Q:

How much antifreeze should one put in one's car?

A:

Quick Answer

A mix of 50 percent antifreeze to 50 percent water is usually sufficient in most areas. In more extreme climates, the mix may be different and must be altered to suit that climate.

Full Answer

Modern antifreeze no longer just protects an engine from cold temperatures. It also raises the boiling point of the water to enable better summer cooling. Most cars manufactured after 1998 require an antifreeze which contains silicate-free, organic acid technology. Too little coolant in a car can cause the car to blow out cold air through the heater and the temperature gauge to read cool. This is because there is no hot water going thorough the heating matrix, and the temperature sensor needs to be in water for it to read accurately.

  • Q:

    What happens to a car when antifreeze leaks?

    A:

    If the antifreeze leaks from a car, the engine is likely to overheat. If the driver continues to operate the overheated vehicle, it is likely that major engine damage occurs. AA1Car.com says drivers should never ignore a hot warning light or temperature gauge that moves into the red.

  • Q:

    How do you bleed a radiator?

    A:

    To bleed a radiator, fill the radiator and the coolant reservoir with a mixture of water and antifreeze, and run the engine with the radiator cap off until the air in the radiator escapes. Finally, refill the radiator and the coolant reservoir to the top, and replace the radiator cap.

  • Q:

    At what temperature does antifreeze freeze?

    A:

    Anti-freeze typically is rated to freeze at minus 34 F. The freeze point includes the recommended 1-1 ratio of antifreeze with water. If the mixture is altered to a blend that includes 70 percent antifreeze to 30 percent water, the freeze point of the product becomes minus 67 F.

  • Q:

    How much antifreeze does a radiator hold?

    A:

    The precise amount of antifreeze a radiator holds depends upon the size and make of the car, but the solution in a car radiator should be a mix of about 50 to 60 percent antifreeze and 40 to 50 percent water. Freeze protection doesn't improve by running the engine with a higher percentage of antifreeze.
