Hello All,
I had my heat exchanger out for clean and painting. When I went to put her back together, I was questioning myself on whether the rubber sealing washers for the 3/8 bolts go on the inside of the plate or the outside. When I looked at the large rubber gasket between the HX body and end plate, there looked to be an indentation the size of the small screw washer so I put it there (on inside between gasket and HX body).
When I ran the engine for a quick start up, my attention went to a diesel leak at the injection pump bleed screw not the HX. Yesterday I noticed antifreeze under engine and I haven't had time to rerun and trace leak. Of course there is at least 4 other places for a coolant leak, just second guessing the bolt washer?

K- and how does that answer Paul's question?
Noah /Paul : The "O" ring /gasket for the bolt goes on the inside. Just like Ken's Web Site picture shows.

Inside being on the inside of the end cap and outside of gasket... Nice photo!

Great, that's the way I installed. I have pulled the exchanger at least a couple of times before and this is the first time I have had a leak was why I was second guessing that washer. Again, I haven't taken a good look at the 4 hose connections, probably needing a tighten here or there.
Thanks -k
