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!
Being an aircooled engine, the cooling medium is air .It does not need antifreeze
50% Antifreeze and 50% water mixed together. The winter months you need a higher ratio of antifreeze to water and in summer you need the 1/2 and 1/2 ration. It is not suggested to run pure Antifreeze in your car or truck. You can find pre mixed in the jugs at most Wal-marts/Kmarts/Auto Parts stores.
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.
( Yes ) antifreeze in your vehicle provides corrosion protection for the engine cooling system ( the corrosion protection package does " wear out " ) and antifreeze mixed with preferably distilled water ( usually 50 / 50 , Ford states not to exceed 60% antifreeze in the mix ) will also raise the boiling point of the engine coolant as well as lowering the freezing point
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".
Yes. It raises the boiling point of the water it's mixed with so it won't turn into a gas at 100 degrees C.
