Yes, Coolant=Radiator fluid in this context

I've seen plenty of them stuck shut. I don't know of any manufacturer that has a failsafe thermostat.

It's a mechanical part that unfortunately breaks.

Just thought I'd toss this out - straight water runs cooler than 50/50.

Yea but straight ice runs even cooler, it's just a little harder to circulate.

Just thought I'd throw these out:

1. If straight water runs cooler, is that because it pulls less heat from the engine?

2. Does straight water run cooler after 50k miles and all the internal parts have a nice coat of corrosion on the surface that slows down thermal transfer?

3. Does straight water run cooler when the temp gets up to 225

??? The last time I tested my coolant (13 July 05 before the Vintage Buckeye Run) it tested to -37*F/+265*F

Are you suggesting that straight water under pressure (Like a pressure cooker) runs at lower temps that 50/50? Does that mean that it never exceeds 212*F? where it would turn to steam? I am a bit confused by this statement??

Please explain.

Water under pressure would boil at a higher temp than 212*F. It also has a higher specific heat than a dilution. This means that it would absorb more heat than a 50/50 mix. The best cooling is from a straight water mix. Antifreeze is added to keep the water from freezing in the winter.

Antifreeze is also used for corrosion protection, which is pretty important on a all aluminium engine.

Does Redline Water Wetter offer anti-corrosion properties?

I understand it is the intramolecular and intermolecular hydrogen bonding on ethylene glycol that allows it to have a higher boiling point.
I believe water can only bond intermolecularly. Please correct me if I am wrong.
