If you overfill the reservoir and radiator with antifreeze, it will generally expand as it gets hot and spill out of the reservoir. When it does that, it will usually spill onto the hot engine and create "smoke".
you can use as much as you like as it makes the car run cooler
All the time
You'll usually see a "Fill Line" on the reservoir bottle, fill it to there.
the antifreeze runs through all your water lines in your car . . . . you put it in your water tank or radiator
You can run up to 75 percent antifreeze without any trouble. -------------------------------------------------------------------------------------------------- Actually , Ford states not to exceed ( 60 % antifreeze )
antifreeze antifreeze a fifty fifty micture of water and antifrez is best
In the coolant reservoir when the engine is cool.
Nothing Nothing
antifreeze keeps your car from overheating, it flows thru your radiator hose, without it your motor would blow
That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
The smoke is unburned fuel, if a truck or car smokes to much it means there is too much fuel being put in the firing chamber, this may or may not be desirable.
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
