Has anyone used a mix other that 50/50 in their truck?
I live in the freakin hot south and really am more concerned with overheating than freezing. Although due to global warming we did have a fairly cold winter (sarcasm added)
I found data that states that less antifreeze in a mix will actually drop the operating temperature of the engine, of course the trade off is less freeze protection.
30% antifreeze 70% water seems like it would enhance the cooling of the engine while still keeping my block from cracking in the winter.
You could also try adding water wetter. I don't see a problem with changing your anitfreeze concentration but I probably wouldn't go beyond a 40/60 split.
It is a waste of time to drop your coolant mixture cause the t/stat is what keeps the temp pretty much constant except under hard loads. Don't mess with the mix other then to add a bottle of Water Wetter or Purple Ice.
Here up north I've always used pure coolant without a problem. We have both hot and very cold climate. I suppose the higher viscosity could have a negative effect.
I know that the thermostat is set to open at a a particular temperature, dispersing the heat from the engine through the radiator.. If my recollection of Thermodynamics is correct; if the fluid being circulated can dissipate the heat more efficiently the engine should run cooler...
Am I missing something?
PS I am NOT a mechanical engineer, so would the more experienced mechanical types please chime in...
Well I can tell you this.
My 71 IIa was running hotter than I liked.
Checked the antifreeze concentration and it was high.
Cut it back to 70% water and it run much cooler.
I have been using Purple Ice, which is a very similar product.
