Drain it out.
6 litres of 40% and 2 litres of 80%.
In America we don't DO liters. Approximately 2 gallons. Mix half and half with antifreeze.
6 litres of the 30% and 4 litres of 60%.
Seven liters.
50 % water to anti freeze mix its about 8 liters in a 406 so 4liters of anti freeze 4 liters of water
Approximately 2,000 pounds.
7 liters, I'm not sure if u can use any antifreeze though..
To have a 50 / 50 mixture of antifreeze and preferably distilled water you would need ( 7.5 liters / 7.9 quarts ) of antifreeze because according to the Owner Guide the cooling system capacity is 15.0 liters / 15.8 quarts Ford shows not to exceed 60 % antifreeze and not to drop below 40 % antifreeze in the cooling system
The coolant system capacity of the 2004 Ford Mustang GT is : 14.1 quarts ( 13.3 liters ) 50 / 50 mixture of antifreeze and preferably distilled water ( so just over 7 quarts / 6.6 liters of antifreeze )
The coolant system capacity is 31.0 liters (32.75 quarts ) including the heater and the coolant recovery tank ( so , with a 50 / 50 mixture of antifreeze and preferably distilled water , 15.5 liters / 16.375 quarts of antifreeze )
According to the 1999 Ford Escort owners manual : The cooling system capacity with a manual transmission is 5.3 quarts / 5.0 liters The cooling system capacity with an automatic transmission is 6.3 quarts / 6.0 liters So , with a 50 / 50 mix of antifreeze and preferably distilled water : The cooling system with a manual transmission takes 2.65 quarts / 2.50 liters of antifreeze The cooling system with an automatic transmission takes 3.15 quarts / 3.0 liters of antifreeze T
