Visited my boat this weekend to charge batteries and do some routine maintainence.
Located near Annapolis on the hard.
I checked the pink antifreeze in my water tanks and found it to be slushy. Then checked my engine compartment and saw the raw water strainer looked cloudy. Removed the lid to find that also was slushy. Had a new gallon left of the pink stuff which I checked and it was also frozen. Purchased the stuff at West Marine. The pink was not frozen solid but still it was frozen. Has anyone else experience this problem and how much damage is it likely to cause?
The pink stuff will slush but is not suposed to freeze solid and expand. The expantion does the damage. One question, did you use it straight with no water? If it is mixed with water....it WILL freeze.
Used the stuff straight from the bottle. Talked to Manufacturer yesterday. He said I should read the fine print. The bottle that says -50 degrees in large print on the front of the label is really only a 30%solution. The -50 means it will not break plastic pipes down to -50. It will not break copper tubing until it gets -12. It will normally freeze into a slush at +12. Next year I will be using something else. Will be keeping my fingers crossed till April.
Would if I could. It is too frozen. Plus I live 3 hours away. Again manufacturer assured me this is normal and will not expand enought to break any thing until minus 12.
I''ve used the -50 pink stuff in various winterizing efforts & have noticed the same thing. I now use propylene glycol ("evironmentally safe" antifreeze) and mix up the solution to my own dilution rates. I like it better. I think the -50 or -100 stuff is propylene glycol-based. Mixing it yourself gives you better control. Considering what freezing & possibly splitting equipment can cost...control is a good thing.
Be careful with the green ant-freeze. If your engine overheats, it causes a buildup in the heat exchanger. Yanmar recommends "EVANS" anti-freeze. Alot more expensive but is rated for 2500 hours, compared to 500 for everything else.
Ian,
I''m not sure I understand. The mix I make up is only used in areas where one would normally use the pink -50 & -100 "RV/Marine" type antifreeze(propylene glycol). Coolant/antifreeze in a diesel is a different question.
