You should only have to check the level during your regular oil change. If it is a little low, it's probably just the water evaporating off of the antifreeze in an unpressurized reservoir. If the tank is pressurized, (radiator cap on the tank) it should, in theory, not lose any coolant between services. If the coolant regularly goes down to the add marks on the reservoir, you have a leak somewhere, most likely.
All the time
the antifreeze runs through all your water lines in your car . . . . you put it in your water tank or radiator
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
YES
Not if you want to keep driving the car!
some people have said you should and others have said you dont have to. I myself have never put antifreeze in the during installation in all the years i have worked on cars
50 / 50 mixture of antifreeze and preferably distilled water usually ( Ford says not to have less than 40 % antifreeze and not more than 60 % antifreeze )
no but if in the winter you do not put in the car the engine will freeze you can also use water during the summer No!
You can run up to 75 percent antifreeze without any trouble. -------------------------------------------------------------------------------------------------- Actually , Ford states not to exceed ( 60 % antifreeze )
