed to meet or exceed OE part specifications for fit, form and function.

The EGR Valve is generally located on or near the intake manifold.

If a vehicle is displaying one or more of the following symptoms, it may need a new EGR Valve:

• Rough idle
• Stalling
• Hard start
• Decreased power
• Decreased fuel economy
