Re: [Cal_Boats] Yanmar 3GM30F--Changing Coolant

The green stuff is ethylene glycol and is poisonous. The orang/pink stuff is propylene glycol, and is actually used in food products - and performs just as well as the green stuff. The less poisonous stuff potentially leaking and sploshing about aboard the better, imho.

This is not that hard. My engine has had the green stuff for years and seems to do fine. I replace it every year. On the starboard side of the engine is a drain for the heat exchanger where all the green stuff can be drained, although this still leaves a lot in the engine block. You can flush with serial washes of distilled water which is fine while you are sitting at the dock. When I fill it, I fill as far as it will go, then let it sit for a while so the bubbles can come up, then fill some more. Finally I run the engine for a few minutes and then stop, let it sit, then fill it again. The overflow tank sounds like a great idea, but not sure where I would put it in the engine compartment. Not sure about the orange stuff. I have never used it and this is the first I have ever heard about it. If I am doing something wrong, please, someone let me know. Hope this helps.

I installed a small tank inside the cockpit locker higher than the water heater, which solved the problem. The tank has fittings for a hose from the water heater and a hose to the heat exchanger, along with its own “radiator” cap. Google for “overflow tank.” If that doesn’t turn up something, let me know, as I may still have the paperwork.

It has the "green stuff" as the coolant. I don't know when it was last changed, but I need to do this and have been dreading it. I've read that we need to use the "orange stuff" (with low silicates) in these engines(true? ) I've bought it, but have read that it is not compatable with green. So, I need to drain, flush, and refil with the orange. I do have a water heater, and it looks to be above the engine. So, I've heard that it is easy to get air in the system and cause overheating. Has anyone dealt with this and do you have suggestions? Thanks, Travis '86 33-2 "Vital"

The orange or gold stuff is a newer formulation for car systems, I think. My 2005 Ford Ranger uses a special gold coolant that's good for 5 years/100,000 miles. It looks yellow-orange to me. Most coolants intended for use in engines contain a variety of additives to prevent corrosion. I'd be reluctant to use a potable water variety unless I knew that it also contained an anticorrosion package. Chris Campbell

I thought gelling was only a problem in sub-zero conditions, but there is apparently quite a bit I still don't know. Good thing too, it gets boring when there's not still stuff to learn.

My Chevy came with orange coolant Dexcool II, I think. It dissolved some of the gaskets in my engine at a cost of $400 to replace. I am waiting for a check based on a class action suit to reimburse me.

A Yanmarhelp site led me to the orange coolant. Here's the link: http://www.yanmarhelp.com/s_coolant.htm. They talk about a specific orange coolant, Havoline #7994 extended life coolant. I temporarily posted the data sheet under "files" on the Cal site. This particular coolant has an ethylene glycol base. On the face of it, it looks good, but with John's automibile experience with what may be the same product, I don't know. Anyway, I still have to drain, flush, regardless of the coolant, since I don't know how long this coolant has been in the engine. My main concern was to try to avoid air locks which would starve the engine for coolant. I've gotten some good ideas here.

Another note, the pink stuff is also used for de-icing airplanes, because it is non-toxic. I used to get a facefull every so often when I miscalculated the wind direction. It's very sweet. Nothing like being in the bucket at 6am at 10 or 15 degrees defrosting a 737.
