EGR delete question
I have a set of ceramic coated manifolds, y pipe and both up pipes at the house. On the up pipe that goes to the EGR cooler I cut off the elbow patched the hole so its now smooth (so no more EGR flow). I might be installing these in a couple weeks or so and I was wondering when I put that delete pipe on do I have to plug (cover the hole) the cooler?
I don't think it will hurt anything because air is usually forced into the cooler and circulates and that's it unless you bust it.
But I figured I better ask before I do it.

Todder,
Yes it is recommended to plug the hole, since coolant is still flowing through the EGR cooler, if the cooler leaks you will have coolant running out of the motor. If the hole is plugged, then the coolant is still contained in the EGR cooler and no driving issues will occur. A freeze plug will fit in the hole IIRC.

So I need to get a freeze plug from the dealership and I shout be good?

now just a question because im new to the diesel world, but I was talking to matt at spartan about deleting the egr cooler and from what i understand if you disconnect the exhaust pipe to the cooler, and you have a cooler leak, the motor can suck coolant into the intake, if I understood him right.
So wouldn't plugging it just pressurize it from the motor heat and force even more coolant into the motor?
just my 2 cents but im sure im mistaken

remember not to just cap them off, as you need this flow of coolant since it has other duties to perform besides the egr ...
