I have a 3600 diesel. I replaced a freeze plug (the one that requires a split - thanks Ford engineering) this summer and there was a lot of gunk in the block and tried to flush it but she was in two pieces in my garage so not able to really flush it. I just put water in it, ran it as needed, called it good. Well then the cold snap down here in GA (25-32F at night)and I remembered that she only had water and sludge.
When I flushed with coolant flush, I expected more crap than I got. The bottom hose was not even warm but the upper was warm. She has never run hot. I carboarded the radiator just to get it to temp today thinking my thermostat was bad. My IR thermometer had the top of the radiator at 150F but not higher so I was getting some return water from the engine. There were some odd chunks of stuff in the summer sludge. I wondered what the hell something like that was doing in the engine and now I think I know what it was.
Did these 3600s have a plastic impeller? How do I verify the impeller? Can I see it by removing hoses? I's like to diagnose without tearing into if it can be avoided.
