Gasoline, being a blend of different hydrocarbons does not freeze at any single temperature.The heavier elements solidify at between -200 and -300F, which is darn cold.If it is that cold outside I would not drive.
add to coolant recovery tank!!!
in the over flow tank
pour it into the overflow tank
It is no longer necessary to add just water to a radiator in newer cars like the 2005 Malibu. An antifreeze that is half water and half antifreeze is usually best. Add the 50/50 antifreeze to the radiator overflow tank. It should be a plastic, see through tank hooked to the radiator.
If the vehicle is cold yes but make sure you mix the antifreeze with water before you add it, 50-50 is the best mix.
If it is a small amount of water add a can of Heet to the tank and fill it with gasoline. If it has allot of water you will need to pump all fuel out of the tank, add a can of Heet and fill the tank.
If the Blazer is gasoline powered the antifreeze can be any kind that is for sale for gasoline powered vehicles.
To the overflow tank and if the radiator has a cap,you will need to fill it with the engine cold.
I doubt it. I think you have water in your tank because it's no way how antifreeze can go in your tank unless you puuted it there. So if you have water in your tank, just buy stuff which is called dry gas. And everytime when you fill your tank add required quantity. To get rid of water in your tank you will need to do that at least 3 times, it depends on how much of water you have.
Yes you can. When the car reaches a certain temperature it will suck it out. As a matter or fact most newer model cars they tell you to add it there.

You have a leak somewhere. If you can't see it, then possibly a cracked head gasket.
