Perfect, Thanks.

I 'm going to be adding Wicked Diesels Coolant By-Pass Kit when I change the coolant. Within the month i'll be doing both.

Just so everyone is aware, the coolant bottles do not list the temperature that a 60/40 mixture protects against. They only list the 40,50 and 70 percent coolant data. A 60/40 mixture of G-05 and distilled water will provide freeze protection down to -62° F (-52° C).

So then 50/50 would probably be at least -35/40*?

Dr.Dizzle

A 50/50 mixture provides protection down to -34° F (-36° C).

I'm pretty sure that even though you may want more than 50% antifreeze for it's freezing prevention, the less water you mix the less cooling capabilities remain. Straight water is excellent at cooling a system. Nothing is better than good ole H20.

Dr Dizzle,
My Zerex G 05 bottle does have a chart and it says this:

% up to down to

50% -34F 265F

60% -62F 270F

70% -84F 276F

That's not supported by the Zerex chart trik, and also it's not what my own tests show.

I have 2 buckets of raidiatior drain. First drain, and the second drain. The first drain with all the coolant, I tested at 270F. The second drain, with only residual coolant was barely 250F.

Maybe I should try a stove top experiment for the fun of it.

Anyway, Just FYI.

I think the water is the best coolant is a thing that used to be true. Now days with all the additives that help heat transfering this isnt the csae any more.

Dr.Dizzle

Thanks!

Thanks guys... I stand corrected... maybe the new stuff is different than the old or the stuff I was taught when I was younger was incorrect...

I was taught the same thing trik. I think it used to stand true, but that was before the days of some of these new chemicals they use for heat exchange.

I grew up around drag racing and went to the track quite often. Was on my uncles pit crew. I remember many drag cars that ran no coolant and only water and was told it was because it was a better conductor of heat AND if a car overheated on the track, it was easier to clean up water than coolant. I am sure that you are right as far as new chemical formulations. Although I work with water for a living... and I know that a straight water setup for cooling a building is more efficient than one with glycol or safecool. You need around 8-10% more chiller capacity when using a water/antifreeze mix. And yes in the next month or so we have to drain all the chilled water pipes and coils and run "safecool" thru the coils for freezing protection. It's a lot of freakin work.

I have attached a Zerex G-05 technical data sheet for your review. This document contains specific information relating to the G-05 coolant formulation as well as the automotive specifications this product meets or exceeds.
I feel that this information may benefit those members considering a coolant purchase, make an informed decision, especially those still covered under a factory warranty.
