Coolant To Water Ratio Chart

This usually ranges anywhere between 8 to 18 liters.

Coolant to water ratio chart. If your mix ratio is 4 1 or 4 parts water to 1 part solution there are 4 1 or 5 parts. Increasing the ratio of the antifreeze to water such as a 70 30 mix will lower the freezing point of the mix down to minus 72 degrees fahrenheit but it will also lessen its ability to cool the engine. Further increasing the proportion of antifreeze e g. Enter the maximum possible volume of liquid in the radiator and cooling system.

The mixing ratio of water and antifreeze should lie between 60 40 and 50 50. Improperly maintained coolant. This usually corresponds to antifreeze protection from 25 c to 40 c. In most places including your local gas station you can buy pre mixed coolant which is usually 50 50 anti freeze and water.

If you are new to mixing and maintaining coolant we recommend that you start with tools of coolant. Be sure to maintain your coolant mixture to keep the coolant concentrate at acceptable levels. Divide 1 by the total number of parts water solution. This gives the coolant an adequate amount of freezing and boiling protection while also providing the corrosion protection the engine and radiator need.

The general recommendation by antifreeze manufacturers is to have a 50 50 antifreeze and water mix. Getting your coolant mix right is the key to ensuring your engine has optimal freeze and boil protection. These coolant mixers use ratios to mix the chemical concentrate and water. The mixing percentage is 11 1 1 divided by 9.

This standard ratio is an attempt to encompass as much of the nation as possible and will provide great anti freeze and anti corrosion protection. Most manufacturers suggest a 50 or 1 to 1 mixture of coolant and water for best cooling of the engine. Vehicles such as cars and light trucks require an antifreeze to water ratio of 50 50. For example if your mix ratio is 8 1 or 8 parts water to 1 part solution there are 8 1 or 9 parts.

Following is how to make sense of the ratio to concentration relationship. Based on environment you may want to change that percentage. Find the coolant capacity of your vehicle. 30 70 does not lower the freezing point any further.

Metalworking sump fluids can range 2 around your target concentration. After taking a quick reading with your own antifreeze tester you can adjust your mix by using our calculator to find out the recommended amount of coolant you need to drain and replace with antifreeze or water.
