How much radiator coolant to use

Warning : Before checking the antifreeze in your vehicle, allow the engine to cool completely to avoid burns. You should also check your antifreeze while it is at room temperature to get the best reading. Tip : Make sure to use an antifreeze hydrometer and not one designed for use with checking the acid content of the fluid in your vehicle's battery.

While hydrometers come in a wide variety of styles, the most common have little floating balls within it of varying colors or arrows that point to temperatures on a scale printed directly on the hydrometer that help determine the strength of the coolant solution.

Part 3 of 3: Calculating the proper water to antifreeze ratio Once you have determined the protection level of your vehicle, it is time to determine how much antifreeze or water you need to add.

That is why it is imperative to ensure your engine coolant is not old and deteriorating. Engine coolant is the liquid that surges through your engine removing heat and keeps your car from overheating.

This is no easy feat considering the controlled engine explosions that move your car forward get up to around degrees F. These can lead overall engine temperatures up into the degree Fahrenheit range when you are driving continuously. To do its job properly, the fluid that gets pumped through your engine and prevents catastrophic heat damage MUST have a very low freezing point and a very very high boiling point.

To accomplish these goals, we use a solution typically referred to as engine coolant. It is common for an additive called antifreeze to be included as a large part of this solution. Though antifreeze in its pure state actually freezes and boils more quickly than water, when it is mixed at a proper proportion with water, it actually lowers the freezing point of the mixture and increases the boiling point.

It also prevents corrosion in your engine. Coolant is generally a ratio of antifreeze to water. Water freezes at 32 degrees and boils at degrees. If that liquid were to freeze it would break your engine. If the fluid reaches a boiling point it will no longer be able to serve as a heat transfer between the hot metal in the engine block and the car will overheat.

Engine overheating causes warping of several important components of the engine like the aluminum cylinders, engine head gasket and water pump. When water is mixed with antifreeze which is made of a chemical called ethylene glycol , the freezing point is bumped down to degrees and the boiling point raised to degrees Fahrenheit.

Though people use the terms interchangeably, coolant and antifreeze are actually not the same thing. Engine coolant refers to the liquid mixed solution that surges through the engine block in your car keeping it from overheating. It is important to note that it is a solution, meaning it is made up of a mix of several substances.

Engine coolant is a pre-mixed solution which will contain antifreeze. Alternatively, you can buy antifreeze as a concentrate and mix it with softened water and make your own, if you know what you are doing. Antifreeze is a chemical, ethylene glycol, which is found in most premixed engine coolants that are ready to be added to your vehicle. To reiterate, your options here are to purchase a premixed engine coolant that is ready to be added to your empty, clean, engine coolant compartment in your car.

Or you can purchase anti-freeze and mix a ratio with softened water. Always read the mixing instructions to verify safety procedures and mixing ratios which may vary from brand to brand. I have included some information further along in this article to help you clean out your engine coolant system of all old, used and dirty coolant and to help you dispose of it properly.

Please be sure to keep your used and replacement coolant away from animals it tastes sweet to them and they will drink it. Make sure the coolant level remains in the same place. If it does down, there is a leakage, or the coolant is being burned up in the cylinders. So, you can add more coolant to the already existing coolant. Typically, silicate coolant lasts up to 2 years or 30, miles, while extended drain coolant lasts up to 5 years or , miles.

Note that you can differentiate between coolants from the coolant color. Some cooling systems can hold around 5 liters of coolant. Typically, auto repair shops sell engine coolant in liter containers, which you can select the liters you need for your vehicle.

You can tell how many liters you need by looking up your number plate on websites such as VinCheck. Some auto repair shops offer incentives and bonuses, which means you could be replacing coolant for your vehicle at less cost.

Note that the estimated cost I provide here does not include tax and other charges. Meanwhile, if you are selling your car and the buyer requests proof that you refilled the coolant recently, you can create an auto repair receipt indicating coolant refill and issue it to them.
