I'm looking to pressure test my 2011 cm2250 soon and want to check if the egr cooler is leaking. I know on rawze's video he takes off a plug or fitting on the rear of the egr on 871 but I don't see one on cm2250. Do I just take off the clamp and tube that connects to egr valve?
Same test, yes, take off the pipe that goes from the back of it up to the EGR valve. After you get it loose and try to get it away,... you will find a small stud screw that gets in the way of removing the pipe... I usually will cut it off with a dremel tool and cut-off blade, but you can work it out without doing this while cursing instead if you like.
