    It would be great if anyone could recommend a company in the Rhode Island area that does ultrasonic cleaning. I'm looking to have my jacket water aftercooler cleaned. thanks

    Still looking, any non marine companies? Niemiec is a bit pricey.

    They charged me $150 for each cooler. I posted the same question a few years ago. Only place I could find. They came out like new.

    I'd pay that, they quoted me a lot more.

    Can you find a radiator company or a heavy trucking company that can just boil it in a degreaser?

    Tony Athens recommended an ultrasonic clean specifically. I suspect at one time this engine ate a filter because of an exhaust leak. It may be more than gunk in there, IDK. Pricing out new as an option also. Never had it off so, I can only guess what it looks like.

    I gotcha, I'd take it off and see what it looks like. Being JWAC, makes one half of the cooler super easy to maintain, and a good de-greasing might be all you need. Something to look into as another option anyway. What are you planning on running that Cummins at for a cruise? If money is an issue that should go into the equation as well.

    This boat is heavy and its my first novi. Its sweet spot is hull speed which is about 7 kts at 1300rpm.

    I really don't understand why a professional ultrasonic cleaning is necessary....I also thought a good bath in parts cleaner could clean it up. I'm still looking at cost and how long it will be out of service.

    Bill-how was the gasket under the AC, did you reuse it?

    Oh man, if youre only running it at 1300 rpm youre barely building any boost, which means no heat, so ultrasonic cleaning would be a waste of money. I would absolutely give it a good degreasing, or give it to a radiator shop to boil and call it good.

    That makes sense to me. I start rolling coal when she starts using fuel, this is what instigated the whole thing.

    Does the coal go away or does it stay after the engine gets up to speed? Id pull the A/C and see what it looks like and then go from there. Also look at the compressor side of your turbo, I had an old Isuzu that had worn compressor blades from crappy filters and wouldn't build up boost. Could be other things going on.

    stays brown/black after 1400ish. I have boost but only at the only upper rpm range. I understand this CPL would have benefited with a turbo that started producing more boost lower in the RPM range.

    Turbo looks ok, some wear at the outer parts of the blades where they sweep back instead of run straight, also dirty, and it's hard to tell what the clearance is between the blade tips and the compressor housing. There could be other issues contributing to the engine rolling coal, but as far as this thread is concerned I'd definitely just boil the cooler.

    My Volvo had low boost and soot on the transom after every trip. My turbo had a lot of corrosion on the exhaust side and I decided to replace the exhaust elbow with a high rise design and put a new turbo on. I did the exhaust but had the Volvo tech do the mechanical work including teardown back to the head. I had some minor leaks at the hose ends also. They recommended ultrasonic cleaning.

    I wanted to get everything checked out and know it was right. Despite the BS story from the prior owner about how the coolers had been cleaned every 3 years one of them had never been apart.

    Mine looked like new after the cleaning. I was told the internal passages don't get completely cleaned by boiling. If you're doing it every 3-4 years that probably works fine but if you think they're really clogged then it might be wise to spend the $$$.

    Pulled it yesterday, cleaned in Simple Green and Brake Clean. It was a lot cleaner than I expected which is good and bad.

    Genius that aftercooler looks pretty good i have about the same one on my 270 6bta. Just went through this myself i would not suggest ultrasonic cleaning since i had bad results. Brake cleaner through the fins and soaking with maine incredible pink worked great. plug that intake hole and fill through the fins, let it sit a while and purge out with good pressure water.
