What’s the pink good stuff? Around here, pink antifreeze is used for winterizing potable water systems. It is not the good stuff for engines (at least not mine).

So since I got the boat(C&c-3 35) 2 months ago, I have been doing all the typical engine Maintinance. I never touched an <https://www.cruisersforum.com/forums/tags/engine.html> engine before with absolutely no experience. Got the <https://www.cruisersforum.com/forums/tags/boat.html> boat and started to follow the manual from <https://www.cruisersforum.com/forums/tags/oil%20change.html> oil change, filters, impellers etc. However, my <https://www.cruisersforum.com/forums/tags/engine.html> engine now heats up and the idiot temp <https://www.cruisersforum.com/forums/tags/alarm.html> alarm comes off. I have a yanmar 3gm30 that has been modified to be coolant cooled. My engine had unknown green <https://www.cruisersforum.com/forums/tags/coolant.html> coolant, I went ahead and flushed it and replaced it with the pink good stuff. While troubleshooting the overheat, I checked the impellers again(both new), pumps rotate with no problem or leak and sea <https://www.cruisersforum.com/forums/tags/water.html> water ofF the <https://www.cruisersforum.com/forums/tags/exhaust.html> exhaust and no leakage anywhere. So I think it has to be the coolant circuit. Something weird is that the hose from the <https://www.cruisersforum.com/forums/tags/heat%20exchanger.html> heat exchanger to the <https://www.cruisersforum.com/forums/tags/pump.html> pump until the thermostat, stays cold. But from the thermostat to the engine block and the last hose from block to the <https://www.cruisersforum.com/forums/tags/heat%20exchanger.html> heat exchanger is really hot. All hoses are replaced and checked for blockage. Is that an air block? If so, how can I bleed the system? Couldn’t find that anywhere. Also after the engine cools, I opened all the hoses to check if they have flow on them, and they all had coolant except these last 2 from the engine block to the heat exchanger. Is that normal? Should I fill them up manually with coolant to try to get rid of any air blockage? Last but not least, I may have trouble shoot the engine so much, and now I see steam that comes off or close by the 1st cylinder. Also a lot of blue smoke from the <https://www.cruisersforum.com/forums/tags/exhaust.html> exhaust. That never happened before. Did I mess up big time?
