Like I pictured above, the plates are two piece and simply allow the coolant to flow. If you buy a one piece, it’s typically not going to be a flow through. I do not think it really matters. As @AZsurveyor mentioned, it helps with a few degrees but nothing major.From what I understand, it goes under the block off plate which allows coolant to flow through those ports or holes allowing the coolant to run a tad cooler although I don't know of anyone actually doing that?
@JTredway @HeavyAssault would probably know more about that assembly
This must be a newer version of EGR block off plates
So once the EGR is fully removed for permanent maintenance, the bottom plate goes on and indexes into place. The top plate bolts on and is sealed with an o-ring providing the flow-through channel for coolant to pass through. There’s also a ln air bleeding port on the top plate to release any potential air in the system depending on how the system was drained and re-filled.
Flow-Through
Non Flow-Through
In the “non” the coolant had no route to flow. Just “dead heads” into the plate.
