Detailed Product Description

The Dorman 904-5099 EGR valve features an electrically operated poppet mechanism that controls the flow of exhaust gases back into the intake manifold. This valve type includes a pressure relief function to maintain optimal backpressure, which is essential for reducing nitrogen oxide emissions and improving combustion efficiency. The valve connects via a single round male pin terminal with five female terminals, ensuring secure electrical connectivity. It mounts directly to the engine using three bolt holes, providing a stable and reliable fit. The included gasket ensures a proper seal to prevent exhaust leaks.

Common Applications and Issues Addressed

• Helps reduce engine knocking caused by excessive combustion temperatures
• Prevents increased emissions due to faulty or stuck EGR valves
• Resolves rough idling and poor acceleration linked to EGR valve malfunction
• Addresses check engine light codes related to EGR system faults
• Improves fuel efficiency by optimizing exhaust gas recirculation

Installation Notes and Tips

Installation requires removal of the old EGR valve and careful cleaning of the mounting surface to ensure a proper seal. Use the included gasket to prevent exhaust leaks.
