I am thinking the first stop on a Cummins is the aftercooler??....then the trans cooler....THEN the heat exchanger. At least that is how it is on my Classic B series.

I have the SMX pumps on my boat. So I change every 2 years. It is NOT a fun job on either engine. It is easier to pull the pump and do it rather than jack around down there with those little screws. And guess what??? I carry an entire spare pump assembly with a new impeller in it. Suck on that Ted!!!!
