nonsense!! nothing in your cooling system will rust from water alone! otherwise the 50/50 solution of water would start the rusting process from day 1.DTASFAB wrote:That's a great way to rust out the radiator
what causes rusting is peoples failure to change the fluids on time.
race cars and race bikes ONLY run water(with a lubing agent). cars on the road in super hot climates ONLY run water, since its the best conductor. again, nothing in your cooling system will rust from water alone! you only need anti-freeze to lube seals, and prevent rusting. you can get all of these properties from many products that are top-quality and race-track approved.
it depends on your mix. 50/50 is great from some, and not good for others. if you live in arizona, new mexico, texas, florida etc, you can easily drive around with 70/30. if you live in really-really cold climates you could drop your mix by 60-40 and have little to negative affects. A 50/50 mix will give you protection down to -33 degrees. if you dont live in temps like that, its safe to 'play' with your mixture.and have the fluid freeze up at the same time.
your engine coolant has NOTHING to do with your cvt. your cvt has its own fluid, that goes into the bottom of the radiator to cool the fluid down from the incoming colder air. the channels and fins from the engine coolant dont even touch the channels from the engine coolant.since the CVT requires proper cooling from the radiator in order to not go limp.
i have raced my racebike with only water (every race track requires ONLY water with a couple cap fulls of water-wetter for lubing agent; as coolant is too slippery and hard to wash off) in the dead of summer, with 90*+ temps, i have had the engine up into 12,000-18,000 rpm, screaming... and never a boil over or any issue. and i am not the only one. EVERYONE ran water as per requirement. cars included. and they ran HARDEven with low ambient temperatures, driving the engine hard without proper cooling of the CVT could cause it to overheat. A driver who is extremely light-footed could get away with having more water than coolant in the radiator.
if anything, Pure water has a higher heat capacity than any anti-freeze mix! hence why items like water-wetter & engine ice work so well at the track.
a 50/50 mix of antifreeze runs 12 degrees hotter than a 50/50 mix with water-wetter. 100% water with few cap fulls of water-wetter runs another 20 degrees cooler.
test were done:
The engine operated at 7200 rpm for three hours and the stabilized cooling system temperature was recorded and tabulated below:
Cooling System Fluid = Stabilized Temperature
50%Glycol Coolant / 50%Water = 228°F
50/50 with Water-Wetter = 220°F
Water Alone = 220°F
Water with Water-Wetter = 202°F
so tell me, does the 50/50(at 228F) or the water alone(at 220F) sound like better cooling?
