All the time
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 )
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
You'll usually see a "Fill Line" on the reservoir bottle, fill it to there.
50/50 mixture.
You should use a gallon of coolant.
As long as the engine didn't overheat you should be O.K.
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 )
