Cummins heat exchanger removal Part 1 

I like how you replaced the old hoses as they should be replaced

Did you install a petcock at the antifreeze drain? Would make it easier and less messy next time the anti-freeze is changed.

Great video, do you have any footage on draining the coolant? I assume you released it from the bottom of the heat exchanger.

A 5/16 nut driver makes removing those clamps a lot easier.

Could you take one of the end caps off to inspect before doing the full restore?
