Green antifreeze or coolant as some call it.

50/50 premix doesn't work anyway......

You can't get all the water out the block after flushing.

So you end up with something like 40/60 (antifreeze/water) when using premix.


I always look up the cooling system capacity to figure out how much full strength antifreeze to put in. Top it with water.

That is a very good point. I remember I used to do that when I was young and smart. But then got lazy and have mixed 50/50 and filled it on. But not used to buy premixed.

But thank you for getting me back on track
