Powerstroke EGR Valves
Shop Powerstroke EGR Valves from ForDiesels.com. The valve is a crucial part of the flow process.
Exhaust gas travels from the passenger side exhaust manifold through a metal pipe to the EGR valve under the intake manifold. When the engine rpm increases above idle, the computer opens the EGR allowing exhaust gas to flow from the EGR through a pipe that runs along the underside of the passenger-side intake manifold and into the manifold.
The EGR cooler is the long pipe from the EGR valve that is fitted with a radiator core on the inside of the pipe. Engine coolant passes through this small core and cools the exhaust gas passing over and around it.
