Better? Maybe/maybe not. http://knowhow.napaonline.com/what-is-hoat-coolant-4-things-you-need-to-know/ Ethylene glycol isn't actually bad for the environment. It readily breaks down and degrades. It's just toxic to aminals should they ingest it. On the other hand, many other coolants may not

Dennis, is that any better than the ethylene gylcol standard, or the same but more environmentally friendly? Ron Wild Cheri C 30-1 STL On Thursday, August 27, 2020, 02:56:18 PM CDT, Dennis C. via CnC-List wrote: OAT coolant is pink.  OAT is an acronym for Organic Acid (Additive)

*OAT* coolant is pink. OAT is an acronym for Organic Acid (Additive) Technology which describes the type of materials responsible for the corrosion protection offered by a *coolant* of this type. It's still a marine and automotive coolant. -- Dennis C. Touche' 35-1 #83 Mandeville, LA

Re: Stus-List Overheating yanmar 3gm30

It was mentioned earlier, but bears repeating. Like the previous poster, I thought the pink stuff was for winterizing, not for engine coolant. I believe the pink stuff uses propylene glycol which is safe for drinking water systems. I thought the gold standard for engine coolant is still

Re: Stus-List Overheating yanmar 3gm30

Thanks everyone for the help here. Here is an update and what I did this morning. I took off beginning of every hose and blow in it to make sure there is no blockage somewhere. Then topped every hose with coolant manually. Some of them specially the top ones off the engine block did have

Mazen, Have you checked the amount of antifreeze? Try adding a little. When was the last time that the antifreeze system was flushed and cleaned, including the heat exchanger? All the best, Edd ———- Edd M. Schillay Captain of the “Starship Enterprise” C 37+ | Sail No.:

Re: Stus-List Overheating Yanmar 3gm30

Just some thoughts based on our 3GM with Sender fresh water cooling 1) It is not normal for any hose to be dry 2) Check the fluid level in the Sendur heat exchanger. Run engine without radiator cap until thermostat opens allowing full coolant flow. Top off with anti freeze as

Re: Stus-List Overheating yanmar 3gm30

Hi josh, Yes sorry should have mentioned. Did these 2 steps as well. Thermostat is working fine and running the engine without the thermostat still didn’t help. Is that normal that the hose from the engine block to the heat exchanger is empty without coolant when I check it? MAZEN AZIZ

Re: Stus-List Overheating yanmar 3gm30

Sounds like you may have solved your own problem. If the one hose leading to the thermostat is cold and the other is hot then you should check that the thermostat is working. You can remove it and test in a pot of hot water. Or, you can even remove it and reassemble the engine (temporarily)
