How much coolant does your car or truck hold? You want to have one half pure antifreeze and one half water. If you want to mix your own and if your car holds 4 gallons of coolant then you need 2 gallons of distilled water and 2 gallons of antifreeze. Or you can buy the kind of antifreeze that is already mixed called "PRE-MIXED COOLANT" at most part stores and just fill it up.
Your best bet is to visit a good auto shop (seller of antifreeze), and say "I want to buy enough antifreeze for a 1990 Chevy 5.7 truck".
