Considering Toyota Corrolla family car, how much coolant is required for flushing and replenishment ?

One gallon of straight antifreeze will do .
When you get done flushing the cooling system drain the radiator.
When adding the antifreeze pour 1/2 gallon of straight antifreeze into the radiator first. Then top up the remaining half gallon with water to make a 50/50 mixture. Add the remaining mixture and run the motor for 15 minutes with the radiator cap off to purge all the air out. You'll end up with a -35 degree Fahrenheit protection level that way.Source(s): Mitsubishi Master Tech
