hi guys. at what temperature would the correct mixture of water and anti-freeze for the Z actually freeze?

i put about 100ml in a plastic tub, shoved it in a -15 degree freezer and it's frozen solid.

i also still think my running temp is a touch too hot.

would too thin a mixture cause it to freeze too early and get too warm? sounds like ive just answered my own question but i want to know your thoughts about it! :)

Coolant actually makes water less efficient at cooling than plain water. Coolant is just for winter to stop it freezing, but it does also have rust inhibitors.

Water and water wetter is best for summer, but then you have to drain down and put coolant in for winter.

If you dont have enough coolant it will freeze sooner. Theres a tool that you can suck your coolant into and it uses specific gravity to show how much coolant is mixed in the water, in tern this shows by floats what temp your coolant is safe to go to before freezing.

 

Hope some of that makes sense, lol, it did to me.

I dont think you need to be concerned about the freezing temp.

If you were to use it without any dilution with water the freezing temp protection is greatly reduced. Rough mixture is 50/50. Retry your experiment but mix it 50/50 with water and see what happens, if I am correct it will still be liquid. It also raises the boiling point of the water to protect the engine when it gets a bit hot.

 

The higher running temp is more likley to be because the engine will still be "tight" as the bearing/contact surfaces on your enginge are not bedded in yet and will be generating more heat untill they are "run in" and reach the correct tolerances, then it will run cooler.

 

have fun
