No , the engine should be cool before adding any fluids to the engine cooling
system
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
Yes all automatics should be runnung when adding and most chrystlers should ne in Neutral not park when checking the fluid.
It lowers the freezing point.
( NO ) with the engine cool
Have you spilt some on the radiator?
Yes
No , it's best to add coolant when the engine is cold
You dilute your antifreeze. If you buy prediluted 50/50 antifreeze, then you'll dilute it more than you're supposed to. If you buy straight 100% antifreeze, you're actually supposed to dilute it yourself by adding an equal amount of water to the antifreeze you put it. Your vehicle will be fine. Stop freaking out. Get a coolant flush.
Yes. Never add pure antifreeze. Pure antifreeze will actually freeze before a 50/50 mix. Add coolant that is a 50/50 mix of antifreeze and distilled water. You can buy it already pre-mixed.
Adding antifreeze to your radiator is a physical change because the antifreeze retains its chemical composition and properties when mixed with the water in the radiator. It does not undergo a chemical reaction to form a new substance.
increases, and lowers
The antifreeze provides corrosion protection until the corrosion package is " used up " and it raises the boiling point and lowers the freezing point of the water
