When you refill your coolant use ONLY distilled water to mix.

I usually use R.O water that's for our salt water reef tank but, a few times on the road I had no choice to use crappy water.
Other than needed height for a big radiator, why did the originals slant back, or even today's cobras ?

Any reason not to use the pre-mixed 50/50 coolant?

That's exactly what I do. The only downside is that you're pissing away a little bit of dough, but frankly, I find it easier than mixing distilled water in with the coolant. |

A bit more for coolant is just a bit more water over the dam...

If a few bucks makes my life a little easier it's a few bucks well spent.  |

Yes, the same reason I don't mix my own; water transfers heat best. |

I like a 30% coolant mix with distilled water. With 50/50 you lose a bit more heat rejection capability that our cooling challenged Cobra's so do need. The 30% gives adequate freeze protection, rust inhibitors as well as pump lubricants.
