??? I think you are trying to find engine antifreeze. I have never tried that, I always have used the pink propylene glycol sold all over the place to winterize water systems in boats, vacation cottages, and RVs. It has no ethylene glycol in it, you can drink it. I use the same stuff for the engine and the water tanks. This is not engine coolant and is only used for winter layup. Someone on a forum somewhere also explained that while ethylene glycol is quite poisonous to DRINK, it does about the same harm as propylene glycol if dumped overboard.

You might think that, but it is not. Recochem used to make a propylene glycol engine antifreeze here that was widely sold under various brand names, notably Prestolite, but they don't anymore. It came as a something of a shock when it was no longer available. Some automotive speed shops have a version that is imported from the States, but it is absurdly expensive. None of the former retailers I talked to, including Canadian Tire, could give me a reason for its disappearance from the marketplace. There is sometimes available a premium plumbing antifreeze that contains propylene glycol in some proportion but it doesn't say in what proportion, and it still contains ethyl alcohol. In short, it is difficult and expensive to find here, and for no apparent reason. I have resigned myself to using the environmentally unfriendly ethylene glycol.

IIRC, the better one would be Propylene Glycol, but it is not easily available. Btw. if AF drains, it is only better (you don’t have to worry about water diluting the AF.

Won't antifreeze drain out of your engine when you take the cover off the water pump?
