Not in the HX35, Cummins did use a water cooled turbo but that was only in generator and mining operations. Not in the dodge truck.
I have new theory after thinking on it.
I’d removed the intercooler boots prior to draining the block via the lower radiator hose. I popped radiator hose off and made a mess everywhere. I’m wondering if some coolant didn’t find its way into the intercooler that way.
