Antifreeze comes in several formulas.

Propylene Glycol is non-toxic and can be used in fresh water systems. Some "PG" based antifreeze can be used in engines as well. For best performance, the antifreeze should have lubricants to protect the rubber impellers as well as corrision inhibitors for the metal parts in your cooling system.

Some antifreeze comes as a concentrate that needs dilultion 1:1 with water. We do not recommend this type. Unless the mixing water is warm and care is taken when mixing, the fluids may not fuse, and you can have pockets of low protection that can freeze.

We always drain the engine and other systems before flushing antifreeze through.
If you winterize toilet and other systems while the boat is still in the water, you must remember to open the thru hull fittings after haul out. Some raw water may still be in the intake. We leave these thru-hull valves open for the winter . Another "authority" insists on closing them so vermin cannot get in. They should have a protective screen, and we believe letting condensate drip out is preferable.

Ethylene Glycol is toxic and should only be used in Closed Circuit cooling systems (heat exchangers and radiators). In many states, using this type of antifreeze for the raw water side of your engine is illegal.
