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.
Being an aircooled engine, the cooling medium is air .It does not need antifreeze
A 2002 Chevy cavalier 2.2l needs 10.7 (qts) of silicate free antifreeze.
Mix it half and half with the water.
1 1/2 gal.
11 5/8 quarts
Typically a 50/50 mix of clean water and antifreeze will protect down to -34 degrees. Have your local auto parts store test your antifreeze.
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".
According to the Owner Guide the engine coolant system capacity is ( 18.0 liters / 19.0 quarts ) So if using a 50 / 50 mixture of antifreeze and preferably distilled water : You would need ( 9.0 liters / 9.5 quarts ) of antifreeze
too much anti freeze has nothing to do with heater. but you should always keep the antifreeze level under the MAX indicator on the reservoir because you need the space for the heated antifreeze to expand and to siphoned back when it's cooled down.
