Re: Need Onan MDL4 heat exchanger/exhaust manifold.
I am looking for a good used assembly if possible, I believe mine has a crack allowing exhaust pressure to enter coolant tank. Please let me know. Thanks for the help.

Re: Need Onan MDL4 heat exchanger/exhaust manifold.
Thanks for the replies everyone, I attached a photo I had. I will be down the boat next weekend and get a better one. I need the coolant, exhaust manifold, heat exchanger Assembely. Part in the top of the photo. Also anyone have a source for the gaskets? It is horrible that Cummings does not support anything. They tell you I can give you a price on new unit. I will never purchase a new onan.
Thank you in advance!

I have found the members of this site to be super helpful with issues I have had with my Onan, they have parts sources, as well.

I just want to thank Wild Blue for sending me his old heat exchanger at no charge. What a awesome guy. I can’t get over such a act of generosity. I will have to pay it forward to some one else. Thanks.

Re: Need Onan MDL4 heat exchanger/exhaust manifold.
I have the same vintage genny on my boat and was wondering how many hours are on your ONAN?
(In other words, when can I expect a similar issue?)
