Boiling point doesn’t matter. That’s what the radiator pressure is for. To raise boiling points. Your car operates at 190. Straight water boils at 212. High speed fans kick on at 210-225. Adding pressure to a pressurized system will effectively raise any boiling point of liquids. Your car won’t run hotter or colder. That’s controlled by thermostat.
Antifreeze/coolants MAIN benefit is to prevent freezing when car is off and parked in cold climates.
I’m just pointing out that antifreeze is to not have your radiator freeze (or engine block) when parked. Antifreeze properties don’t really care about boiling point aspect of the cooling system. Since the radiator cap controls boiling points of liquids, not the actual liquid in radiator.
Yeah I do know what I’m talking about do you?
Why would coolant be a bit warmer? Are you aware that antifreeze suggests “non-freezing?” I’m sure you have heard that people can put water in radiator. People can pee in radiator. Doesn’t matter what’s inside for the liquid to transfer engine heat to radiator. Any liquid can basically work to take engine combustion temps and transfer it to radiator to cool off
The problem with piss and water in radiator is the freezing point. When you park your car, water will freeze at 32 degrees. Good thing there is antifreeze which has a way lower freezing point. That’s the main purpose of glycol. To not freeze
Coolant is only used for freezing!! Antifreeze is the name, which suggests a non freezing condition.
Coolant shouldn’t be thought for operating temp. Yes coolant boils at different temps then water, but the boiling point of any liquid inside radiator gets raised due to pressure in coolant system.
Antifreeze mixtures are really only used for freezing. To make sure your coolant system doesn’t freeze when car is parked. I think 65/35 still protects yo around -30 degrees. You will be fine with 65/35
That’s why I capitalized MAIN. The main benefit of antifreeze is lower the freezing point. The boiling aspect doesn’t truly matter since it’s a pressurized system. Yes it does raise boiling points but your thermostat and radiator pressures control the boiling points.
