Stus-List Coolant change in 2QM15
Derek: I have a Yanmar 2GMF.the engine has several 'drains' for the engine coolant which will empty by gravity. Each drain is opened by loosening what looks like a 'wing nut' and each drain fitting has a small diameter rubber hose attached which is useful to direct the coolant into a container for proper disposal when opened. Very easy job to do if you have the same setup which you should. Rob Abbott AZURA C 32- 84 Halifax, N.S.

Re: Stus-List Coolant change in 2QM15
I did this last year on my westerneke. There is a how to article on the marine how to web site. Anyway, I drained the engine because I had to replace the hoses going to the water heater heat exchanger. I didn't know what was in there and didn't want to risk mixing 2 different types of antifreeze. I disconnected hoses on the front of the engine and used a bucket and one of those pumps you attach to a drill to pump clean water out of one bucket into another. The engine has rather low hours and all looked pretty clean. I flushed for a while with tap water then, flushed again with distilled water. You never want to leave tap water in any engine. Then I pumped through the antifreeze distilled water mix. Closed it up and topped it off. It was actually pretty straight forward and took less than an hour.

Most of the coolant should come out by gravity. If you have a fresh water heater that is heated by the engine you may find it convenient to disconnect or tap one of the lines running to it. You have glycol coolant which "should" be captured and disposed of properly - Even the "eco" friendly propylene glycol. Once the majority of the coolant is out I would flush it with a fresh water supply "garden hose". They also make flush chemical additive which I would use after the freshwater flush. Then flush again with clean. Josh Muckley S/V Sea Hawk 1989 C 37+Solomons, MD On Thu, Jul 19, 2018, 6:27 PM Tortuga via CnC-List wrote: I have a Yanmar 2QM15 with a Sen-Dure heat exchanger.
